Weak Links in Healthcare Infrastructure Fuel Cyberattacks

 


Increasingly, cybercriminals are exploiting systemic vulnerabilities in order to target the healthcare sector as one of the most frequently attacked and vulnerable targets in modern cybersecurity, with attacks growing both in volume and sophistication. These risks go well beyond the theft of personal information - they directly threaten the integrity and confidentiality of critical medical services and patient records, as well as the stability of healthcare operations as a whole. 

There has been an increase in threat actors targeting hospitals and medical institutions due to the outdated infrastructure and limited cybersecurity resources they often have. Threat actors are targeting these organisations to exploit sensitive health information and disrupt healthcare delivery for financial or political gain. The alarming trend reveals that there is an urgent and critical security issue looming within the healthcare industry that needs to be addressed immediately. 

Such breaches have the potential to have catastrophic consequences, from halting life-saving treatments due to system failures to eroding patients' trust in healthcare providers. Considering the rapid pace at which the digital transformation is taking place in healthcare, it is important that the sector remains committed to robust cybersecurity strategies so as to safeguard the welfare of its patients and ensure the resilience of essential medical services in the future. 

BlackCat, also referred to as ALPHV, is at the centre of a recent significant cybersecurity incident. In recent months, it has gained prominence as a highly organised, sophisticated ransomware group that has been linked to the high-profile attack on Change Healthcare. As a result of the infiltration of the organisation's IT infrastructure and the theft of highly sensitive healthcare data by the group, the group has claimed responsibility for obtaining six terabytes of data.

As a result of this breach, not only did it send shockwaves throughout the healthcare sector, but it also highlighted the devastating power of modern ransomware when targeting critical systems. It has been reported that the attack was triggered by known vulnerabilities in ConnectWise's ScreenConnect remote access application, a tool that is frequently employed in many industries, including healthcare, as a remote access tool. 

Having this connection has given rise to more concern about the broader cybersecurity risks posed by third-party vendors as well as software providers, showing that even if one compromised application is compromised, it can lead to widespread data theft and operational disruption as a result. This incident has served as a stark reminder that digital ecosystems in healthcare are fragile and interconnected, with a breach in one component leading to cascading effects across the entire healthcare service network. 

There is a growing concern in the healthcare sector that, as investigations continue and new details emerge, healthcare providers are still on high alert, coping with the aftermath of the attack as well as the imperative necessity of strengthening their defensive infrastructure in order to prevent similar intrusions in the future. As one of the most frequently targeted sectors of the economy by cybercriminals, healthcare continues to be one of the most highly sensitive data centres in the world. 

It is important to note that even though industry leaders often fail to rank cybersecurity as one of their top challenges, Mike Fuhrman, CEO of Omega Systems, pointed out that despite this growing concern, there are already significant consequences resulting from insufficient cyber risk management, including putting patient safety at risk, disrupting care delivery, and making compliance with regulations even more difficult. Even though perceived priorities are not aligned with actual vulnerabilities, this misalignment poses an increasing and significant risk for the entire healthcare system. 

Fuhrman stressed the necessity of improving visibility into security threats and organisational readiness, as well as increasing cybersecurity resources, to bridge this gap. As long as healthcare organisations fail to take proactive and comprehensive steps to ensure cyber resilience, they may continue to experience setbacks that are both detrimental to operational continuity as well as eroding public trust, as well as putting patient safety at risk. 

As cybersecurity has become more and more important to the leadership, it has never been more important to elevate it from a back-office issue to an imperative. As a result of the growing number of cyberattacks targeting the healthcare sector in the past few years, the scale and frequency of these attacks have reached alarming levels.

According to the Office for Civil Rights (OCR), the number of security breaches reported by the healthcare industry between 2018 and 2023 has increased by a staggering 239%. Over the same period, there was a 278% increase in ransomware incidents, which suggests that cybercriminals are increasingly looking for disruptive, extortion-based attacks against healthcare providers as a means of extorting money. 

There is a likelihood that nearly 67% of healthcare organisations will have been attacked by ransomware at some point shortly, which indicates that such threats are no longer isolated events but rather a persistent and widespread threat. According to experts within the health care industry, one of the primary contributing factors to this vulnerability is the lack of preparedness at all levels. In fact, 37% of healthcare organisations do not have an incident response plan in place, leaving them dangerously vulnerable to ever-evolving cyberattacks. 

Health care institutions are appealing to malicious actors because they manage a huge amount of valuable data. Cybercriminals and even nation-state threat actors are gaining an increasing level of interest in electronic health records (EHRs), which contain comprehensive information about patient health, financial health, and medical history.

As a result of outdated cybersecurity protocols, legacy IT infrastructure, and operational pressures of high-stress environments, these records are frequently inadequately protected due to the likelihood that human error will occur more often. These factors together create an ideal storm for exploitation, making the healthcare industry a very vulnerable and frequently targeted industry in today's digital threat landscape.

Despite the growing frequency and complexity of cyberattacks, healthcare organisations face a critical crossroads as 2025 unfolds. Patient safety, data security, and regulatory compliance all intersect at the same time, resulting in a crucial crossroads more than ever before. Enhancing cyber resilience has become a strategic priority and a fundamental requirement, not just a strategic priority. 

Healthcare institutions must proactively adopt forward-looking security practices and technologies to secure sensitive patient data and ensure continuous care delivery. As a key trend influencing the healthcare cybersecurity landscape, zero-trust architectures are a growing trend that challenges traditional security models by requiring all users and devices to be verified before they are allowed access. 

In a hyperconnected digital environment where cyber threats exploit even the most subtle of system weaknesses, a model such as this is becoming increasingly important. IoT devices are becoming increasingly popular, and many of them were not originally designed with cybersecurity in mind, so we must secure them as soon as possible. Providing robust protections for these devices will be crucial if we are to reduce the attack surfaces of these devices. 

AI has been rapidly integrated into healthcare, and it has brought new benefits as well as new vulnerabilities to the healthcare sector. In order for organisations to meet emerging risks and ensure a responsible deployment, they must now develop AI-specific safety frameworks. Meanwhile, the challenge of dealing with technological sprawl, an increasingly fragmented IT environment with disparate security tools, calls for a more unified, centralised cybersecurity management approach.

A good way to prepare for 2025 is to install core security measures like multi-factor authentication, strong firewalls, and data backups, as well as advanced measures like endpoint detection and response (EDR), segmentation of the network, and real-time AI threat monitoring. In addition to strengthening third-party risk management, it will also be imperative to adhere to global compliance standards like HIPAA and GDPR.

There is only one way to protect both healthcare infrastructure and the lives that are dependent on it in this ever-evolving threat landscape, and that is by implementing a comprehensive, proactive, and adaptive cybersecurity strategy. Healthcare organisations must take proactive measures rather than reactive measures and adopt a forward-looking mindset so they can successfully navigate the increasing cybersecurity storm. 

Embedding cybersecurity into healthcare operations' DNA is the path to ensuring patient safety, operational resilience, and institutional trust in healthcare organisations, not treating it as a standalone IT concern, but as a critical pillar of patient safety, operational resilience, and institutional trust in healthcare organisations.

To achieve this, leadership must take the initiative to champion security from the boardroom level, integrate threat intelligence into strategic planning, and invest in people and technology that will be able to anticipate, detect, and neutralise emerging threats before they become a major issue. As part of the process of fostering cyber maturity, it is also essential to cultivate a culture of shared responsibility among all stakeholders, ranging from clinicians to administrative personnel to third-party vendors, who understand the importance of keeping data and systems secure. 

Training on cybersecurity hygiene, cross-functional collaboration, and continuous vulnerability assessment must become standard operating procedures in the healthcare industry. As attackers become more sophisticated and bold, the costs of inaction do not stop at regulatory fines or reputational damage. Rather, inaction may mean interruptions of care, delays in treatments, and the risk to human life. 

Only organisations that recognise cybersecurity as a strategic imperative will be in the best position to deliver uninterrupted, trustworthy, and secure care in an age when digital transformation is accelerating. This is a sector that is built on the pillars of trust, a sector that offers life-saving services, which does not allow for room for compromise. They have to act decisively, investing today in the defensive measures that will ensure the future of their industry.

Chinese Data Breach Data Leak data security Data Surveillance database Database Breach Personal Information protecting sensitive data

Massive Data Leak Exposes Billions of Records in Suspected Chinese Surveillance Database

 

Cybersecurity experts have uncovered a massive trove of sensitive information left exposed online, potentially placing millions of individuals at significant risk. The discovery, made by researchers from Cybernews in collaboration with SecurityDiscovery.com, revealed an unsecured database totaling 631 gigabytes—containing an estimated four billion individual records. 

The open instance, which lacked any form of password protection, was quickly taken offline once the exposure was reported, but experts remain unsure about how long it had remained publicly accessible. The data, according to the investigation, appears to primarily concern Chinese citizens and users, with entries collected from various platforms and sources. 

Cybernews researchers believe this is not a random collection, but rather a systematically curated database. They described it as a tool capable of constructing detailed behavioral, social, and financial profiles of nearly any individual included in the records. The structured and diverse nature of the data has led analysts to suspect that the repository may have been created as part of a broader surveillance or profiling initiative. 

Among the most alarming elements of the database is the presence of extensive personally identifiable information (PII). The exposed details include full names, birth dates, phone numbers, financial records, bank card data, savings balances, debt figures, and personal spending patterns. Such information opens the door to a wide range of malicious activities—ranging from identity theft and financial fraud to blackmail and sophisticated social engineering attacks. 

A large portion of the exposed records is believed to originate from WeChat, the popular Chinese messaging app, which accounts for over 805 million entries. Another 780 million records relate to residential data tied to specific geographic locations. Meanwhile, a third major portion of the database labeled “bank” contains around 630 million records of financial and sensitive personal data. 

If confirmed, the scale of this leak could surpass even the National Public Data breach, one of the most significant data security incidents in recent memory. Experts are particularly troubled by the implications of a centralized data cache of this magnitude—especially one that may have been used for state-level surveillance or unauthorized commercial data enrichment. 

While the server hosting the information has been taken offline, the potential damage from such an exposure may already be done. Investigators continue to analyze the breach to determine its full impact and whether any malicious actors accessed the data while it was left unsecured.

Kettering Health Ransomware Attack Linked to Interlock Group

 

Kettering Health, a prominent healthcare network based in Ohio, is still grappling with the aftermath of a disruptive ransomware attack that forced the organization to shut down its computer systems. The cyberattack, which occurred in mid-May 2025, affected operations across its hospitals, clinics, and medical centers. Now, two weeks later, the ransomware gang Interlock has officially taken responsibility for the breach, claiming to have exfiltrated more than 940 gigabytes of data.  

Interlock, an emerging cybercriminal group active since September 2024, has increasingly focused on targeting U.S.-based healthcare providers. When CNN first reported on the incident on May 20, Interlock had not yet confirmed its role, suggesting that ransom negotiations may have been in progress. With the group now openly taking credit and releasing some of the stolen data on its dark web site, it appears those negotiations either failed or stalled. 

Kettering Health has maintained a firm position that they are against paying ransoms. John Weimer, senior vice president of emergency operations, previously stated that no ransom had been paid. Despite this, the data breach appears extensive. Information shared by Interlock indicates that sensitive files were accessed, including private patient records and internal documents. Patient information such as names, identification numbers, medical histories, medications, and mental health notes were among the compromised data. 

The breach also impacted employee data, with files from shared network drives also exposed. One particularly concerning element involves files tied to Kettering Health’s in-house police department. Some documents reportedly include background checks, polygraph results, and personally identifiable details of law enforcement staff—raising serious privacy and safety concerns. In a recent public update, Kettering Health announced a key development in its recovery process. 

The organization confirmed it had restored core functionalities of its electronic health record (EHR) system, which is provided by healthcare technology firm Epic. Officials described this restoration as a significant step toward resuming normal operations, allowing teams to access patient records, coordinate care, and communicate effectively across departments once again. The full scope of the breach and the long-term consequences for affected individuals still remains uncertain. 

Meanwhile, Kettering Health has yet to comment on whether Interlock’s claims are fully accurate. The healthcare system is working closely with cybersecurity professionals and law enforcement agencies to assess the extent of the intrusion and prevent further damage.

Lee Enterprises Ransomware Attack Exposes Data of 40,000 Individuals

 

Lee Enterprises, a major U.S. news publisher, is alerting nearly 40,000 individuals about a data breach following a ransomware attack that took place in early February 2025. The company, which owns and operates 77 daily newspapers and hundreds of weekly and special-interest publications across 26 states, reported that the cyberattack resulted in the theft of personal information belonging to thousands of people. 

Details of the breach were revealed in a recent disclosure to the Maine Attorney General’s office. According to the company, the attackers gained unauthorized access to internal documents on February 3, 2025. These files contained combinations of personal identifiers such as names, Social Security numbers, driver’s license details, bank account information, medical data, and health insurance policy numbers. The security incident caused widespread operational disruptions. 

Following the attack, Lee Enterprises was forced to shut down multiple parts of its IT infrastructure, impacting both the printing and delivery of its newspapers. Several internal tools and systems became inaccessible, including virtual private networks and cloud storage services, complicating daily workflows across its local newsrooms. In a filing with the U.S. Securities and Exchange Commission shortly after the breach, the company confirmed that critical systems had been encrypted and that a portion of its data had been copied by the attackers. 

The source of the attack is yet to be identified, a group known as Qilin has allegedly claimed responsibility near the end of February. The group alleged it had stolen over 120,000 internal files, totaling 350 gigabytes, and threatened to publish the material unless their demands were met. Soon after, Qilin posted a sample of the stolen data to a dark web leak site, which included scans of government-issued IDs, financial spreadsheets, contracts, and other confidential records. The group also listed Lee Enterprises as a victim on its public-facing extortion portal. 

When asked about the authenticity of the leaked data, a spokesperson for Lee Enterprises stated the company was aware of the claims and was actively investigating. This is not the first cybersecurity issue Lee Enterprises has faced. The company’s network was previously targeted by foreign actors during the lead-up to the 2020 U.S. presidential election, where hackers from Iran allegedly attempted to use compromised media outlets to spread disinformation. 

The ransomware attack highlights ongoing threats facing media companies, especially those handling high volumes of personal and financial data. As Lee Enterprises continues its recovery and legal steps, the incident serves as a reminder of the need for robust digital defenses in today’s information-driven landscape.

Zero-Day Flaw in Chrome and Chromium Puts Windows and Linux Users at Data Risk

 

A newly revealed zero-day vulnerability identified as CVE-2025-4664 has triggered serious concerns for billions of Google Chrome and Chromium users. Security experts have warned that this flaw, which affects both Windows and Linux platforms, could be exploited to leak sensitive cross-origin data such as OAuth tokens and session identifiers—all without requiring any user action.  

The vulnerability has been discovered within the Loader component of Chrome and Chromium browsers. It is linked to how these browsers interpret the Link HTTP header for sub-resource requests such as images or scripts. While most mainstream browsers follow strict guidelines for handling such requests, Chrome’s unique behavior stands out. It continues to respect the referrer-policy directive even when loading sub-resources, which can unintentionally expose sensitive information. 

This default behavior can be manipulated by attackers. A malicious site could inject a loose policy like “unsafe-url,” which then forces the browser to reveal complete URLs—including potentially sensitive credentials or session data—to third-party servers. This results in a severe breach of user privacy and circumvents traditional browser security measures. Cybersecurity firm Wazuh has stated that their Vulnerability Detection module can identify and address this specific flaw. 

The module leverages information from their Cyber Threat Intelligence (CTI) service to monitor browser versions and trigger alerts when vulnerable builds are detected. In controlled testing using Wazuh OVA 4.12.0, researchers were able to scan systems running Windows 11 and Debian 11 to determine if they were running affected versions of Chrome or Chromium. According to Wazuh’s platform, users can search for the vulnerability by querying CVE-2025-4664. If vulnerable software is found, the module changes the system status from “Active” to “Solved” after the necessary fixes are applied, helping administrators track progress in real time. 

In response to the discovery, Google has issued an emergency patch for Chrome users on Windows and Gentoo Linux. It is strongly recommended that users on these operating systems update their browsers immediately to avoid exposure. However, users on Debian 11 who rely on Chromium remain at risk, as no updated version has been released for that platform. All Chromium builds up to version 120.0.6099.224 are still considered vulnerable. Until a patch is available, security professionals advise uninstalling Chromium on affected Debian systems as a precautionary measure. 

While these immediate actions are important, experts caution that relying solely on browser updates is not a comprehensive defense. The broader cybersecurity strategy must include the use of endpoint protection platforms, anti-malware systems, and modern antivirus tools. These security layers can help detect and neutralize threats that slip past browser-based defenses and provide a stronger safety net for users and enterprises alike. 

As browser-based zero-day threats continue to emerge, users must remain vigilant. Rapid patching combined with proactive cybersecurity tools offers the best chance of mitigating risks and maintaining a secure browsing environment.

Critical Infrastructure data security malware Play PlayCrypt Playgroup Ransomware

FBI Alert: Play Ransomware Attacks 900 Organizations

FBI Alert: Play Ransomware Attacks 900 Victims

In a recent joint cybersecurity advisory released with its Australian partners, the FBI announced that the Play ransomware group has attacked over 900 organizations since May 2025. “As of May 2025, FBI was aware of approximately 900 affected entities allegedly exploited by the ransomware actors,” the FBI said. 

Triple growth in three years

The number has tripled; in 2023, the figure was 300. This highlights the group’s rapid growth of attacking capabilities and compromise of new flaws.

Since 2022, the Playgroup, aka Playcrypt, has launched attacks across Europe, North America, and South America. The victims are diverse, ranging from MNCs to public sector agencies to areas of critical infrastructure. 

The Play ransomware differs due to its strategic use of manual-coded malware for each compromise. The constant configuration of attacks and retooling increases the group’s efficiency by helping it avoid getting caught. 

In a few cases, the group has strengthened attack tactics by contacting victims directly and asking for ransom for not leaking their data. 

Members of the infamous cybercrime syndicate have also compromised various newly found flaws (CVE-2024-57726, CVE-2024-57727, and CVE-2024-57728) in remote monitoring and management software, deploying them as entry points for deeper penetration to compromise systems. In one incident, threat actors backdoored systems and used Sliver beacons, building the foundation for future ransomware attacks. 

Play follows a unique approach

Differing from other gangs, Play uses direct email communication instead of the Dark Web negotiation. 

Play extracts sensitive data and uses it for extortion, and also uses a proprietary tool to escape shadow copy protections in data thefts. Some high-profile targets include the City of Oakland, Dallas County, and Krispy Kreme. 

How to stay safe?

A sound understanding of ransomware groups and good cyber hygiene is a must to prevent ransomware attacks, specialized tools, however, can boost your defenses. 

The joint advisory recommends security teams to keep their systems updates to prevent exploit of unpatched vulnerabilities. They are also advised to use two-factor authentication (2FA) throughout all services. Organizations should keep offline data backups and make and test a recovery drill as part of their security practices.

Massive Cyberattack Disrupts KiranaPro’s Operations, Erases Servers and User Data


KiranaPro, a voice-powered quick commerce startup connected with India’s Open Network for Digital Commerce (ONDC), has been hit by a devastating cyberattack that completely crippled its backend infrastructure. The breach, which occurred over the span of May 24–25, led to the deletion of key servers and customer data, effectively halting all order processing on the platform. Despite the app still being live, it is currently non-functional, unable to serve users or fulfill orders. 


Company CEO Deepak Ravindran confirmed the attack, revealing that both their Amazon Web Services (AWS) and GitHub systems had been compromised. As a result, all cloud-based virtual machines were erased, along with personally identifiable information such as customer names, payment details, and delivery addresses. The breach was only discovered on May 26, when the team found themselves locked out of AWS’s root account. Chief Technology Officer Saurav Kumar explained that while they retained access through IAM (Identity and Access Management), the primary cloud environment had already been dismantled. 

Investigations suggest that the initial access may have been gained through an account associated with a former team member, although the company has yet to confirm the source of the breach. To complicate matters, the team’s multi-factor authentication (MFA), powered by Google Authenticator, failed during recovery attempts—raising questions about whether the attackers had also tampered with MFA settings. 

Founded in late 2024, KiranaPro operates across 50 Indian cities and allows customers to order groceries from local kirana shops using voice commands in multiple languages including Hindi, Tamil, Malayalam, and English. Before the cyberattack, the platform served approximately 2,000 orders daily from a user base of over 55,000 and was preparing for a major rollout to double its footprint across 100 cities. 

Following the breach, KiranaPro has contacted GitHub for assistance in identifying IP addresses linked to the intrusion and has initiated legal action against ex-employees accused of withholding account credentials. However, no final evidence has been released to the public about the precise origin or nature of the attack. 

The startup, backed by notable investors such as Blume Ventures, Snow Leopard Ventures, and TurboStart, had recently made headlines for acquiring AR startup Likeo in a $1 million stock-based deal. High-profile individual investors include Olympic medalist P.V. Sindhu and Boston Consulting Group’s Vikas Taneja. 

Speaking recently to The Indian Dream Magazine, Ravindran had laid out ambitious plans to turn India’s millions of kirana stores into a tech-enabled delivery network powered by voice AI and ONDC. International expansion, starting with Dubai, was also on the horizon—plans now put on hold due to this security incident. 

This breach underscores how even tech-forward startups are vulnerable when cybersecurity governance doesn’t keep pace with scale. As KiranaPro works to recover, the incident serves as a wake-up call for cloud-native businesses managing sensitive data.

Advanced Social Engineering Cyber Attacks cybercriminal group data security FBI FBI cybersecurity advisory Law Firms Luna Moth phishing techniques ransomware attacks Ransomwares

FBI Warns of Silent Ransom Group Using Phishing and Vishing to Target U.S. Law Firms

 

The FBI has issued a warning about a sophisticated cybercriminal group known as the Silent Ransom Group (SRG), also referred to by aliases like Luna Moth, Chatty Spider, and UNC3753. This group has been actively targeting U.S.-based law firms and related organizations through advanced phishing techniques and social engineering scams. The group, which has been operational since 2022, is known for using deceptive communication methods to gain unauthorized access to corporate systems and extract sensitive legal data for ransom demands. In the past, SRG’s activities spanned across industries such as healthcare and insurance. 

However, since the spring of 2023, its focus has shifted to legal entities, likely because of the highly confidential nature of the data managed by law firms. The group commonly uses a method called callback phishing, also known as reverse vishing. In this approach, victims receive emails that appear to originate from reputable companies and warn them of small charges for fake subscriptions. The emails prompt users to call a phone number to cancel the subscription. During these calls, victims are instructed to download remote access software under the guise of resolving the issue. Once the software is installed, SRG gains control of the victim’s device, searches for valuable data, and uses it to demand ransom.  

In March 2025, SRG has adapted their strategy to include voice phishing or vishing. In this new approach, the attackers call employees directly, posing as internal IT staff. These fraudulent callers attempt to convince their targets to join remote access sessions, often under the pretext of performing necessary overnight maintenance. Once inside the system, the attackers move swiftly to locate and exfiltrate data using tools like WinSCP or a disguised version of Rclone. Notably, SRG does not prioritize escalating privileges, instead focusing on immediate data theft. The FBI noted that these voice phishing methods have already resulted in multiple successful breaches. 

SRG reportedly continues to apply pressure during ransom negotiations by making follow-up calls to victim organizations. While the group does maintain a public site for releasing stolen data, its use of this platform is inconsistent, and it does not always follow through on threats to leak information. A significant concern surrounding these attacks is the difficulty in detection. SRG uses legitimate system management and remote access tools, which are often overlooked by traditional antivirus software. The FBI advises organizations to remain vigilant, particularly if there are unexplained downloads of programs such as AnyDesk, Zoho Assist, or Splashtop, or if staff receive unexpected calls from alleged IT personnel. 

In response, the FBI urges companies to bolster cybersecurity training, establish clear protocols for authenticating internal IT requests, and enforce two-factor authentication across all employee accounts. Victims of SRG attacks are encouraged to share any information that might assist in ongoing investigations, including ransom communications, caller details, and cryptocurrency wallet data.

WhatsApp Image Scam Uses Steganography to Steal User Data and Money

 

With over three billion users globally, including around 500 million in India, WhatsApp has become one of the most widely used communication platforms. While this immense popularity makes it convenient for users to stay connected, it also provides fertile ground for cybercriminals to launch increasingly sophisticated scams. 

A recent alarming trend involves the use of steganography—a technique for hiding malicious code inside images—enabling attackers to compromise user devices and steal sensitive data. A case from Jabalpur, Madhya Pradesh, brought this threat into the spotlight. A 28-year-old man reportedly lost close to ₹2 lakh after downloading a seemingly harmless image received via WhatsApp. The image, however, was embedded with malware that secretly installed itself on his phone. 

This new approach is particularly concerning because the file looked completely normal and harmless to the user. Unlike traditional scams involving suspicious links or messages, this method exploits a far subtler form of cyberattack. Steganography is the practice of embedding hidden information inside media files such as images, videos, or audio. In this scam, cybercriminals embed malicious code into the least significant bits of image data or in the file’s metadata—areas that do not impact the visible quality of the image but can carry executable instructions. These altered files are then distributed via WhatsApp, often as forwarded messages. 

When a recipient downloads or opens the file, the embedded malware activates and begins to infiltrate the device. Once installed, the malware can harvest a wide range of personal data. It may extract saved passwords, intercept one-time passwords, and even facilitate unauthorized financial transactions. What makes this form of attack more dangerous than typical phishing attempts is its stealth. Because the malware is hidden within legitimate-looking files, it often bypasses detection by standard antivirus software, especially those designed for consumer use. Detecting and analyzing such threats typically requires specialized forensic tools and advanced behavioral monitoring. 

In the Jabalpur case, after downloading the infected image, the malware gained control over the victim’s device, accessed his banking credentials, and enabled unauthorized fund transfers. Experts warn that this method could be replicated on a much larger scale, especially if users remain unaware of the risks posed by media files. 

As platforms like WhatsApp continue working to enhance security, users must remain cautious and avoid downloading media from unfamiliar sources. In today’s digital age, even an innocent-looking image can become a tool for cyber theft.

Google’s AI Virtual Try-On Tool Redefines Online Shopping Experience

 

At the latest Google I/O developers conference, the tech giant introduced an unexpected innovation in online shopping: an AI-powered virtual try-on tool. This new feature lets users upload a photo of themselves and see how clothing items would appear on their body. By merging the image of the user with that of the garment, Google’s custom-built image generation model creates a realistic simulation of the outfit on the individual. 

While the concept seems simple, the underlying AI technology is advanced. In a live demonstration, the tool appeared to function seamlessly. The feature is now available in the United States and is part of Google’s broader efforts to enhance the online shopping experience through AI integration. It’s particularly useful for people who often struggle to visualize how clothing will look on their body compared to how it appears on models.  

However, the rollout of this tool raised valid questions about user privacy. AI systems that involve personal images often come with concerns over data usage. Addressing these worries, a Google representative clarified that uploaded photos are used exclusively for the try-on experience. The images are not stored for AI training, are not shared with other services or third parties, and users can delete or update their photos at any time. This level of privacy protection is notable in an industry where user data is typically leveraged to improve algorithms. 

Given Google’s ongoing development of AI-driven tools, some expected the company to utilize this photo data for model training. Instead, the commitment to user privacy in this case suggests a more responsible approach. Virtual fitting technology isn’t entirely new. Retail and tech companies have been exploring similar ideas for years. Amazon, for instance, has experimented with AI tools in its fashion division. Google, however, claims its new tool offers a more in-depth understanding of diverse body types. 

During the presentation, Vidhya Srinivasan, Google’s VP of ads and commerce, emphasized the system’s goal of accommodating different shapes and sizes more effectively. Past AI image tools have faced criticism for lacking diversity and realism. It’s unclear whether Google’s new tool will be more reliable across the board. Nevertheless, their assurance that user images won’t be used to train models helps build trust. 

Although the virtual preview may not always perfectly reflect real-life appearances, this development points to a promising direction for AI in retail. If successful, it could improve customer satisfaction, reduce returns, and make online shopping a more personalized experience.

Brushing Scam Targets Amazon Customers with Unsolicited Packages and Hidden Cyber Threats

 

Ray Simmons was confused when he received an unexpected Amazon package containing beet chews. Initially, he thought it might be a joke from someone encouraging him to eat healthier. However, it turned out to be part of a broader scam known as “brushing,” where consumers receive unsolicited deliveries from online sellers attempting to manipulate product ratings and reviews. 

Brushing scams involve third-party sellers who send low-value goods to individuals whose names and addresses are often scraped from publicly available online sources. After the product is delivered, scammers use the recipient’s identity or create a fake account that resembles the recipient to leave positive reviews. These fake reviews can artificially boost a product’s credibility, helping it rank higher in search results and increasing sales. 

While receiving a free item might seem harmless, the scam carries hidden dangers. The U.S. Postal Inspection Service (USPIS) warns that these incidents indicate misuse of personal information. Even more concerning is the potential for packages to include QR codes, which might direct recipients to malicious websites. Scanning such codes can result in the installation of malware or the theft of personal data. 

The scam is a reminder that personal data is often accessible and can be exploited without a consumer’s knowledge. USPIS stresses the importance of not interacting with suspicious elements included in unsolicited packages. Inspector David Gealey noted that even though these items may appear insignificant, they are a signal that someone has unauthorized access to your personal information. 

Fortunately, the package Simmons received did not include a QR code. Nonetheless, he took immediate action by checking his Amazon and banking accounts for any signs of unauthorized access. This kind of vigilance is exactly what USPIS recommends for anyone in a similar situation. 

Authorities advise that recipients of such packages should not scan any QR codes or click on any related links. They also emphasize that there is no obligation to return unsolicited items. Instead, consumers should monitor their financial and e-commerce accounts for any suspicious activity and report the incident to local law enforcement, USPIS, or the Federal Trade Commission.  

Though brushing scams may appear to be minor nuisances, they reflect deeper issues related to data privacy and cyber fraud. Staying informed and cautious can help consumers protect themselves from further harm and support efforts to hold malicious actors accountable.

Cyberattack Forces Nucor to Halt Some Operations Amid Ongoing Investigation

 

Nucor, the largest steel manufacturer and recycler in North America, has disclosed a cybersecurity incident that forced the company to temporarily shut down some of its production operations. The Charlotte, North Carolina-based firm confirmed the event in a recent 8-K filing with the U.S. Securities and Exchange Commission (SEC), citing unauthorized third-party access to certain information technology systems. The breach prompted the company to activate its incident response plan. 

As a precautionary measure, Nucor took potentially affected systems offline, halted operations at undisclosed locations, and implemented containment and recovery procedures. The exact nature of the cyberattack has not been revealed, but the move to suspend operations has raised concerns over the potential severity of the incident. “Out of an abundance of caution,” the company stated, some facilities paused operations temporarily, though it did not identify which of its roughly 300 locations across the U.S., Canada, and Mexico were affected. 

Nucor emphasized that it is working to restore operations and resume full functionality as swiftly and safely as possible. The incident comes at a time when large manufacturers are increasingly targeted by cybercriminals aiming to exploit critical infrastructure for financial gain, intellectual property theft, or even geopolitical motives. Industry experts suggest that the operational disruption and limited communication from affected sites point toward a potential ransomware attack, although no group has claimed responsibility so far. 

In Q1 2025 alone, Nucor reported $7.83 billion in sales and employs around 25,000 people. It is also undertaking a major $3 billion expansion project in West Virginia, underscoring the scale and significance of its operations within the U.S. industrial sector. Cyberattacks on industrial firms are becoming more frequent. Recent 8-K filings related to cyber incidents have also come from companies like Masimo (medical technology), Sensata (industrial sensors), National Presto Industries (appliances), and Microchip Technology (semiconductors). 

Globally, firms in the U.K. and Switzerland have reported similar disruptions over the past year, highlighting a rising trend in targeted attacks on manufacturers. Given Nucor’s integral role in the U.S. supply chain, any disruption has broader implications. While no sensitive data leaks have been reported, the investigation is ongoing and law enforcement has been notified. 

Cybersecurity experts continue to urge industrial companies to invest in stronger digital defenses, especially as reliance on connected systems grows.

Scattered Spider Cyberattack Cripples M&S, Co-op: DragonForce Ransomware Causes Weeks-Long Disruption

 

Weeks after a significant cyberattack disrupted operations at major British retailers, companies like Marks & Spencer (M&S) and Co-op are still struggling to restore full functionality. Despite public reassurances, the scope of the attack is proving more serious than initially acknowledged. M&S CEO Stuart Machin recently confirmed that personal customer data had been accessed, prompting the company to require password resets for online accounts. Online orders on the M&S website remain suspended weeks after the breach, and no clear timeline has been offered for full recovery. 

The attack first became public on April 25 when M&S halted its online operations due to a cyber intrusion. Within days, Co-op revealed it had also been targeted in an attempted hack, which disrupted several services. Harrods, another luxury retailer, was also reportedly affected during this wave of cyberattacks. While M&S is still unable to process online sales, Co-op has only just resumed stocking its shelves, and both companies remain silent about when operations might return to normal. Government officials have weighed in on the seriousness of the incident. 

Cabinet Office Minister Pat McFadden called the attack a “wake-up call” for British businesses, highlighting the urgent need for enhanced cybersecurity protocols. Financial losses have been steep. M&S is reportedly losing £3.5 million per day while its website remains offline, and its stock has dropped by an estimated half a billion pounds in market value. Co-op also disclosed that customer data had been compromised, and they experienced issues with card payments at the height of the disruption. 

Investigations suggest the cybercriminal group known as Scattered Spider is responsible. Known for targeting large enterprises, the group is believed to have used a ransomware strain called DragonForce to paralyze systems. According to cybersecurity experts, the attackers may have exploited unpatched vulnerabilities and misconfigured systems to gain entry. Reports indicate they employed SIM-swapping tactics to hijack phone numbers and impersonate employees, fooling IT help desks into granting system access. Once inside, the hackers are believed to have compromised Microsoft Active Directory—a central hub that connects internal networks—potentially gaining access to crucial files and passwords. 

Though it’s unlikely they decrypted these password files directly, the level of access would have allowed them to severely disrupt internal systems. Experts say this level of infiltration can cripple multiple areas of a business, making recovery extremely challenging without a full rebuild of core IT infrastructure. One reason for the prolonged disruption may be that both M&S and Co-op chose not to pay the ransom, in line with UK government advice. While this decision aligns with best practices to avoid funding cybercrime, it also means recovery will take significantly longer. 

Despite the chaos, M&S has emphasized that no payment information or account passwords were compromised. The company is urging customers to reset their passwords for peace of mind and has provided guidelines on staying safe online. Co-op has resumed deliveries to most of its stores but acknowledged that some shelves may still lack regular stock. Empty shelves and apology signs have appeared across affected stores, as customers share their frustrations online. 

This incident underscores the growing threat posed by sophisticated cybercriminals and the urgent need for companies to prioritize cybersecurity. From exploiting human error to using advanced ransomware tools, the tactics are evolving, and so must the defenses.

Lostkeys Malware: Russian Group Coldriver Targets Western Officials in Espionage Campaign

 

A new wave of cyber espionage has emerged, with Russian hackers deploying a sophisticated malware strain known as “Lostkeys” to infiltrate the systems of Western officials, journalists, and NGOs. According to researchers from Google’s Threat Intelligence Group, the malware is linked to Coldriver, also known as UNC4057, Star Blizzard, or Callisto—a threat actor believed to be part of Russia’s Federal Security Service (FSB), the successor to the KGB. 

Coldriver has traditionally been involved in phishing operations to steal credentials, but the emergence of Lostkeys demonstrates a significant leap in their cyber capabilities. Lostkeys appears to mark a shift in strategy for the group, moving beyond phishing and into deeper system infiltration. The malware is deployed in a targeted manner, reserved for high-value individuals such as political advisors, think tank members, journalists, and people with known connections to Ukraine.

Activity related to Lostkeys was observed by Google in the early months of 2024—specifically January, March, and April—with evidence suggesting its use might have started as far back as December 2023. The attack begins with a deceptive Captcha page, tricking victims into copying a malicious PowerShell script into the Windows Run dialog. This method, known as “ClickFix,” bypasses typical security filters and exploits user behavior rather than software vulnerabilities. 

Once executed, the script connects to a command-and-control server, downloading a series of payloads uniquely tailored to each victim. In an effort to avoid detection, the malware includes anti-sandbox measures. During the second stage of infection, the script checks the screen resolution of the host machine and halts if it matches known virtual machine environments used by analysts and cybersecurity researchers. If the device passes this check, the malware proceeds to the final stage—a Visual Basic Script that steals data, including specific file types, system details, and active processes. These are exfiltrated back to the attackers using an encoded system that applies a unique two-key substitution cipher for each infected machine. 

Lostkeys appears to be a more refined successor to a previous malware strain known as Spica, which Coldriver also deployed in 2024. While both strains focus on data exfiltration, Lostkeys features a more intricate delivery system and improved obfuscation techniques. Some earlier samples of Lostkeys mimicked legitimate software like Maltego and used executable files instead of PowerShell, though Google has not confirmed if these instances were part of the same campaign or the work of a different threat actor reusing Coldriver’s tactics. 

This development highlights an alarming evolution in state-backed cyber operations, where advanced social engineering and stealth techniques are being increasingly used to infiltrate high-profile targets. As geopolitical tensions persist, the risks posed by such targeted cyber espionage campaigns are expected to grow.

iHeartMedia Cyberattack Exposes Sensitive Data Across Multiple Radio Stations

 

iHeartMedia, the largest audio media company in the United States, has confirmed a significant data breach following a cyberattack on several of its local radio stations. In official breach notifications sent to affected individuals and state attorney general offices in Maine, Massachusetts, and California, the company disclosed that cybercriminals accessed sensitive customer information between December 24 and December 27, 2024. Although iHeartMedia did not specify how many individuals were affected, the breach appears to have involved data stored on systems at a “small number” of stations. 

The exact number of compromised stations remains undisclosed. With a network of 870 radio stations and a reported monthly audience of 250 million listeners, the potential scope of this breach is concerning. According to the breach notification letters, the attackers “viewed and obtained” various types of personal information. The compromised data includes full names, passport numbers, other government-issued identification numbers, dates of birth, financial account information, payment card data, and even health and health insurance records. 

Such a comprehensive data set makes the victims vulnerable to a wide array of cybercrimes, from identity theft to financial fraud. The combination of personal identifiers and health or insurance details increases the likelihood of victims being targeted by tailored phishing campaigns. With access to passport numbers and financial records, cybercriminals can attempt identity theft or engage in unauthorized transactions and wire fraud. As of now, the stolen data has not surfaced on dark web marketplaces, but the risk remains high. 

No cybercrime group has claimed responsibility for the breach as of yet. However, the level of detail and sensitivity in the data accessed suggests the attackers had a specific objective and targeted the breach with precision. 

In response, iHeartMedia is offering one year of complimentary identity theft protection services to impacted individuals. The company has also established a dedicated hotline for those seeking assistance or more information. While these actions are intended to mitigate potential fallout, they may offer limited relief given the nature of the exposed information. 

This incident underscores the increasing frequency and severity of cyberattacks on media organizations and the urgent need for enhanced cybersecurity protocols. For iHeartMedia, transparency and timely support for affected customers will be key in managing the aftermath of this breach. 

As investigations continue, more details may emerge regarding the extent of the compromise and the identity of those behind the attack.

Millions of Co-op members are being urged to remain vigilant following a significant cyberattack that led to a temporary shutdown of the retailer’s IT infrastructure. The company confirmed that the breach resulted in unauthorized access to sensitive customer data, although it emphasized that no financial or account login information was compromised. 

Shirine Khoury-Haq, Chief Executive Officer of Co-op, addressed members directly, expressing regret and concern over the breach. She assured customers that the company’s core operations were largely unaffected by the attack and that members could continue to use their accounts and services as normal. However, she acknowledged the seriousness of the data exposure, which has affected both current and past members of the Co-op Group. 

“We deeply regret that personal member information was accessed during this incident. While we’ve been able to prevent disruption to our services, we understand how unsettling this news can be,” Khoury-Haq stated. “I encourage all members to take standard security precautions, including updating their passwords and ensuring they are not reused across platforms.” 

According to an official statement from Co-op, the malicious activity targeted one of their internal systems and successfully extracted customer data such as names, contact information, and dates of birth. Importantly, the company clarified that no passwords, payment details, or transactional records were included in the breach. They also emphasized that their teams are actively investigating the incident in coordination with the National Cyber Security Centre (NCSC) and the National Crime Agency (NCA). 

The company said that it has implemented enhanced security measures to prevent further unauthorized access, while minimizing disruption to business operations and customer services. Forensic specialists are currently assessing the full scope of the breach, and affected individuals may be contacted as more information becomes available.

Pakistan-Based Hackers Launch Cyber Attack on Indian Defence Websites, Claim Access to Sensitive Data

 

In a concerning escalation of cyber hostilities, a Pakistan-based threat group known as the Pakistan Cyber Force launched a coordinated cyber offensive on multiple Indian defence-related websites on Monday. The group claimed responsibility for defacing the official site of a Ministry of Defence public sector undertaking (PSU) and asserted that it had gained unauthorized access to sensitive information belonging to Indian defence personnel. According to reports, the targeted websites included those of the Military Engineering Service (MES) and the Manohar Parrikar Institute of Defence Studies and Analyses (MP-IDSA), both critical components in India’s defence research and infrastructure network. 

The group’s social media posts alleged that it had exfiltrated login credentials and personal data associated with defence personnel. One particularly alarming development was the defacement of the official website of Armoured Vehicle Nigam Limited (AVNL), a key PSU under the Ministry of Defence. The hackers replaced the homepage with the Pakistani flag and an image of the Al Khalid tank, a symbol of Pakistan’s military capabilities. A message reportedly posted on social platform X read, “Hacked. Your security is illusion. MES data owned,” followed by a list of names allegedly linked to Indian defence staff. 

Sources quoted by ANI indicated that there is a credible concern that personal data of military personnel may have been compromised during the breach. In response, authorities promptly took the AVNL website offline to prevent further exploitation and launched a full-scale forensic audit to assess the scope of the intrusion and restore digital integrity. Cybersecurity experts are currently monitoring for further signs of intrusion, especially in light of repeated cyber threats and defacement attempts linked to Pakistani-sponsored groups. 

The ongoing tensions between the two countries have only heightened the frequency and severity of such state-aligned cyber operations. This latest attack follows a pattern of provocative cyber incidents, with Pakistani hacker groups increasingly targeting sensitive Indian assets in attempts to undermine national security and sow discord. Intelligence sources are treating the incident as part of a broader information warfare campaign and have emphasized the need for heightened vigilance and improved cyber defense strategies. 

Authorities continue to investigate the breach while urging government departments and defense agencies to reinforce their cybersecurity posture amid rising digital threats in the region.

Pune-Based Biopharma Company Hit by Ransomware Attack, Hackers Demand $80,000

 

A multinational biopharmaceutical company based in Pune has fallen victim to a sophisticated ransomware attack, with cybercriminals encrypting vital data and demanding $80,000 (over Rs 68 lakh) for its release. The attackers have also threatened to leak the stolen proprietary data on the dark web if the ransom is not paid, according to local police authorities. 

The incident came to light when a senior executive from the company’s Pune office lodged a complaint at the Cyber Crime Police Station of Pimpri Chinchwad on Monday evening. The attack was first identified on Sunday afternoon, prompting immediate concern due to the sensitivity of the data involved. According to initial investigations by cybercrime officials, the breach is believed to have occurred through a compromised endpoint device—most likely via a phishing email containing a malicious link. 

Once the attackers gained access to the internal network, they deployed ransomware to the company’s main server and extended it to more than a dozen connected servers. Sensitive data, including proprietary pharmaceutical formulations, manufacturing protocols, and confidential business documents, was then encrypted and locked. 

“A preliminary probe suggests that vulnerabilities in the company’s cybersecurity setup allowed the attackers to infiltrate its systems,” an officer from the Cyber Police Station said. “Unfortunately, a significant portion of the critical data was not backed up offline, leaving the organization exposed to potential data loss if the ransom is not paid.” The hackers have made it clear that if their ransom demand of $80,000 is not met, the stolen data will be sold on the dark web. 

So far, the company has not paid the ransom, and authorities are currently analyzing IP logs and other digital evidence to trace the origin of the attack. Cybercrime investigators have urged all businesses to strengthen their cybersecurity measures, including regularly backing up data offline, updating firewall configurations, and educating employees about phishing threats. “This incident is a wake-up call for organizations to prioritize robust digital security,” the officer added.  

Deputy Commissioner of Police (Crime) Sandeep Doiphode emphasized the growing need for enterprises to invest in both technology and skilled cybersecurity personnel. “This case underlines the urgent necessity for companies to stay ahead of evolving threats through both infrastructure and human resource development,” he said. Police also noted that ransomware attacks typically use phishing emails and exploit weak security protocols. Payments are often demanded in cryptocurrency, making the attackers harder to trace. 

The investigation remains ongoing.

Malware Hides in Fake PDF to DOCX Converters to Target Crypto Wallets and Steal Data

 

Cybercriminals have launched a deceptive malware campaign that disguises itself as online file converters, specifically targeting users searching for PDF to DOCX tools. This scheme uses convincing replicas of popular converter sites to execute hidden PowerShell scripts and deploy a Remote Access Trojan designed to steal sensitive data, including cryptocurrency wallets and browser credentials. 

Security researchers at CloudSEK investigated the threat following an FBI warning issued last month. They discovered that attackers are using a malware variant called Arechclient2, derived from the known info-stealing family SectopRAT. The campaign works by luring unsuspecting users to malicious websites that impersonate legitimate services like PDFCandy. These fake platforms feature realistic user interfaces, including loading indicators and CAPTCHA forms, to establish trust before delivering the malware. When a user attempts to convert a file, they are redirected multiple times before receiving a ZIP archive named “adobe.zip.” Inside the archive is the malicious payload, which installs the Arechclient2 Remote Access Trojan. 

This malware, active since 2019, is capable of scanning for browser-saved credentials, cryptocurrency wallet seed phrases, and even tapping into decentralized finance tools via Web3 APIs. Stephen Ajayi, Technical Lead at Hacken’s Dapp Audit division, explained that the malware not only lifts crypto wallet details but also enables attackers to “ghost-drain” assets after a transaction approval—making it especially dangerous for Web3 users. CloudSEK advises users to avoid downloading tools from unofficial or unverified sites, particularly free online file converters. Instead, they recommend trusted offline software or tools from official sources. 

They also warn that malicious files often disguise themselves using harmless-looking extensions, so users should inspect file types carefully and use reliable antivirus or endpoint detection software. Ajayi emphasized the importance of a proactive security mindset. “In cybersecurity, trust should be earned. Assume nothing is safe by default,” he said. He advised crypto users and general web users alike to adopt a zero-trust approach, keep their security tools updated, and monitor systems for unusual activity such as rogue msbuild.exe processes. 

As threats like these evolve, staying vigilant, maintaining strong security protocols, and preparing for worst-case scenarios are critical steps for avoiding compromise. Regular training and a well-tested incident response plan remain key defenses against such deceptive but damaging attacks.

Cybercriminals Behind DOGE Big Balls Ransomware Demand $1 Trillion, Troll Elon Musk

 

A cybercrime group notorious for its outrageous tactics has resurfaced with a ransomware attack demanding an unbelievable $1 trillion from its victims. The group, responsible for the DOGE Big Balls ransomware campaign, has updated its ransom demands with bizarre references to Elon Musk and the Dogecoin meme culture, blending humor with a highly dangerous threat.  

According to a report by Trend Micro researchers Nathaniel Morales and Sarah Pearl Camiling, the attackers are leveraging a modified form of the FOG ransomware to carry out these intrusions. The malware exploits a long-known Windows vulnerability (CVE-2015-2291) through a multi-step PowerShell script that allows deep access into infected systems. Delivered via deceptive shortcut files inside ZIP folders, the malware initiates a chain reaction to execute its payload. Though the ransom note may appear comical—mocking Musk’s past corporate directives and making false claims about stealing “trilatitude and trilongitude” coordinates—the security community warns against taking this threat lightly. 

The ransomware performs environment checks to avoid detection, analyzing machine specs, RAM, and registry entries to detect if it’s being run in a sandbox. If any signs of monitoring are detected, the malware will exit silently. The FBI, in its April 2025 Internet Crime Report, highlighted ransomware—particularly FOG variants—as a dominant threat, impacting critical infrastructure and organizations across the U.S. The report revealed over 100 known FOG ransomware infections between January and March 2025, making it the most reported strain of the year thus far. Beyond encryption, the malware also exfiltrates sensitive data and pressures victims to communicate via the Tor network for instructions. 

The attackers claim stolen files and urge victims not to involve law enforcement, adding a “don’t snitch now” line in their taunting ransom message. Despite its absurd tone, security leaders emphasize the seriousness of the attack. Dr. Ilia Kolochenko, CEO of ImmuniWeb, cautions that many victims discreetly pay ransoms to groups known for not leaking data—urging companies to seek legal and cybersecurity advice before making decisions. 

Although the group hides behind memes and internet jokes, their ability to cause significant operational and financial disruption is very real. Their humor might distract, but the threat demands urgent attention.
