South St. Paul Public Schools Grapple with Ongoing Tech Disruption

 

South St. Paul Public Schools recently alerted families to ongoing technology disruption, shedding light on potential disruptions to online platforms, emails, and other digital services. In a note on Monday, the district acknowledged technical difficulties and later revealed the presence of "unauthorized activity" within its computer network. 

Upon discovering the unusual activity, the district swiftly took its systems offline to isolate the issue. To address the situation comprehensively, South St. Paul Public Schools enlisted the assistance of a third-party cybersecurity firm. This partnership aims not only to recover systems but also to investigate the cause and scope of the unauthorized activity. 

The district actively focuses on restoring all systems, emphasizing the importance of maintaining a productive learning environment for students and staff. Acknowledging the inevitability of cyber threats in today's interconnected world, South St. Paul Public Schools reassured families that proactive steps had been taken to create a secure online environment. 

This incident adds to a series of cybersecurity challenges faced by educational institutions in the region. In a previous case, the St. Paul school district notified over 43,000 families about a "data security incident" in February 2023. Fortunately, only student names and email addresses were compromised in the unauthorized access. 

The University of Minnesota also grappled with a data breach last year, exposing personal information spanning 30 years, from 1989 to August 2021. The breach targeted names, addresses, phone numbers, Social Security numbers, driver’s licenses, and passport information. Minneapolis Public Schools faced a ransomware attack in the same year, exposing confidential student documents online. 

The refusal to pay a $1 million ransom led to the compromise of sensitive data, including sexual assault cases, medical records, and discrimination complaints. South St. Paul Public Schools' proactive approach to addressing the ongoing technology disruption showcases the importance of swift action and collaboration with cybersecurity experts. 

As educational institutions continue to face digital threats, it becomes imperative for them to prioritize robust security measures, ongoing vigilance, and prompt response strategies. In an era where technology is deeply integrated into the educational landscape, the South St. Paul incident serves as a reminder of the ever-present challenges in safeguarding digital infrastructures. Educational institutions must remain vigilant, continually adapting to the evolving threat landscape to ensure a secure and uninterrupted learning experience for students and staff.

Web-Based PLC Malware: A New Frontier in Industrial Cybersecurity Threats

 

The increasing prevalence of programmable logic controllers (PLCs) featuring embedded web servers has opened avenues for potential catastrophic remote attacks on operational technology (OT) within industrial control systems (ICS) in critical infrastructure sectors. 

Researchers from the Georgia Institute of Technology have developed malware that could enable adversaries to remotely access embedded web servers in PLCs, potentially leading to manipulation of output signals, falsification of sensor readings, disabling safety systems, and other actions with severe consequences, including loss of life. PLCs are integral components of ICS, responsible for controlling physical processes and machinery in manufacturing, industrial, and critical infrastructure settings. 

Malware targeting PLCs typically aims to disrupt or sabotage the physical processes they control. The newly developed web-based PLC malware differs fundamentally from traditional PLC malware. Unlike previous versions that required prior physical or network access, the web-based malware attacks the front-end web layer in PLCs using malicious JavaScript. 

This approach eliminates some limitations faced by previous malicious code, providing advantages such as platform independence, ease of deployment, and higher levels of persistence. Historically, PLC malware-infected firmware or control logic, requires specific access or is easily erasable via factory resets. The web-based malware targets the web layer, making it fundamentally different and more challenging to mitigate. 

The outcomes of cyberattacks using this new strain of malware mirror those of previous successful PLC attacks, including the infamous Stuxnet campaign that targeted Siemens PLCs to dismantle high-speed centrifuges at Iran's Natanz uranium enrichment facility. While other attacks, such as BlackEnergy, Triton/Trisis, and INCONTROLLER, have demonstrated the potential damage to systems controlling physical processes, the Georgia Tech researchers' web-based PLC malware offers a more persistent and easier-to-deploy method. 

The researchers conducted a proof-of-concept cyberattack in a scenario resembling a Stuxnet-like attack on a widely used PLC controlling an industrial motor. The PLC featured a web-based interface for remote monitoring, programming, and configuration. In their test scenario, the researchers explored how an attacker could gain initial access to the PLC by remotely injecting malicious code into the web server. 

The web-based PLC malware allowed the attacker to physically damage the industrial motor, manipulate admin settings for further compromise, and steal data for industrial espionage. The unique aspect of this web-based PLC malware lies in its residence in PLC memory while being executed client-side by various browser-equipped devices across the ICS environment. The malware utilizes ambient browser-based credentials to interact with the PLC's legitimate web APIs, facilitating attacks on real-world machinery. 

This type of malware presents challenges for defenders due to its ease of deployment and platform-agnostic nature. As industrial systems continue to integrate web-based interfaces for remote access and monitoring, the security community must stay vigilant to address evolving threats like web-based PLC malware and ensure the resilience of critical infrastructure against potential cyber-physical attacks.

Cybersecurity Nightmare Unfolds as Malawi's Immigration Systems Under Attack

 


There has been a recent cyberattack on Malawi, according to President Lazarus Chakwera, which has caused the government to stop issuing passports. However, some observers believe such an attack did not occur. Chakwera informed parliament on Wednesday that security measures were in place to identify and apprehend the attackers who compromised the country's security. 

It was his statement that the attackers were demanding millions in ransom, but the administration was unwilling to pay it. The hacker has been causing the Department of Immigration and Citizenship Services' passport printing system to malfunction over the past three weeks, according to him. In Malawi, there is a high demand for passports with many young people seeking to migrate to find employment. 

As a result of Mr Chakwera's request, the immigration department is expected to provide a temporary solution within three weeks of regaining control of the system to resume passport issuance. There would be an additional security safeguard developed as part of the long-term solution, he said. 

In his address on Wednesday, Chakwera said that he had given the immigration department a three-week deadline to provide a temporary solution to the passport printing issue and to resume printing of passports. He further said at the same event that he had reassured hackers that the Malawi government would not pay ransoms. As a result of the government's termination of the contract with Techno Brain, which had supplied Malawi’s passports since 2019, Malawi has experienced passport issues since 2021. 

As a result of the government's inability to find a replacement for the company in 2023, the company was re-engaged temporarily. Nevertheless, immigration officials often had to scale back production due to shortages of materials or unpaid bills, which resulted in them having to scale down production several times. In addition to being the executive director of the Center for Democracy and Economic Development Initiatives, Sylvester Namiwa is also a member of the organization that has threatened to hold protests within the coming days if it does not receive an immediate resolution. 

According to Chakwera, he has questioned the integrity of the claim that the system had been hacked by someone else. During a radio interview with a local radio station on Thursday, Malawi's Information Minister Moses Nkukuyu explained that the information Chakwera presented in parliament had been provided by immigration experts. VOA's calls and texts to Wellington Chiponde, a spokesperson for the immigration department, were not responded to.

ALPHV Ransomware Strikes: LoanDepot and Prudential Financial Targeted

 


Recently, Prudential Financial and loanDepot, two Fortune 500 companies were attacked by the ALPHV/Blackcat ransomware gang, which claims responsibility for the breaches. Despite the threat actors still having to prove their claims, the two companies were added to ALPHV's dark web leak site today, which is the first time the threat actors have added them to the dark web leak site. As a result of failed negotiations, ALPHV will be selling the stolen data from loanDepot's network and releasing Prudential's data for free as well. 

There was a data leak on the site of the infamous ALPHV ransomware operator - the BlackCat group - that revealed Prudential Financial and loanDepot as being the targets of the attacks on both firms, as an apparent admission by the group that it had been behind the attacks on these firms. Currently, the group has only added the names to its site, while the actual data has not yet been available. Because negotiations with Prudential Financial broke down, the group will be publishing its database for free for all to see. 

A company representative stated that the company would provide free credit monitoring and identity protection to those affected by the data breach. With roughly 6,000 employees and more than $140 billion in loan servicing in the United States, loanDepot is among the largest nonbank retail mortgage lenders in the U.S. A suspected cybercrime group breached Prudential Financial's network on February 4 and stole employee and contractor data. 

Prudential Financial also revealed on Tuesday that this breach occurred on February 4. Despite Prudential's ongoing investigation of the incident, it has not been determined if the attackers also exfiltrated customer or client data, even though the incident is being assessed in its full scope and impact. With revenue expected to exceed $50 billion in 2023, this Fortune 500 company will rank second in the world for life insurance companies in the U.S. 

They employ more than 40,000 people around the world. As part of the State Department's announcement, rewards of up to $10 million are being offered for tips that could lead to the identification or location of ALPHV gang leaders. 

During the first four months of this gang's activity between November 2021 and March 2022, it was linked to more than 60 breaches around the world, and an additional $5 million reward was offered for information on individuals who were either involved or attempted to be involved in ALPHV ransomware attacks. 

Law enforcement agencies estimate that ALPHV will have received at least $300 million through ransom payments from over 1,000 victims by the end of September 2023, as per the law enforcement agency. The Prudential Financial Corporation (Prudential Financial) filed an 8-K form with the Financial Industry Regulatory Authority (FINRA) last week detailing the incident that occurred. 

Although the company is still investigating the incident, its latest findings were that no sensitive information concerning its customers or clients was compromised. More than 40,000 people work for Prudential every year, and as a result, the company has more than $50 billion in revenues each year, making it one of the world's largest financial services companies. 

As a result of the new information, which comes shortly after the U.S. Upon receiving information that could help identify or locate ALPHV leaders, the State Department offered up to $10 million, with an additional $5 million for information on those who participated (or attempted to participate) in the ALPHV ransomware attack, for information that could lead to that identification. 

One of the most popular and active ransomware groups, next to LockBit, or Cl0p, is ALPHV. It has made headlines across the globe for its activism and popularity. In the latter half of 2021, it became apparent that DarkSide and BlackMatter had merged, possibly after these two companies merged. ALPHV and its affiliates are believed to have extorted hundreds of millions of dollars from its victims during its lifetime.

Indian SMEs Lead in Cybersecurity Preparedness and AI Adoption

 

In an era where the digital landscape is rapidly evolving, Small and Medium Enterprises (SMEs) in India are emerging as resilient players, showcasing robust preparedness for cyber threats and embracing the transformative power of Artificial Intelligence (AI).

In the dynamic realm of cybersecurity, discovering a significant flaw in every Linux boot loader signed in the past decade has underscored the pervasive nature of potential threats. This blog explores the intricacies of the Shim bug, its implications for Linux systems, and the urgent response required to mitigate its impact. 

The Shim bug, a critical vulnerability affecting Linux boot loaders, has sent security experts into a heightened state of alert. The flaw lies in the code of the Shim bootloader, a crucial component in the Secure Boot process designed to ensure the integrity of the boot sequence. The bug itself has silently persisted for an astounding ten years, evading detection until now. 

The far-reaching impact of the Shim bug cannot be overstated, as it compromises the security of every Linux boot loader signed over the past decade. Secure Boot, a fundamental security feature, is designed to prevent the loading of unsigned or malicious code during the boot process. However, this vulnerability allows threat actors to bypass these protections, opening the door to unauthorized access, malware injection, and other malicious activities. 

The longevity of the Shim bug's existence without detection raises questions about the efficacy of current security measures and the challenges inherent in identifying hidden vulnerabilities. Its discovery highlights the need for ongoing scrutiny, even of well-established and seemingly secure components within the Linux ecosystem.

Patient Privacy in Focus: Healthcare's Cyber Challenges





Amidst the rapid evolution of technology in healthcare, a crucial focus has come to light: the security of medical devices. Let's explore the intricacies of this issue together, understanding its importance and finding the right balance between advancing technology and strengthening our healthcare foundation. 

The Growing Threat 

Healthcare systems are prime targets for hackers looking to snag valuable patient data. This isn't just a disruption in patient care – there's a twist involving our medical gadgets. Beyond compromising records, even medical devices like MRIs and ventilators face potential risks, especially those running on outdated software. 

Government Recommendations 

A recent government watchdog recommended increased collaboration between the Food and Drug Administration (FDA) and the Cybersecurity and Infrastructure Security Agency (CISA) to enhance the security of medical devices. Although these devices haven't been the primary focus of cyber threats, their vulnerabilities pose risks to both hospital networks and patient well-being. 

Expert Insights 

Toby Gouker from First Health Advisory emphasises the critical nature of this issue, describing it as a significant vulnerability for health systems. Recognizing this weakness, healthcare providers must prioritise cybersecurity efforts, particularly concerning medical devices, to ensure the safety of patient data and uninterrupted healthcare services. 

Challenges in Legacy Devices 

Looking ahead, the focus on device security is not just a theoretical concern; according to Gouker, these devices will likely become more attractive targets as health systems improve their defences against hacking attempts targeting health records. Gouker emphasises the financial impact, pointing out that high-value devices like MRIs are often the backbone of hospital revenue. Disrupting these multimillion-dollar machines could potentially cripple entire health systems. 

Regulatory Measures and Connectivity Concerns 

A crucial detail is that, since March of the previous year, a new law mandates manufacturers to submit cybersecurity plans for new medical devices to the FDA. However, this regulation doesn't extend to the plethora of already-existing connected devices. Chelsea Arnone from the College of Healthcare Information Management Executives highlights the widespread connectivity, noting that everything from hospital beds to infusion pumps and vital-sign monitors is online and thus susceptible to hacking. Many of these devices use off-the-shelf software vulnerable to threats like viruses and worms. 

Urgent Need for a Comprehensive Approach 

Despite recent requirements for new devices, manufacturers have historically not been obligated to provide patches or solutions for vulnerabilities in ageing devices, although some have done so for a limited period. This information underscores the urgent need for a comprehensive approach to address cybersecurity risks in the evolving landscape of medical devices. 

Real-world Incident and Awareness Gap 

In a recent incident, a hospital discovered unauthorised access to a medical device from Russia, stressing on the challenges in addressing cybersecurity threats. An FDA report suggests managing cybersecurity risks for legacy devices, but only a fraction of health systems implement such measures due to cost and awareness issues. There's a pressing need for heightened awareness and cost-effective solutions to fortify medical device cybersecurity across healthcare organisations. 

In addressing healthcare cybersecurity challenges, bureaucratic obstacles appear to be of great concern, causing delays and inefficiencies in responding to hacking threats. Streamlining these processes is paramount. Be attentive, advocate transparency, and support efficient protocols to secure our healthcare systems against burgeoning cyber threats.



Securing Wearable Devices: Potential Risks and Precautions

 

In the rapidly evolving landscape of digital security, individuals are increasingly vulnerable to cyber threats, not only on conventional computers and smartphones but also on wearable devices. The surge in smartwatches and advanced fitness trackers presents a new frontier for potential security breaches.

Just like traditional devices, wearables store and transmit valuable data, making them attractive targets for hackers. If successfully compromised, these devices could become conduits for unauthorized prescription orders or even allow the tracking of an individual's location through the embedded GPS feature. The threat extends beyond personal wearables, with concerns arising about vulnerabilities in medical offices and equipment. The FDA has issued warnings about potential loopholes that hackers could exploit to target critical medical devices such as pacemakers and insulin pumps.

The risk isn't confined to personal privacy; there's a growing concern about the impact a hacked wearable could have on corporate networks. With the proliferation of connected devices, a compromised smartwatch might provide an easier entry point for hackers seeking to infiltrate company systems, especially if the wearable syncs with multiple networks.

One notable vulnerability lies in the Bluetooth connection that wearables commonly share with smartphones. While any internet-connected device carries inherent risks, wearables often use smartphones as intermediaries rather than operating as standalone devices. Presently, security compromises have mainly originated from devices connected to wearables or compromised external databases, making wearables a theoretical but legitimate concern.

To mitigate these risks, users are advised to exercise caution when installing apps on their wearables. Verifying the legitimacy of sources, checking user reviews, and researching app safety are essential steps to ensure the security of wearable devices. This advice extends to smartphones, where users should scrutinize app permissions, restricting access to unnecessary information and promptly deleting suspicious apps.

In this era of pervasive connectivity, safeguarding personal and corporate data requires a proactive approach, extending beyond conventional devices to include the emerging frontier of wearable technology.

Australian SMBs Faces Challenges in Cyber Security


The internet has turned into a challenge for small to midsize businesses based in Australia. In addition to the difficulty of implementing innovative technology quickly and with limited resources because of the rate of invention, they also face the same cyberthreats that affect other organizations. Then, as 60% of SMBs close following a breach, companies that are breached are likely to fail later.

This has raised concerns of the regulators. 

According to a recent report by ASIC, ‘medium to large’ business firms are recently been reporting severe cyber security capabilities in comparison to other organizations, including supply chain risk management, data security, and consequence management.

In response to the aforementioned threats, the Australian government has announced an AU $20 million package to boost small businesses. An optional cyber "health check" program is being established as part of this to assist small business owners in assessing the maturity of their cyber security. A Small Business Cyber Resilience Service, which will offer a one-on-one service to assist small firms in recovering from a cyber assault, will also receive $11 million of the package. 

This initiative will focus on areas where SMBs are the most vulnerable. However, small firms will also need to take it upon themselves to place a lot greater emphasis on resilience than they have been doing in the face of growing cyber threats. 

The Risk in Numbers 

The ASIC research analysis found that small businesses are only slightly more effective than half of their medium and big counterparts in several areas, such as identifying threats and overcoming them.

The significant percentages of small businesses are as follows:

  • Do not follow or benchmark against any cyber security standard (34%).
  • Do not perform risk assessments of third parties and vendors (44%).
  • Have no or limited capability in using multi-factor authentication (33%)./ Do not patch applications (41%).
  • Do not perform vulnerability scans (45%). Do not have backups in place (30%).

The Cost to Small Business

The Annual Cyber Threat Report 2022-23 published by the Australian Signals Directorate reveals that the average cost of cybercrime has increased by 14% over the past year. Small firms paid $46,000, medium-sized organizations paid $97,200, and bigger enterprises paid $71,600.

Of course, that is a financial burden for any business, but it seems to be especially harmful for SMBs. Approximately 60% of small firms that experience a breach ultimately go out of business as a direct result of it.

These organizations face a real existential threat from cyber security. Even those who manage to escape the breach's direct costs still have to deal with the harm to their reputation, which can cost them partners and customers as well as short-term cash flow. In the best-case scenario, a cyberattack "just" prevents the small business from expanding and growing.

What can Small Businesses do? 

After identifying the restrictions on resources available to small businesses, the ASD and Australian Cyber Security Centre have designed the Essential Eight, a set of best practices for security and small enterprises. These are as follows:

  • Creating, implementing and managing a whitelist of approved applications. 
  • Implementing a process to regularly update and patch systems, software and applications.
  • Disabling macros in Microsoft Office applications unless specifically required, and training employees not to deploy macros in unsolicited email attachments or documents. 
  • Securing the configuration of web browsers to prevent harmful content, hence hardening user applications. Keeping browser extensions up to date and only using those that are required.
  • Restricting administrative privileges to those who need them. 
  • Configuring operating system patching through automatic updates.
  • Using strong, unique passwords and enabling multi-factor authentication. 
  • Isolating backups from the network and performing daily backups of important data.  

Sekoia Reports: Latest in the Financial Sector Cyber Threat Landscape


France-based cybersecurity company Sekoia published a new report regarding the evolution in the financial sector threat landscape. 

Among the many cybersecurity issues, phishing attacks like QR code phishing were the ones that have seen a massive surge in the sector.

Also, the report noted that the finance sector is subject to attacks on the software supply chain. 

Phishing as a Service Massively Hits the Sector

Sekoia claims that in 2023, the phishing-as-a-service paradigm reached widespread use. Cybercriminals are selling phishing kits that comprise phishing pages that mimic various financial institutions, as well as kits designed to take over Microsoft and obtain login credentials for Microsoft 365, which businesses utilize to authenticate to multiple services.

One instance of such a threat is NakedPages PhaaS, that offers phishing pages for varied targets, among which are the financial institutions. With over 3,500 individuals, the threat actor maintains licenses and frequently posts updates on its Telegram channel.

In regards to the aforementioned number, Sekoia based strategic threat intelligence analyst, Livia Tibirna says “generally speaking, cybercrime actors tend to increase their audience, and so their visibility, by inviting users to join their public resources. Therefore, the users are potential (future) customers of the threat actors’ services. Yet, other type of users joining threat actors’ Telegram resources are cybersecurity experts monitoring the related threats.”

QR Code Phishing Campaigns are on the Rise/ Sekoia reports an upsurge in the quantity of QR code phishing, or quishing, activities. Attacks known as "quishing" include using QR codes to trick people into divulging personal information—like login passwords or bank account details.

The cybersecurity firm notes that QR code phishing will eventually increase due to its “effectiveness in evading detection and circumventing email protection solutions.”

According to Sekoia, the most popular kit in Q3 of 2023 is the Dadsec OTT phishing as a service platform, which includes quishing features. It has been noted in a number of extensive attack campaigns, specifically posing as financial institutions.

Multiple Supply Chain Risks

Attacks against the supply chain of open-source software increased by 200% between 2022 and 2023. Since open-source components are used in digital products or services by 94% of firms in the financial sector, the industry is susceptible to attacks that take advantage of supply chain compromises involving open-source software.

One of the examples is the Log4Shell vulnerability and its exploitation, that has targeted thousands of companies globally for financial benefits and espionage. 

There have also been reports of supply chain attacks that particularly target the banking industry, demonstrating the potential of certain threat actors to create complex attacks against the industry.

"It is highly likely that advanced threat actors will persist in explicitly targeting the software supply chain in the banking sector," according to Sekoia.

Financially Oriented Malware 

Sekoia also mentioned some of the financially oriented malware that are predominantly designed to steal financial data, like credit card information, banking credentials, crypto wallets and other critical data, like: 

Mobile Banking Trojans: Sekoia has expressed special concern about the growing number of Trojans associated with mobile banking, which more than doubled in 2022 compared to the previous year and is still growing in 2023. According to Sekoia, this is probably because more mobile devices are being used for financial services, and that malware makes it easier to get around two-factor authentication.

Spyware: According to Sekoia, the usage of spyware, which are malicious programs made to gather passwords, sensitive data, and keystrokes, has increased in bank fraud in 2023. One kind of Android malware is called SpyNote, and it has added targeting of banking applications to its list of features.

Ransomware: The finance industry is a prime target for ransomware; in the third quarter of 2023, it was the sector most affected. Ransom demands ranged from $180,000 to $40 million, and in many instances, they had severe physical repercussions.

According to Sekoia, well-known ransomware actors that use extortion to affect the financial industry, like BianLian, have changed to an exfiltration-based extortion strategy that does not encrypt the victims' systems or data. This action is probably taken to prevent widespread encryption issues during large-scale hacking operations.

Reduce Cyber Threat Risks

The financial sector is vulnerable to several security risks. Although BEC and phishing have been around for a while, they have become more sophisticated over time to continue to impact the industry and stay up with emerging technologies. Every employee of financial institutions needs to be trained to recognize potential fraud or phishing efforts. Additionally, they want to have a simple method for informing their IT staff of any unusual activities.

However, more indirect attacks have recently entered the chart, since threat actors have been targeting organizations through supply chain attacks. Specifically, before being implemented, open-source software utilized in goods or services needs to be thoroughly examined.  

Guarding the Gate: How to Thwart Initial Access Brokers' Intrusions

 


The term "Access-as-a-service" (AaaS) refers to a new business model in the underground world of cybercrime in which threat actors sell one-time methods to gain access to networks to infiltrate networks for as little as one dollar. 

One group of criminals, which are known as access brokers, initial access brokers, and initial access traders (IABs), are stealing credentials of enterprise users and selling them to other groups of attackers. There are also encryption tools that can be used by these buyers to secretly exfiltrate your personal information from the target organization using malware-as-a-service (MaaS) or ransomware-as-a-service (RaaS). 

Cybercrime-as-a-service (CaaS) is a growing trend that is increasingly being used as a platform for committing crimes. A significant portion of the evolution of ransomware attacks over the last decade has taken place at both the technological level and organizational level as threat actors have attempted to expand the scope and profitability of their operations. 

A pivotal factor behind the widespread increase in the frequency and complexity of ransomware attacks can be attributed to the provision of ransomware as a service (RaaS). RaaS, which operates much like SaaS, and involves the creation of ransomware capabilities and selling or leasing them to buyers, has lowered the barrier to entry for the extortion business and provided a simpler and more accessible model. 

There are now a number of operators working together in unison to orchestrate the attacks in order to achieve the goal, including Users, Affiliates, and Initial Access Brokers, who act as a cohesive team. According to the recent report, "Rise of Initial Access Brokers", these intermediaries, which are the first to get access to cyberattack victims, are playing a key role at the top of the kill-chain funnel of cyberattacks. 

An independent analysis bureau (IAB) can be defined as a de facto intermediary whose business model is exactly what their name suggests: they breach the networks of as many companies as they are able to. Upon accessing victims, they then sell to the highest bidders at the highest prices. There is a tendency for ransomware groups to buy the ransomware from the buyers. 

A growing number of independent advisory boards have been formed recently mainly as a result of the pandemic and the ensuing migration to work from home. As a result of workers log in remotely and connecting to untrustworthy Wi-Fi networks, untrustworthy Wi-Fi networks can be exploited to allow attackers to gain access to systems.

There is a growing trend among cybercriminals of scanning at scale for vulnerabilities that will allow them to access remote systems, such as virtual private networks (VPNs) and selling this access to their victims. Once the details of a vulnerability are made public, the Information Assurance Business deploys info stealers to gather keystrokes, session cookies, credentials, screenshots and video recordings, local information, browser history, bookmarks, and clipboard material from the compromised device as soon as the details are made public. 

As soon as an information stealer is installed in an organization or system, a remote access Trojan (RAT) will begin to collect raw log files to log information. As a result, these logs are manually reviewed to identify usernames and passwords that may be used to sell or monetize identities on the Dark Web. This means that IABs are seeking login credentials to access virtual private networks (VPNs), remote desktop protocols (RDPs), Web applications, and email servers that will aid in the recruitment of spear phishing scammers and potential business email compromise schemes. Occasionally, some brokers have direct contact with system administrators or end users who may be willing to sell access to their systems directly through them. 

Threat groups have been advertising (on the Dark Web) in recent months for administrators and end users who are willing to share their credentials with them in exchange for large amounts of cryptocurrency in exchange for sharing credentials for a few minutes. 

Threat groups have contacted employees from specific organizations to obtain access to their systems in exchange for larger payments. It is safe to say that initial access brokers have taken the spotlight in the past year because they have demonstrated a significant ability to facilitate network intrusions by ransomware affiliates and operators, and they have been very successful at it. As the cybercrime underground ecosystem becomes more active and popular, these initial access brokers ("IABs") will continue to gain popularity as the cybercrime underground ecosystem grows. 

A Guide to Defending Against Access Brokers 


Users should identify their attack surface and develop a plan to address it, to close security gaps, security teams must gain an outside-in perspective on their entire enterprise attack surface. Empower user security teams to map their assets, visualize attack paths, and define plans to address them so that they can close the gaps.  

Identity protection should be considered a priority, today, plenty of malware-free attacks, social engineering, and similar attempts have been made to steal and use credentials, making it crucial that strong identity protection is implemented. Employees need to be taught about social media, not just how to use it. 

Avoid announcing department closures or IT service changes on social media, and remind them to refrain from sharing private information on social media. Users should train their staff not to share credentials over support calls, emails, or support tickets. 

Finally, users should avoid publishing executive or IT contact information on their company's website — it might facilitate impersonation attempts on their behalf. 

To protect the cloud, a strong cloud protection strategy is required. There have been increasing attacks on cloud infrastructure and attackers have been employing a variety of tactics, techniques, and procedures to compromise cloud-based data and applications that are critical to businesses. 

The role of IABs in the realm of RaaS (Ransomware-as-a-Service) is continuously evolving. By understanding and keeping up with their shifting tactics, methods, and trends, organizations can better prepare themselves to effectively mitigate the risk and impact of ransomware attacks. As IABs continually remodel and refine their strategies, it becomes increasingly crucial for organizations to adopt and implement robust security measures. 

Strengthening the security of the supply chain, implementing multi-factor authentication across all systems and platforms, deploying advanced threat-hunting solutions to proactively detect and prevent attacks, and conducting regular and comprehensive training sessions for employees are key steps that organizations should take to effectively mitigate the growing threat posed by IABs.

Ransomware Kingpin Behind Ragnar Locker Arrested in Paris

 


An international law enforcement action coordinated by European Interpol and officials of foreign law enforcement agencies led to the removal of the Ragnar Locker ransomware group on October 20, 2023. Various law enforcement agencies including the French, American, and Japanese law enforcement agencies were involved in the operation, which was conducted by Eurojust and Europol jointly. A notice stating that the group had seized the websites was posted on the group's Tor negotiation and data leak websites indicating that the websites had been taken down. 

As part of a joint international operation, law enforcement agencies arrested a malware developer linked to the Ragnar Locker ransomware gang and seized their dark websites that were previously used to distribute the malware. 168 international companies are believed to have been hit by attacks by the Ragnar Locker ransomware gang since 2020, and throughout that time, they have made over $1 million in profits. 

In a related operation, which was conducted on October 18 and 19 in Paris, a "key target" said to have been involved in the Ragnar Locker ransomware group was arrested as part of this operation. A report on one of the EU's official news outlets, Europa, claims that the developer of the ransomware has also been arrested, in addition to the victim of the ransomware. Law enforcement agencies from around the world have collaborated to make these arrests possible. 

There was an arrest in Paris, France, on October 16, of the "main leader" of the malicious ransomware that was circulating on the Internet. It was also reported that his home in the Czech Republic had been raided by the police. It was found that the alleged leaders of the Ragnar Group developers were brought before the examining magistrate of the Paris Justice Court at the end of a weeklong action. 

It also turned out that the ransomware infrastructure had been confiscated in the Netherlands, Germany, and Sweden. The data leak website associated with the ransomware had also been taken offline in Sweden as well. 

The Ragnar Locker ransomware group was one of the first big game-hunting ransomware groups to steal data in addition to encrypting files and threatening victims with ransom. The Ragnar Locker ransomware operation was not a ransomware-as-a-service (RaaS) operation, but rather an operation in collaboration with external penetration testers to gain first access to victims' networks, as opposed to many other ransomware groups. 

There was an announcement on Friday that at least one arrest had been made after the dark website was seized on Thursday, with at least one arrest being reported on Friday. As a result of the seized negotiation site now being seized by law enforcement, ransomware victims will now receive a message indicating that they are being assisted by law enforcement, even though no assistance has yet been provided for them. 

There was news that a 35-year-old Czech national who was arrested in France on October 16 under suspicion of being the group leader had been detained, and police in his country had searched his residence on suspicion of protecting his activities.

According to Ukrainian authorities, there was a search of a suspect's home in Kyiv and several devices and electronic media were taken from the residence of the suspect. The name of the suspect has not yet been released publicly.  

In late 2019, Ragnar Locker began operating as an affiliate of Maze or MountLocker. The company has been operating since then. There was no doubt that this group was one of the biggest groups in terms of attack volumes or money collected, but it was a significant threat and several critical infrastructure entities in several countries were penetrated by the group as a major threat, making it a priority for law enforcement. 

A central theme that emerges from the groups that are targeted by these major law enforcement campaigns is their tendency to become overly audacious in their attacks on sensitive critical infrastructure, such as power grids, water supply systems, and hospitals. While Ragnar Locker gained notoriety for its high-profile attacks on gaming company Capcom and liquor giant Campari, it is the attacks on entities like Energias de Portugal that truly propelled it up the priority ladder.  

A flash warning issued by the FBI in early 2022 revealed that Ragnar Locker had already breached the defences of 52 critical infrastructure companies across 10 different sectors in the United States up until that point in time. This alarming revelation highlights the scale and impact of Ragnar Locker's activities. 

This investigation was conducted by agents from the US FBI and the French Secret Service, along with representatives of Europol and INTERPOL. As a result of this investigation, two senior Ragnar Locker operatives were arrested, along with eight other officers from French and US intelligence agencies. 

There have been arrests and disruptions this week due to the investigation that has been ongoing for the past few days. Europol had supported the investigation from the very beginning, bringing together all the concerned nations to coordinate a coordinated action. 

During the preparation of the current steps, its cybercrime experts conducted 15 coordination meetings along with two week-long sprints. As a consequence of Europol's decision last week to establish a virtual command post for smooth cooperation among all entities involved in cybercrime, the company is also providing analysis, malware, forensic, and crypto-tracing assistance.  

This move by the government to bring down the Ragnar Locker ransomware group underlines the importance of international cooperation to combat cybercrimes. Law enforcement officials from different countries worked together to dismantle the infrastructure of the group and arrest its key members as part of this operation. 

The Ragnar Locker ransomware group was brought to an end by a remarkable display of international collaboration among law enforcement agencies. International cooperation has proven to be an effective method of safeguarding our digital environment in this particular operation.

The Insider Threat: Everest Cybercriminals Offering Cash for Remote Access

 


In a transition researchers consider to be a major improvement for cybercriminals who operate in the dark web, Everest ransomware has stepped up its efforts to direct employees into purchasing access to corporate networks directly from them. 

Earlier this week, Everest said in a post at the top of its dark web victim blog that it would pay a "good percentage" of the profits generated from successful attacks to anyone who assisted in assisting in Everest's initial hack. 

As a result of these commitments, the group is making an extra effort to be transparent regarding the nature of every operation, as well as maintaining confidentiality about the role each partner played in these operations. Specifically, Everest is interested in providing access to organizations located in the US, Canada, and Europe. 

The company would accept remote access to these organizations using a variety of methods, such as TeamViewer, AnyDesk, and RDP. Upon looking at the message, it is similar to the one it published in July. Around the same time, researchers suggested that the ransomware game might be dead in the water and the company was dropping the ransomware altogether. 

The IAB first became active in 2021, but activity has been rising since November 2022 with a greater level of IAB activity than that of previous years. It has become very commonplace for internationally coordinated gangs of ransomware gangs to be busted to avoid being the next target. Everest could aim to avoid becoming the next victim. 

Researchers say that BreachForums, which was closed earlier this year, may be trying to sell its access as part of a new business model, to take advantage of its fame as an established ransomware force as part of its campaign. According to researchers, around the same time it published its first message, it seemed to be indicating it might be exiting the ransomware game entirely. 

The message appears to be the same as the one it posted back in July. According to Searchlight Cyber, over the past few months, there have been several signs that the ransomware group was moving toward being an initial access broker (IAB), which is an "extremely rare" move. 

As of November 2022, it has shown increased IAB activity compared to the initial act of acting as an IAB that occurred in 2021. Ransomware criminals often hire IAB groups as a means of transferring access to organizations' networks, sometimes to more than one group at the same time, which makes it simpler for ransomware to be deployed. 

It's not completely understood why a ransomware group might move to the IAB rather than a ransomware group, resulting in a less lucrative business, and the reasons for this are not fully understood but have been speculated to include evading law enforcement in addition to losing members of the team. 

There is an increasing trend of international coordinated attacks by ransomware gangs that are becoming more and more common, and Everest may be trying to avoid becoming the next Hive or REvil. Researchers have indicated that BreachForums could also be trying to sell its access as part of a new business model to take advantage of its reputation as an established ransomware force. 

In the past few years, cybercriminal groups, such as LockBit, have adopted the tactic of exploiting disgruntled employees or otherwise rebellious employees, which is not new. In a survey conducted by Pulse and Bravura Security in 2022, 65 per cent of corporate executives were interviewed directly by ransomware criminals to help facilitate access to their employers' networks, according to a report by Pulse and Bravura Security. 

Promises of large payouts are frequently made to professionals who are willing to facilitate access for the thieves or even go as far as deploying the ransomware themselves. This tactic is used to entice individuals into participating in cybercrime activities. 

Interestingly, an investigation conducted by Abnormal Security in 2021 shed light on one specific case involving the Demonware gang. It was discovered that this group offered a staggering 40 per cent of the total proceeds from a successful attack as compensation for anyone who would deploy their ransomware. 

In an intriguing turn of events, the researchers at Abnormal Security were approached by someone claiming to be a member of the Demonware gang. This individual, who had adopted a fake persona, made an enticing offer of $1 million in Bitcoin. The catch? The researchers were expected to successfully ransom an organization for a whopping $2.5 million. It's fascinating to see how cybercriminals are willing to go to such lengths to entice others into their illegal activities.

MetaEncryptor Rebranded: LostTrust Ransomware Looms as a Fresh Cyber Threat

 


According to the latest reports, LostTrust is thought to be the rebranding of MetaEncryptor, which is using almost identical data leak sites and encryption methods as MetaEncryptor had used in the past. There was a cyber attack by the LostTrust group in March 2023, however, the site was not widely known until September, when the group began employing a data leak site to inform people about their attacks. 

Several suspicious sites listed at metaencryptor.com have been identified as being related to LostTrust ransomware due to the similarity of the data leak websites and Windows encryption programs. The cybersecurity researcher Stefano Favarato has discovered that two ransomware gangs are using the same template and bios on their websites, with the gangs touting the experience of their members having worked in network security for 15 years or more, and each trio promoting itself as network security specialists as well. 

MalwareHunterTeam points out that both LostTrust and MetaEncryptor were using the SFile2 ransomware encryptor as the basis to encrypt their files, and only slight differences were found between their ransom notes, notes names, embedded public keys, and stored encrypted file extensions. 

MetaEncryptor has Been Rebranded 


In August 2022, MetaEncryptor was launched, and through July 2023, twelve victims were added to the data leak website as a result of this ransomware infection. After this point, no new victims were added to the site. 

According to cybersecurity researcher Stefano Favarato, the 'LostTrust' gang has released a new data leak website this month, which uses the same template and bio as the one used by MetaEncryptor's data leak site created earlier this year. 

The researchers were also able to find that LostTrust and MetaEncryptor are virtually identical encryptors, with some minor differences due to the ransom notes, embedded public keys, the names of the ransom notes, and the encrypted file extensions that are used. 

According to MalwareHunterTeam, a cybersecurity researcher from BleepingComputer, the SFile2 ransomware encryptor is also the basis of the LostTrust and MetaEncryptor ransomware encryptors. A scan conducted by Intezer of the LostTrust and SFile encryptors shows a significant amount of code overlap between them, which further supports this relationship between them. 

There is a consensus among industry experts that LostTrust is a rebranding of MetaEncryptor, which can be attributed to the significant overlap between the two operators. It has been revealed that further analysis of the LostTrust encryption tool has revealed that during execution, several Windows services have been disabled, and several Microsoft Exchange services have been deactivated before encryption in order to prevent any additional attacks. 

Based on the ransom notes provided by the operation, members of the organization were once ethical hackers who became involved with cybercrime after being underpaid for their work.

An Encryption Algorithm Known as LostTrust


Using onlypath and enable-shares as command line arguments, you can install the encryptor without encrypting any network drives, and onlypath can also encrypt specific paths. A console window will open when you launch the encryptor, explaining what is going on with the encryption process at the moment. 

It is worth noting that the string 'METAENCRYPTING' is present in the encryptor, which indicates that it is a modified MetaEncryptor encryptor. The LostTrust application performs several pre-defined actions to ensure all files are encrypted upon execution. This includes disabling and stopping Windows services which contain the Firebird, MSSQL, SQL, Exchange, WSBEX, PostgreSQL, BACKP, tomcat, SBS, and SharePoint strings. 

As part of the encryption process, other Microsoft Exchange-related services will also be disabled and stopped by the encryptor. There will be an impending influx of ransom notes named !LostTrustEncoded.txt that will appear in every folder on the device and contain the threat actors introducing themselves as former white hat hackers who decided to switch to crime after being extremely low-paid. 

There is a unique link to the ransomware gang's Tor negotiation site within these ransom notes that provides information about what happened to the company's files and the ransomware gang's activities. There is no built-in feature on the negotiation site that allows company representatives to communicate with threat actors other than using a chat facility. 

It appears that the LostTrust ransomware resurfaced recently, a suspected rebrand of the MetaEncryptor gang. Both the ransomware's tactics and encryption methods are strikingly similar. Despite remaining relatively unknown until September, it appears as though this enigmatic group developed as ethical hackers who turned into cybercriminals for financial gain. Through the ransom notes, victims can communicate with the group through a Tor negotiation site, offering a unique link to connect with them.

Quid Pro Quo Attacks: Cyber Threat to Watch Out For

 

A threatening message appears out of nowhere. You owe money, or a loved one is in jeopardy, according to the sender's unknown claims. They threaten consequences unless you cough up the cash or disclose personal information.

To say the least, it's unsettling. These "quid pro quo" attacks appear to be on the rise as well. But what is a quid pro quo attack, and how can you avoid one? 

Explaining the Quid Pro Quo attack 

The Latin phrase "quid pro quo" alludes to a value exchange--receiving something in exchange for something else. A quid pro quo strategy has several forms in the context of attacks or scams:

Extortion: It occurs when an attacker gains access to or claims to have sensitive personal data such as images, messages, or browser history. They threaten to make the information public unless the victim pays a ransom. 

Social Engineering: The attacker creates a pressing situation, such as an emergency or a time-sensitive bill. They trick the victim into giving money or disclosing personal information immediately.

Bribery/presents: The hacker promises the victim money, presents, exclusive opportunities, or other incentives in exchange for sensitive data, obscene photos/videos, meetings, and so on. 

How quid pro quo attacks target victims 

There are several possible settings for quid pro quo attacks. In exchange for the user's login and password, attackers may impersonate someone from an internal or external IT department and promise to deliver a free virus scan to make the user's device operate more efficiently. An attacker could acquire access to the company's network and install malware even with this minimal information. 

The attackers can also target home-based employees who receive a call from a specific credit union advertising a low-interest credit card or refinance rate for XYZ firm. To claim the offer, the employee simply needs to enter their social security number, employee ID number, and birthday to validate their credit score. 

Most quid pro quo plans involve the attacker providing enough information to make the offer sound reasonable (and most people are looking for a good bargain), so the user delivers the information without considering the potential liabilities.

People impersonating government authorities (such as the Internal Revenue Service, Department of Motor Vehicles, or Social Security Administration) can also be employed in quid pro quo attacks. They may offer to settle a disagreement in exchange for the user's social security number or other personally identifiable information, allowing the perpetrator to steal the victim's identity.

Prevention tips

There are a lot of shady folks on the internet these days. Knowing how to defend yourself against quid pro quo attacks is therefore critical. 

First and foremost, vigilance is essential. Be careful of any random emails, calls, DMs, or other communications that make big offers or threats. Examine for telltale symptoms of a fraud, such as urgency, ambiguous details, spelling and grammar errors, and so on. 

Consider whether a trustworthy business or individual would contact out in this manner. The IRS will not reach out to you cold and demand quick payment, and Nigerian princes will not suddenly offer you money. It all comes down to weighing the likelihood of the situation. 

Speaking about calls, refrain from providing personal information to telemarketers. Your name and information will be known by official organisations like your bank. They won't randomly phone and ask you to confirm something. Hanging up and making a second call on a business line is considerably safer. 

The same is true for attachments and links. Move forward with great caution. Phishers are cunning; they make bogus emails that seem authentic. Therefore, before clicking a link, hover over it to see what the actual URL is. Verify if they correspond to the actual site. And be careful not to download malware by opening attachments from unknown senders. 

And, of course, never give money, gift cards, or sensitive information to strangers online for any reason. Legitimate help organisations will not cold mail you in this manner. Donate only to verified groups through the official website.

Last but not least, maintain your antivirus, firewalls, and devices up to date. This closes security weaknesses that hackers exploit. It's best to automate software updates wherever feasible so you don't have to think about it.

QWIXXRAT: A Fresh Windows RAT Emerges in the Threat Landscape

 

In early August 2023, the Uptycs Threat Research team uncovered the presence of a newly identified threat, the QwixxRAT, also referred to as the Telegram RAT. This malicious software was being promoted and distributed via platforms such as Telegram and Discord.

The QwixxRAT operates as a remote access trojan, capable of surreptitiously gathering sensitive information from targeted systems.

This ill-gotten data is then surreptitiously transmitted to the attacker's Telegram bot, granting them unauthorized access to the compromised user's confidential details. The process is facilitated by the threat actors who can manipulate and oversee the RAT's activities through the same Telegram bot.

“Once installed on the victim’s Windows platform machines, the RAT stealthily collects sensitive data, which is then sent to the attacker’s Telegram bot, providing them with unauthorized access to the victim’s sensitive information.”reads a new report published by security firm Uptycs.

“To avoid detection by antivirus software, the RAT employs command and control functionality through a Telegram bot. This allows the attacker to remotely control the RAT and manage its operations.” 

Experts have identified the QwixxRAT as a meticulously engineered threat, specifically crafted to extract a wide spectrum of sensitive data. Its repertoire includes the theft of browser histories, credit card particulars, screenshots, keystrokes, FTP credentials, messenger conversations, and data linked to the Steam platform.

Uptycs, the cybersecurity company behind the discovery, underscored that the QwixxRAT is available for purchase on the criminal market. Interested parties can acquire a weekly subscription for 150 rubles or opt for a lifetime subscription priced at 500 rubles. Additionally, a limited free version has been noted by the researchers.

Technically, the QwixxRAT is coded in C# and takes the form of a compiled binary, functioning as a 32-bit executable tailored for CPU operations. With a total of 19 distinct functions, the malware exhibits a diverse set of capabilities.

In order to evade scrutiny, the malware incorporates various anti-analysis features and evasion tactics. Notably, the RAT employs a sleep function to introduce delays, serving as a mechanism to detect potential debugging activities. Furthermore, the malicious code performs checks to ascertain if it is running within a sandbox or virtual environment.

The QwixxRAT establishes persistence by creating a scheduled task tied to a concealed file located at "C:\Users\Chrome\rat.exe". Additionally, the malware possesses a self-destruct mechanism that can be triggered for the C# program's termination.

A unique characteristic of the QwixxRAT is its incorporation of a clipper code, enabling the capture of data copied to the clipboard. This technique is adeptly employed to extract cryptocurrency wallet information pertaining to Monero, Ethereum, and Bitcoin.

The researchers have taken a proactive step by publishing a YARA detection rule tailored to identify this particular threat.

Following the JumpCloud Incident, Additional Malware was Discovered in the Npm Packages

 


There has been a supply chain attack against JumpCloud, an IT management company known for cryptocurrency products. This attack targets a small group of its clients. Two weeks after JumpCloud announced that it had been compromised, an investigation by ReversingLabs researchers has revealed that there has also been evidence of malicious npm packages connected to the same infrastructure that targets cryptocurrency providers as well. 

Over the past few months, researchers at ReversingLabs have discovered more than two dozen NPM packages that use form data to steal from business processes in a "coordinated supply chain attack." As a dependency installer, Node Package Manager can install dependencies for JavaScript and Node.js runtime environments. 

Designers were tricked into downloading malicious packages through typo-squatting, a subtle but intentional misspelling of popular software repositories, in the SolarWinds-style attack dubbed IconBurst. 

The researchers report that the supply chain attack was successful, as one malicious NPM package has been downloaded more than 17,000 times out of 100,000 possible downloads. Even though developers used these malicious packages as a launchpad for their attacks, the final targets they targeted were end users' data. 

There have been several additional npm packages discovered by ReversingLabs to be linked to the same malicious campaign. ReversingLabs Reverse Engineer, Karlo Zanki, says that one of the components uploaded to the npm project on July 11 has ties to a supply chain attack first identified by Phylum on June 23 that is regarded as a possible precursor to the JumpCloud attack. Phylum identified this attack as a possible precursor to the JumpCloud attack. The Phylum team has since published an additional blog post about this package, as well as other packages in bitcoin-api-node. 

A few days after the packages were posted on npm, all of them were removed from the repository - perhaps of their own accord. There could be a reason behind that, for example, to help reduce the likelihood of their malicious npm packages being detected once they are successful in getting them to be integrated into target applications or environments.  

The Popular NPM Packages are Type-Squatted


ReversingLabs have discovered that malicious NPM packages are being distributed by the threat actors as legitimate JavaScript libraries disguised as malicious NPM packages. It is believed that they exploited the typo-squatting technique, which uses common misspellings in fair packages to trick developers into installing malware-infected libraries. The attackers targeted high-traffic NPM packages, such as the popular Umbrellajs JavaScript library for manipulating document object models (DOM), which was used by most users. 

As Zanki reports, the npm-audit [dot] com domain is being used for communication between the btc-api-node package and the npm site. As part of a GitHub alert issued on July 18, a domain was named that was used as part of the command and control infrastructure for malicious packages used in the JumpCloud attack, which was identified as a part of the command and control infrastructure for those malicious packages. GitHub warned of a low-volume social engineering attack targeting the personal accounts of employees of tech companies. 

GitHub has identified both the npmaudit.com domain as an indication of compromise (IOC) as well as domains specifically identified as indicators of compromise by Phylum in its June alert as malicious domains. 

There seems to be a mixture of high-touch and low-touch campaigns in the supply chain attacks being discussed, just like the Operation Brainleeches npm compromise reported a few weeks ago. The attackers in some cases made very hardly any effort to make it appear as if the malicious packages that they inserted were legitimate. Nevertheless, other cases have happened where attackers put more effort into convincing would-be developers that the malicious packages looked more trustworthy to them than actual malicious packages. 

As part of Zanki's efforts, he modified the package metadata and added legitimate npm user accounts to the package authorship for the package(s), he explained.  Before this posting, the Bitcoin API Node package btc-api-node was no longer available to install. 

The researchers at ReversingLabs, however, already concluded that with this package still available, it had a lot in common with a legitimate npm module called bitfinex-api-node, which as described by its developer is a reference implementation of the Bitfinex API for Node. JS. With this API, users can interact with some of the Bitcoin exchanges that offer services through Bitfinex.   

Upon execution of the BTC-API-node package, the post-install script starts index.js via the BTC-API-node package. There are values in the index.js file that are encoded in B64, so the values are encrypted. It sets environment variables to be ignored during SSL/TLS verification on a system running the package. 

According to Phylum's analysis of the subject matter, that could be an attempt to force HTTP requests to be made within corporate networks that have implemented their root certificates. This could be done by using proxy servers instead of relying on external public key infrastructure. 

This package also creates a folder on the system where it is installed. Once the folder is created, a file will be downloaded from hxxps://npmaudit.com/api/v4/init and stored in that directory. In the package named .electron, the folder names seem to vary depending on the package, however, the directory and subdirectory within the package is .electron. 

It is a file that acts as a token on a compromised system that signifies the presence of stage 2 malware on the compromised system and that the system is open to receiving the malware without being detected (Phylum has provided a list of them in their analysis.)  

Campaign to exfiltrate data aggressively


It has been found that malicious NPM packages are meant to harvest sensitive information from mobile applications and websites embedded with forms that collect sensitive data. To begin with, the threat actors opted to follow a conservative approach when it came to the exfiltration of the data from web pages. The NPM packages that are injected with malicious code have become more aggressively aggressive in their approach to extracting data. 

ReversingLabs warns that most software development companies are unable to detect unauthorized code hidden within open-source libraries. It was as a result of this investigation that ReversingLabs researchers reported to the NPM security team to remove the malicious NPM repositories. 

This ensures the software supply chain remains secure. To further assist organizations to identify possible malicious packages in their applications, the authors have also published a list of indicators of compromise (IoCs), including exfiltration domains, to be used to identify instances of compromise. 

Taking Action in response to the Threat


JumpCloud's analysis shows that there was only a small scope of the supply chain attack on that organization - just a small number of accounts that were associated with the cryptocurrency industry, by JumpCloud's attribution - relative to the scope of the attack.   Although the attack lasted longer than the last time, it suggests that other organizations could have been targeted. 

This is due to the more significant number of malicious packages and the extended timeline. Furthermore, the malicious actors responsible for the attacks have taken steps to minimize exposure to the public. This includes quickly removing the offending packages from the NPM repository.
