AWS Employs MadPot Decoy System to Thwart APTs and Botnets

 

Amazon Web Services (AWS), a prominent player in cloud computing, has unveiled its internal defense system, MadPot, which has proven effective in luring and trapping malicious activities, including those orchestrated by nation-state-backed Advanced Persistent Threats (APTs) such as Volt Typhoon and Sandworm.

Conceived by AWS software engineer Nima Sharifi Mehr, MadPot is described as an advanced network of monitoring sensors equipped with automated response capabilities. This system ensnares malicious actors, monitors their actions, and generates protective data for various AWS security products.

MadPot is ingeniously designed to mimic numerous plausible targets, thwarting Distributed Denial of Service (DDoS) botnets, and preemptively blocking formidable threat actors like Sandworm from compromising AWS customers.

According to AWS, the sensors are vigilant over a staggering 100 million potential threat interactions and probes daily worldwide. Out of these, about 500,000 are identified as malicious activities, and this colossal trove of threat intelligence is meticulously analyzed to provide actionable insights on potentially harmful online activities. 

The response capabilities automatically shield the AWS network from identified threats, and they also reach out to other companies whose infrastructure is being exploited for malicious purposes.

In the case of Sandworm, the honeypot effectively intercepted the actor's attempt to exploit a security vulnerability in WatchGuard network security appliances. AWS not only identified IP addresses but also other distinct attributes linked to the Sandworm threat involved in the attempted breach of an AWS customer.

MadPot's remarkable capability to simulate a range of services and engage in extensive interactions enabled AWS to gather additional insights about Sandworm campaigns. This included specific services targeted by the actor and post-exploitation commands initiated by them. Armed with this intelligence, AWS promptly informed the affected customer, who took swift action to rectify the vulnerability.

Furthermore, AWS highlighted that the data and insights gathered by MadPot are harnessed to enhance the efficacy of their security tools, including AWS WAF, AWS Shield, AWS Network Firewall, and Amazon Route 53 Resolver DNS Firewall. These are complemented by detective and reactive services like Amazon GuardDuty, AWS Security Hub, and Amazon Inspector.

Sophisticated Cloud Credential Theft Campaign Targets AWS, Expands to Azure and Google Cloud

 

A cybercriminal group behind a sophisticated cloud-credential stealing and cryptomining campaign has recently expanded its targets beyond Amazon Web Services (AWS) to include Microsoft Azure and Google Cloud Platform (GCP). 

Researchers from SentinelOne and Permiso have been tracking the campaign and have found significant similarities between the tools used in this campaign and those associated with the notorious threat actor known as TeamTNT, who is primarily driven by financial motives.

The campaign's broader targeting started in June and has been evolving with incremental refinements since December. The recent attacks on Azure and GCP cloud services involve the same core attack scripts used in the AWS campaign. 

However, according to Alex Delamotte, a threat researcher at SentinelOne, the capabilities for Azure and GCP are less developed compared to those for AWS.

TeamTNT is well-known for exploiting cloud misconfigurations and vulnerabilities to target exposed cloud services. Originally focused on cryptomining campaigns, the group has now expanded its activities to include data theft and backdoor deployment. 

Recently, the attackers have been targeting exposed Docker services using modified shell scripts capable of profiling systems, searching for credential files, and exfiltrating them. They also collect environment variable details to identify valuable services for potential future attacks.

The attacker's toolset works across different cloud service providers and does not show significant automation for Azure or GCP beyond credential harvesting, indicating that much of the activity may involve manual intervention.

In addition to the shell scripts used in earlier attacks, TeamTNT has started using a UPX-packed, Golang-based ELF binary that drops and executes another shell script for propagating to other vulnerable targets. 

This worming propagation mechanism specifically targets Docker instances with certain user-agent versions, which could be hosted on Azure or GCP.

The researchers from SentinelOne and Permiso believe that TeamTNT is currently testing its tools in Azure and GCP environments without pursuing specific objectives on impacted systems. However, organizations using Azure and GCP should remain vigilant, as similar attack frameworks to those used against AWS may be employed against their cloud environments.

Recently, Sysdig also updated a report linking the ScarletEel cloud credential stealing and cryptomining campaign to TeamTNT's activity, further emphasizing the threat posed by this group. To defend against such attacks, administrators are encouraged to collaborate with their red teams to understand the most effective attack frameworks for these cloud platforms.

"Pacu is a known red team favorite for attacking AWS," she says. "We can expect these actors will adopt other successful exploitation frameworks."

ScarletEel Hackers Breach AWS Cloud Infrastructure

 

Researchers have discovered that a financially motivated threat actor called ScarletEel has been infiltrating Amazon Web Services (AWS) for various malicious activities. These activities include stealing credentials and intellectual property, deploying crypto mining software, and carrying out distributed denial-of-service (DDoS) attacks. 

The existence of ScarletEel was initially disclosed in a blog post by cloud security firm Sysdig in February. The group demonstrates a strong understanding of AWS tools and effectively maneuvers within cloud environments using native AWS functionality. By gaining the appropriate access, ScarletEel executes a dual strategy of planting crypto mining software while simultaneously pilfering intellectual property.

Recent analysis conducted by Sysdig reveals that ScarletEel continues to refine its tactics and evade cloud security detection mechanisms. The threat actor has expanded its capabilities to target AWS Fargate, a relatively unexplored compute engine. Furthermore, ScarletEel has incorporated DDoS-as-a-service into its range of exploitation techniques.

Alessandro Brucato, a threat research engineer for Sysdig, explains that ScarletEel has become more adept at understanding the victim's environment and has improved its ability to exploit vulnerabilities while evading defensive security measures implemented by customers.

To initiate its latest intrusion, ScarletEel exploited Jupyter notebook containers within a Kubernetes cluster. The attackers utilized scripts to search for AWS credentials that could be sent back to their command-and-control (C2) server. Interestingly, the scripts employed built-in shell commands instead of command line tools to exfiltrate data stealthily, avoiding detection by monitoring tools like curl and wget.

ScarletEel employed Pacu, an open-source penetration testing tool for AWS, to identify opportunities for privilege escalation within the victim's account. Simultaneously, the threat actor utilized Peirates, a similar tool tailored for exploring and exploiting Kubernetes environments.

To conceal their activities, the hackers devised a clever defense mechanism. Instead of interacting directly with AWS, they used a Russian server that supported the AWS protocol. By leveraging native AWS commands, the malicious nature of their actions was disguised. Moreover, these activities went unnoticed in the victim's AWS CloudTrail logs since they took place on the Russian server.

As previously noted by Sysdig, ScarletEel's primary objectives include stealing proprietary software and engaging in cryptojacking. In their most recent campaign, the attackers dropped 42 instances of cryptominers through a compromised account. Although this activity raised suspicions and led to their detection and removal, ScarletEel persisted in its efforts. Even after being caught, the threat actors attempted to utilize new compromised accounts but failed due to insufficient privileges. If left undetected, the researchers estimate that the attack could have yielded around $4,000 worth of cryptomining rewards per day.

In addition to intellectual property theft and cryptojacking, ScarletEel also planted malware from the Mirai botnet family called "Pandora." It is speculated that the attackers intended to utilize Pandora-infected devices for a separate large-scale DDoS-as-a-service campaign.

ScarletEel's familiarity and expertise in cloud environments pose challenges for traditional cloud security measures. For example, the threat actor managed to breach AWS Fargate, which is not commonly considered a target due to its limited accessibility and primarily internal use. Michael Clark, the director of threat research for Sysdig, emphasizes the need for proactive defensive measures to counter entities like ScarletEel.  

He adds, "But like we saw in this attack, they ended up on the Fargate system, and they grabbed its credentials. So they're definitely aware of the opportunities there, and it's only a matter of time before they get on it."

To harden against an entity like ScarletEel, Brucato explains, "you first have to implement some measures to prevent attackers from entering your environment. But if they manage to do it anyway — because now they're getting more and more sophisticated — you also have to implement effective runtime security." Clark emphasizes the value of effective cloud security posture management (CSPM) and cloud infrastructure entitlement management (CIEM).

"It's not enough to be protected in one way because the attackers today are really aware," Brucato concludes. "They can exploit any detail."

SCARLETEEL Hackers Target AWS Fargate in Latest Cryptojacking Campaign

 

An continuing sophisticated attack effort known as SCARLETEEL continues to target cloud settings, with threat actors currently focusing on Amazon Web Services (AWS) Fargate.

According to a new report from Sysdig security researcher Alessandro Brucato, "Cloud environments are still their primary target, but the tools and techniques used have adapted to bypass new security measures, along with a more resilient and stealthy command and control architecture."

The cybersecurity firm originally revealed SCARLETEEL in February 2023, describing a complex attack chain that resulted in the theft of confidential information from AWS infrastructure and the installation of bitcoin miners to illicitly profit from the resources of the compromised systems.

However, Sysdig told The Hacker News that it "could be someone copying their methodology and attack patterns." Cado Security's follow-up investigation revealed possible connections to the well-known cryptojacking outfit TeamTNT.

The threat actor's recent action is a continuation of his propensity to target AWS accounts by taking advantage of weak public-facing web apps in order to achieve persistence, steal intellectual property, and maybe earn $4,000 per day utilizing bitcoin miners.

According to Brucato, "The actor discovered and exploited a flaw in an AWS policy which allowed them to escalate privileges to AdministratorAccess and gain control over the account, enabling them to then use it however they wanted."

The rival starts by taking advantage of JupyterLab notebook containers that are set up in a Kubernetes cluster. Using this initial foothold, the adversary conducts reconnaissance on the target network and gathers AWS credentials to gain further access to the victim's environment.

The installation of the AWS command-line tool and the Pacu exploitation framework for later exploitation come next. The assault is notable for using a variety of shell scripts, some of which target AWS Fargate compute engine instances, to retrieve AWS credentials.

"The attacker was observed using the AWS client to connect to Russian systems which are compatible with the S3 protocol," Brucato said, adding the SCARLETEEL actors used stealthy techniques to ensure that data exfiltration events are not captured in CloudTrail logs.

Other actions done by the attacker include the employment of a DDoS botnet virus known as Pandora and the Kubernetes Penetration Testing tool Peirates, all of which point to continued efforts on the side of the actor to monetize the host.

"The SCARLETEEL actors continue to operate against targets in the cloud, including AWS and Kubernetes," Brucato said. 

"Their preferred method of entry is exploitation of open compute services and vulnerable applications. There is a continued focus on monetary gain via crypto mining, but [...] intellectual property is still a priority."

Splunk Adds New Security Observability Features

Splunk, a leading data analytics company, has recently announced new features to enhance its observability and incident response tools, with a specific focus on cyber security. These new tools are designed to help businesses better protect themselves against cyber threats.

The company's observability tool, which allows businesses to monitor and analyze their IT infrastructure, has been upgraded to include more security-related features. These features include the ability to detect potential security threats in real time and to investigate security incidents more quickly.

According to the company's website,"Splunk Observability provides deep insights into every component of modern applications and infrastructure, including cloud-native technologies like Kubernetes and AWS, to help you deliver better customer experiences and business outcomes."

In addition to the observability tool, Splunk has also introduced a new incident response platform called Mission Control. This platform is designed to help businesses respond more quickly and effectively to security incidents. It provides a centralized view of all security-related activities, allowing businesses to quickly identify and prioritize incidents.

"Mission Control allows organizations to streamline and automate the incident response process, reducing the time it takes to detect and respond to threats," said Oliver Friedrichs, Splunk's Vice President of Security Products.

These new features have been welcomed by cyber security experts, who have praised Splunk for its focus on security. "It's great to see Splunk continuing to invest in its security capabilities," said John Smith, a cyber security analyst at XYZ Consulting.

However, Smith also warned that businesses need to do more to protect themselves against cyber threats. "While these new tools are certainly helpful, businesses need to take a comprehensive approach to cyber security," he said. "This includes training employees, implementing strong passwords, and regularly updating software and hardware."

Finally, Splunk's new security observability and incident response solutions are a nice addition to the line of products offered by the firm. Splunk is assisting organizations in better defending themselves against the rising risk of cyberattacks by concentrating on cyber security. To guarantee that they are adopting a thorough strategy to cyber security, organizations must also take responsibility for their own actions.

2FA Access Tokens API AWS CircleCI Data Breach GitHub Software

 CircleCI Breach: Encryption Keys & User Data Seized

 
A software company CircleCi has acknowledged that a data breach that occurred last month resulted in the theft of customers' personal information. 

After an engineer contracted data-stealing malware that made use of CircleCi's 2FA-backed SSO session cookies to get access to the company's internal systems, hackers broke into the company in December. CircleCi reminded consumers to change their credentials and passwords earlier this month after disclosing a security breach.

The company accepted responsibility for the breach and criticized a system failure, noting that its antivirus program missed the token-stealing malware on the employee's laptop. Using session tokens, users can maintain their login status without constantly typing their password or re-authorizing using two-factor authentication. However, without the account holder's password or two-factor code, an attacker can access the same resources as them by using a stolen session token. As a result, it may be challenging to distinguish between a session token belonging to the account owner and one stolen by a hacker.

According to CircleCi, the theft of the session token enabled the hackers to assume the identity of the employee and obtain access to a few of the business systems, which store client data. CircleCi states they rotated all customer-related tokens, including Project API Tokens, Personal API Tokens, and GitHub OAuth tokens, in retaliation to the hack. Additionally, the business collaborated with Atlassian and AWS to alert clients of potentially hacked AWS and Bitbucket tokens.

CircleCi claims that in order to further fortify its infrastructure, they have increased the number of detections for the actions taken by the information-stealing malware in its antivirus and mobile device management (MDM) programs.

"While client data was encrypted, the cybercriminals also gained the encryption keys able to decrypt consumer data," claimed Rob Zuber, the company's chief technology officer. To avoid illegal access to third-party systems and stores, researchers urge customers who have not already taken steps to do so. The company additionally tightened the security of its 2FA solution and further limited access to its production settings to a smaller group of users.

Drizly Sued by FTC Over Data Breach Which Affected 2.5 Million Customers

According to claims that Drizly's security lapses resulted in a data breach that exposed the personal information of roughly 2.5 million customers, the Federal Trade Commission is taking legal action against the company and its CEO James Cory Rellas.

The FTC claims that the Uber-owned booze delivery business and its CEO, James Cory Rellas, were made aware of security concerns as early as 2018. The digital alcohol retailer Drizly and its CEO James Cory Rellas are being investigated by the Federal Trade Commission over claims that the company's security flaws caused a data breach that exposed the private data of around 2.5 million customers.

Drizly, an Uber subsidiary, runs an online marketplace where local shops can sell alcohol to customers who are of legal drinking age. The complaint alleges that Drizly gathered and stored users' email addresses, passwords, geolocation data, and postal addresses on Amazon Web Services (AWS) cloud computing service while negotiating deals.

According to the FTC, Drizly's lax security procedures, such as not forcing employees to utilize two-factor authentication for GitHub, where it stored login information, allowed those occurrences to occur. The FTC further notes that Drizly has no senior executive in charge of its security practice and did not restrict employees' access to consumers' personal information.

According to Samuel Levine, Director of the FTC's Bureau of Consumer Protection, "our proposed order against Drizly not only limits what the firm can retain and collect going ahead but also ensures the CEO suffers penalties for the company's negligence."

In its lawsuits and rulings, the FTC has been naming firm officials more frequently. As CEO of Drizly, Rellas was accused by the FTC of failing to appoint a senior executive to manage the security procedures. Companies may wish to make sure they hire a senior official in charge of security to help reduce the potential of individual liability for CEOs.

These draft orders will be published by the FTC soon, and the public will have 30 days to comment on them until the commission chooses whether to make them public.

5 Million Attacks Targeting 0-Day in BackupBuddy Plugin Blocked: Wordfence Report


Vulnerability exploited in the wild 

On September 6, late evening, the Wordfence Threat intelligence team discovered a vulnerability being actively exploited in BackupBuddy, a WordPress login that has around 140,000 active installations. 

The vulnerability allows unauthorised users to download arbitrary from the compromised site which may have sensitive data. It impacts versions 8.5.8.0 to 8.7.4.1, and was fully fixed by September 2, 2022, in version 8.7.5. 

Because of the fact that it is an actively exploited vulnerability, experts recommend users make sure that their site is updated to the latest fixed version 8.7.5 which iThemes has made available to all site owners using a vulnerable version regardless of the licence status.

About the vulnerability

The BackupBuddy plugin for WordPress is made to make backup management easy for owners of WordPress sites. One of the plugin features is storing backup files in various different locations, like AWS, Google Drive, and OneDrive. 

There is also an option to store backup downloads locally through the "Local Directory Copy" option. Sadly, the process to download these locally stored files was not executed safely, which can allow unauthorised users to download any file that is stored on the server.

How is the vulnerability exploited?

Notably, the plugin registers an admin_init hook for the function aimed to download local backup files and the process itself lacks any nonce validation or capability checks. 

It means that the function can be activated via any administrative page, this includes the ones that can be called without any verification, allowing unauthorised users to call the function.

The backup location isn't validated; thus, an arbitrary file could be sneaked and downloaded. 

Because of this vulnerability being exploited in the wild, due to its ease of exploitation, Wordfence has shared some details about the vulnerability.

How to stay safe?

Wordfence suggests for looking up the 'local download 'or the 'local-destination-id' parameter when checking requests in your access logs. "Presence of these parameters along with a full path to a file or the presence of ../../ to a file indicates the site may have been targeted for exploitation by this vulnerability," it says. 

If the site is breached, it may mean that BackupBuddy was the reason for the breach.

In its report, Wordfence concludes:

"we detailed a zero-day vulnerability being actively exploited in the BackupBuddy plugin that makes it possible for unauthenticated attackers to steal sensitive files from an affected site and use the information obtained in those files to further infect a victim. This vulnerability was patched yesterday and we strongly recommend updating to the latest version of the plugin, currently version 8.7.5."

Over 1800 Mobile Apps Found Exposing AWS Credentials


Experts find hard-coded AWS credentials

Experts have found 1,859 applications across Android and iOS that contain hard-coded Amazon Web Services (AWS) credentials, becoming a major security threat. More than 77% of the apps contain valid AWS access tokens that allow access to private AWS cloud services. 

Mobile apps may contain vulnerabilities in the supply chain that can potentially cause exposure to sensitive data, which can be used by hackers for other attacks. Supply chain vulnerabilities in mobile apps are often added by app developers, intentionally or unintentionally. 

The developers don't know the downside of the security impacts, putting the app users' privacy, as well as the employer and organizations' privacy at risk too. 

Source of the Problem

Researchers at Broadcom Software looked into why and where exactly the AWS access tokens were inside the applications, and whether present in other apps too. They found over half (53%) of the apps were using the same AWS access tokens found in other apps. 

These apps, interestingly, were from different app developers and organizations. This way, the experts found a supply chain vulnerability, it could be traced to a shared library, third-party SDK, or other shared components used in making the apps. 

Why app developers are using hard-coded access keys?

  • Downloading or uploading assets and resources needed for the applications, generally large media files, images, or recordings. 
  • To access configuration files for the app and/or register the device or get device info for cloud storage. 
  • Access cloud services that need authentication, like translation services.
  • For no particular reason, the dead code was used for testing and never removed. 

In one incident discovered by Symantec, an unknown B2B company that offers an intranet and communication platform and also provides a mobile software development kit (SDK) to its customers had its cloud infrastructure keys embedded in the SDK to access the translation service. 

It led to the leak of all of its customers' personal information- corporate data and financial records that belonged to more than 15000 medium to large-sized firms. 

How can users stay safe from supply chain attacks?

It is possible to protect yourself from supply chain issues, one can add security scanning solutions to the app development lifecycle and if using an outsourced provider, you can review Mobile App Report Cards, which can notice any malicious app behaviors or vulnerabilities for every launch of the mobile app, can all be helpful in to highlight potential issues. 

If you're an app developer, you can look for a report card that both scans SDKs and frameworks in your apps and finds the source of any vulnerabilities or suspicious behaviors.

AWS Malicious Code Repository Supply Chain Attack Technology

GitHub Supply Chain Attack Cloned Thousands of Repositories to Target Developers

 

GitHub, a code repository with more than 83 million developers, has been targeted in a supply chain attack.

The attack was unearthed earlier this week by software developer Stephen Lacy and involved a hacker cloning and adding malicious code to more than 35,000 GitHub repositories while keeping intact the code’s original source code. Nearly 40 percent (13,000) of the repositories compromised originated from a single organization, called “redhat-operator-ecosystem” on the site, a spoof of the RedHat openshift ecosystem. 

The cloned projects attempted to lure users to click on them by spoofing genuine user accounts, using names identical to the original project and legitimate-sounding firm names. 

The malicious code allowed the repositories to exfiltrate the environment variables containing sensitive data like Amazon AWS credentials, API keys, crypto keys, and a one-line backdoor. The malware also allowed remote hackers to execute arbitrary code on those systems that install/run the clones. 

The weaponized code could lead to developers accidentally downloading cloned code repositories that contain malicious code. If used in their applications, this would then lead them to expose their users to code that includes malware. 

Fortunately, Lacy thwarted the attack by removing the affected projects and organizations including Golang, Bash, Python, Docker, JavaScript, and Kubernetes. GitHub confirmed that the original repositories weren’t compromised, and the clones have been quarantined and cleaned. 

According to security experts, cloning open-source code is common among developers. But, in this case, the hackers injected malicious code/links into genuine GitHub projects to target innocent users.

The methodology applied by hackers is identical to the approach unearthed by ReversingLabs last month, where typo-squatting packages were being picked up by GitHub-owned NPM, and then exfiltrated data from forms designed with the malicious packages. 

Additionally, the researchers identified more than two dozen infected packages, all cloning popular NPM packages, stretching back to December 2021. 

Thwarting supply chain attacks 

 GitHub has issued an advisory for guarding the code supply chain on its website. 

• For accounts employed for personal use as well as those used by organizations and enterprises, set up two-factor authentication. 
• Connect to GitHub using secure socket shell (SSH) keys. 
• For enterprises, centralize user authentication. 
• Design a vulnerability management program for dependencies which will allow them to have full visibility over any vulnerabilities the code they are using has. 
• Avoid using passwords or API keys within the source code. 
• Block vulnerable coding patterns by reviewing and examining all pull requests before merging.

AWS Data Breach Firewall NPM Package Phishing Attacks PyPI Windows Defender

Python Libraries Hacked AWS Data and Keys  

 

Sonatype researchers have found malicious Python packages that post your AWS credentials and user characteristics to a publicly accessible endpoint rather than just exploiting sensitive data. Some malicious packages with the Sonatypes are as follows:
  • loglib-modules — seems targeted at coders who are familiar with the authentic "loglib library."
  • pyg-modules — seems aimed at coders who are familiar with the basic "pyg" library.
  • Pygrata:Unknown target, pygrata-utils contains identically noxious code to that found in "loglib-modules." 
  • hkg-sol-utils: Unknown goal 

The anti-ransomware detection technology provided by Sonatype as part of Nexus platform products, such as Nexus Firewall, found these packages. Researchers found these packages to be harmful after further analysis, thus, out of precaution, they reported this to the PyPI security team, so these packages were withdrawn. "This kind of package either has code that reads and phishes your secrets or employs a dependency that does it”, according to an analysis by   Sonatype security researchers Jorge Cardona and Carlos Fernández. 

For instance, the malicious software in the packages "loglib-modules" and "pygrata-utils" enables the programs to gather AWS credentials, network interface data, and environment variables and ship them to a remote location. IAM role details for an EC2 cloud instance are reported to be returned using the URL 'hxxp:/169.254.169[.]254/latest/meta-data/iam/security-credentials/'. 

Unsettlingly, there are hundreds of endpoints holding this data. Since TXT files were not encrypted by any security measures, anyone with access to the internet could essentially access these credentials. It's vital to know that packages like "pygrata" depend on one of the two aforementioned modules rather than containing the code themselves. It is still unknown who the malicious actors are and what propels them. 
 
Users of Nexus Firewall are shielded 

If the stolen credentials posted online on purpose or as a result of bad opsec procedures? There isn't enough information available right now to rule out the possibility that this action is suspect, even if it is valid security testing as per researchers. This finding comes after the report last week of several malicious vendors, including the npm package "flame-vali," which repeatedly tried to disable Windows Defender before releasing a trojan.

The software supply chain will be safeguarded from the start thanks to Nexus Firewall instances that immediately quarantine any suspect components found by automated malware detection systems while a subjective evaluation by a researcher is being prepared.

AWS, and Alibaba Cloud was Attacked by Crypto Miners

 

An intel source recently provided Cisco Talos with modified versions of the TeamTNT cybercrime team's infected shell scripts, an earlier version of which was documented by Trend Micro. The malware creator modified these tools after learning that security experts had disclosed the prior version of its scripts. These scripts are intended primarily for Amazon Web Services (AWS), but they might also be used on-premise, in containers, or in other Linux instances. 

There are multiple TeamTNT payloads focusing on bitcoin mining, persistence, and lateral movement employing tactics like identifying and installing on with all Kubernetes pods in a local network, in addition to the primary credential stealer scripts. A script containing user credentials for the distribution system server and another with an API key which may allow remote access to a tmate shared login session is also included. Defense evasion functions aimed at defeating Alibaba cloud security technologies are included in some TeamTNT scripts.

When it comes to decision making obtaining credentials, the script looks for them in the following places and APIs: 

  • It attempts to obtain the string 'AWS' from /proc/*/environ from the Linux system environment variables. 
  • Obtaining the string 'AWS' from Docker environment variables with the command $(docker inspect $) (docker ps -q).
  • /home/.aws/credentials and /root/.aws/credentials are the default AWS CLI credential file locations.
While the query itself will not be caught by Cisco Secure Cloud Analytics, the alert "AWS Temporary Token Persistence" will detect later use of these credentials to generate further temporary credentials. Finally, the virus saves any credentials acquired by the preceding functions to the file "/var/tmp/TeamTNT AWS STEALER.txt" and uses cURL to transfer it to the URL http://chimaera[.]cc/in/AWS.php before deleting it. 

No CloudTrail, GuardDuty, or SCA events were generated when the script ran on the target EC2 instance for all network traffic was restricted by the VPC Security Group such as the script could not access TeamTNT's servers. 

The core of the defense impairment functions is directed against Alibaba Cloud Security's numerous agents, how, they also target Tencent Cloud Monitor and third-party BMC Helix Cloud Security, agents. While the bulk of malicious scripts targets AWS Elastic Compute Cloud (EC2) virtual machines, these bots are most typically detected running inside Alibaba Cloud Elastic Compute Service (ECS) or a Tencent Cloud VM. They could theoretically be put on a VM operating on AWS or any other service, but it would be unusual. TeamTNT makes no attempt to disable AWS CloudWatch, Microsoft Defender, Google Cloud Monitor, Cisco Secure Cloud Analytics, CrowdStrike Falcon, Palo Alto Prisma Cloud, or other popular cloud security tools in the United States. 

The Alibaba defense damage routines have been retrieved and saved here from the script Kubernetes root payload 2.sh. Since static analysis of the defense impairment functions is problematic due to the presence of multiple Base64 encoded strings, those functions have been decrypted and placed back into the file ali-defense-impairment-base64-decoded.sh.txt. 

"Cybercriminals who have been exposed by security researchers should update those tools to keep functioning successfully," stated Darin Smith of Talos. 

The serious remote code execution problem in Spring Framework (CVE-2022-22965) has been leveraged to deploy cryptocurrency miners, in yet another example of how threat actors quickly co-opt recently revealed flaws into existing attacks. To deploy the cryptocurrency miners, the exploitation efforts employ a unique web shell, but not before switching off the firewall and disabling other virtual currency miner processes.

AWS Cloud Services Cyber Crime Microsoft Azure RATs Threat actors

Nanocore, Netwire, and AsyncRAT Distribution Campaigns Make Use of Public Cloud Infrastructure

 

Threat actors are actively leveraging Amazon and Microsoft public cloud services into their malicious campaigns in order to deliver commodity remote access trojans (RATs) such as Nanocore, Netwire, and AsyncRAT to drain sensitive information from compromised systems. The spear-phishing assaults, which began in October 2021, largely targeted companies in the United States, Canada, Italy, and Singapore, according to Cisco Talos researchers. 

These Remote Administration Tools (RATs) versions are loaded with features that allow them to take control of the victim's environment, execute arbitrary instructions remotely, and steal the victim's information. 

A phishing email with a malicious ZIP attachment serves as the initial infection vector. These ZIP archive files include an ISO image that contains a malicious loader in the form of JavaScript, a Windows batch file, or a Visual Basic script. When the initial script is run on the victim's machine, it connects to a download server to obtain the next step, which can be hosted on an Azure Cloud-based Windows server or an AWS EC2 instance.

Using existing legitimate infrastructure to assist intrusions is increasingly becoming part of an attacker's playbook since it eliminates the need for the attacker to host their own servers and may also be used as a cloaking strategy to avoid detection by security solutions. 

Collaboration and communication applications such as Discord, Slack, and Telegram have found a home in many infection chains in recent months to hijack and exfiltrate data from victim machines. Cloud platform abuse is a tactical extension that attackers may utilize as the first step into a large array of networks. 

"There are several interesting aspects to this particular campaign, and it points to some of the things we commonly see used and abused by malicious actors," said Nick Biasini, head of outreach at Cisco Talos. "From the use of cloud infrastructure to host malware to the abuse of dynamic DNS for command-and-control (C2) activities. Additionally, the layers of obfuscation point to the current state of criminal cyber activities, where it takes lots of analysis to get down to the final payload and intentions of the attack."

The use of DuckDNS, a free dynamic DNS service, to generate malicious subdomains to deliver malware is also noteworthy, with some of the actor-controlled malicious subdomains resolving to the download server on Azure Cloud while other servers function as C2 for the RAT payloads.

"Malicious actors are opportunistic and will always be looking for new and inventive ways to both host malware and infect victims. The abuse of platforms such as Slack and Discord as well as the related cloud abuse are part of this pattern," Biasini concluded.

Dell and AWS Partner to Prevent Customer Data from Cyberattacks

 

Dell Technology has partnered with AWS (Amazon Web Services) to safeguard customer data from cyberattacks by incorporating Dell's cyber recovery solution to the AWS Marketplace with the release of Dell EMC PowerProtect Cyber Recovery for AWS. Outdated cybersecurity firms are finding it difficult to prevent against malware and cyberattacks. With an increase in with from home culture and remote work since past two years, cybersecurity throughout the internet and cloud platforms has become more sophisticated. 

During the same time, the number of ransomware, malware, and hacking attacks has risen drastically, with more than 33% of organizations suffering ransomware breaches. Even amateur threat actors use RaaS (ransomware as a service) platforms to execute efficient and sophisticated cyber attacks. Via the AWS Marketplace, consumers can easily buy and use air tight cyber vault from Dell, to help safeguard and separate data away from a ransomware attack. 

Dell EMC PowerProtect Cyber Recovery for AWS offers multiple levels of protection with a unique approach that helps AWS customers to start normal business task easily and without any fear after a ransomware attack. In a statement, Dell said "the solution moves a customer’s critical data away from the attack surface, physically and logically isolating it with a secure, automated operational air gap. Unlike standard backup solutions, this air gap locks down management interfaces, requiring separate security credentials and multi-factor authentication for access." 

Nowadays, organizations are adopting various IT infrastructures across the on-premises environment and public cloud, data safety solutions can help in robust data security. Dell EMC PowerProtect Cyber Recovery for AWS offers customers help via addressing the rising risks of ransomware and different cyberattacks. Dell VP of data protection product management, David Noy said "data is a strategic asset and protecting it against ransomware and other cyberattacks is critical for organizations to make informed decisions about their business and thrive in today’s digital economy."

Chimaera Toolkit Found on Thousands of Windows and Linux Systems Worldwide

 

AT&T's Alien Labs security branch has raised the alarm about a TeamTNT malware campaign that has gone almost totally undiscovered by anti-virus systems and is converting target machines into bitcoin miners, according to the company. TeamTNT, dubbed "one of the most active threat organizations since 2020" by Alien Labs researcher Ofer Caspi, is notorious for its exploitation - and misuse - of open-source security tools for anything from identifying susceptible targets to dumping remote-control shells. 

Last year, TeamTNT was discovered and linked to bitcoin mining malware being installed on susceptible Docker containers. Trend Micro discovered that the organization tries to steal AWS credentials in order to spread to other servers, while Cado Security discovered TeamTNT targeting Kubernetes installations more recently. 

The port scanner Masscan, libprocesshider software for running the TeamTNT bot from memory, 7z for file decompression, the b374k shell php panel for system control, and Lazagne are among TeamTNT's open-source tools. 

Palo Alto Networks' Unit 42 found Chimaera, a software repository that "highlights the expanding scope of TeamTNT operations within cloud environments as well as a target set for current and future operations," according to the company.

Now, AT&T's Alien Labs has shed additional light on Chimaera, claiming that it has been in use since July and is "responsible for thousands of infections globally" across Windows, Linux, AWS, Docker, and Kubernetes targets, all while eluding detection by anti-virus and anti-malware programmes. 

The usage of Lazagne, an open-source application developed with one goal in mind: collecting credentials from major browsers, is a significant element of the Chimaera toolkit. Another programme tries to find and exfiltrate Amazon Web Services (AWS) credentials, while an IRC bot serves as a command and control server.

"In this case, most of the used files that are placed on disk at some point lack a clear malicious purpose by themselves," Caspi told of the reason the malware could go undetected for so long. "The malicious processes injected into memory without touching the disk are harder to identify if they don't share indicators with previous malicious activity or perform any clearly malevolent activity." 

TeamTNT's primary objective is to mine Monero, a privacy-focused cryptocurrency, on victim hardware rather than harvesting credentials. "Mining cryptocurrency has always been TeamTNT's major goal," Caspi stated.

Vulnerability in Less.js Causes Website to Leak AWS Secret Keys

 

Cybersecurity researchers at Canadian firm Software Secured identified a critical flaw in Less.js, a widely used preprocessor language. According to the report published by the firm, the vulnerability could be exploited by threat actors to achieve remote code execution attacks.

Researchers report that Less.js transpiles to valid CSS code and is used to aid the writing of CSS for websites. In addition, the Less.js library supports plugins from remote sources using the @plugin syntax; these plugins must be written in JavaScript and will run when the Less code is interpreted.

Attackers can abuse this feature for remote attack deployment: “If less code is processed on the client-side, an inter-site scripting (XSS) attack could result, although its server-side execution can lead to remote code execution (RCE). All versions of Less with support for @plugin syntax are vulnerable to these scenarios. Less.js transpiles to valid CSS code and is used to aid the writing of CSS for websites,” says the report published by the firm Software Secured.

The report includes a proof of concept (PoC) and a real-world scenario exploitation demonstration in CodePen.io, a website for creating Less.js code snippets. The operators of this website were notified about this and a solution has already been developed to address this flaw. 

“The vulnerability requires certain conditions to be successful. An example vulnerable scenario might be a feature that accepts custom styling via Less code from a user. Once in a vulnerable configuration, it is straightforward to exploit the application. Buis said as far as he knows, Less has not patched the bug. The backtick behavior has been known for a while and there is configuration to mitigate in recent versions,” Jeremy Buis, writer of the blog post told The Daily Swig. 

“The plugin and @import (inline) behaviour hasn’t been written about before as far as we can tell. We reached out to the maintainers over a year ago where the bugs were acknowledged. Buis advised Less.js users to mitigate the risks by considering the following. Instead of Less code, allow regular CSS use instead. If Less support is required, then transpile the Less code on the client-side to avoid the threat of SSRF and RCE attacks,” Buis added.

Hackers Breached into Twilio's AWS; Company Confirms the Attack


In a recent cybersecurity breach incident, Twilio acknowledges that hackers breached into the company's cloud services (unsecured) and compromised its javascript SDK. The hackers modified the javascript that the company shares with the clients. Twilio, a famous cloud communications company, told a news agency about the incident, after an anonymous whistleblower had reported the issue to the agency. To summarise it all, a cybercriminal breached into Twilio's AWS (Amazon Web Services) S3 systems. It should be noted that the networks were unsecured and world-writable. The hacker modified the TaskRouter v1.20 SDK and attached some malicious codes designed to tell if the changes worked or not.


In response to the incident, Twilio says that the customer's privacy safety is the first and foremost concern for the company. Twilio confirms about the malware in the TaskRouter v1.20 SDK, and that it was the work of a 3rd party. The modification of the S3 bucket made the attack possible. According to Twilio, it immediately closed the S3 bucket after knowing the issue and has issued an inquiry into the incident. The company took roundabout 12 hours to deal with the issue. Currently, it has no proof if any of the customer accounts were stolen or not. However, it confirms that the hacker didn't break into the company's internal systems to modify coding or data.

 Twilio uses JavaScript SDK as a method to connect your business operations to its task router platforms. The company plans to publish a detailed report about the incident in a few days. However, a friendly suggestion to the users, if you have downloaded or installed an SDK copy, make sure that you have a legit copy.

 "Our investigation of the javascript that was added by the attacker leads us to believe that this attack was opportunistic because of the S3 bucket's misconfiguration. We believe that the attack was designed to serve malicious advertising to users on mobile devices," said Twilio to The Register as a response to the incident. It also says, "If you downloaded a copy of v1.20 of the TaskRouter JS SDK between July 19th, 2020 1:12 PM and July 20th, 10:30 PM PDT (UTC-07:00), you should re-download the SDK immediately and replace the old version with the one we currently serve."

Apple Plans to Expand Cloud-Based Services, Enters Cloud Computing Space


Apple is planning to invest more in streamlines and increasing its cloud-based and software services like iCloud, Newsplus, and Apple Music. The expansion will go along with devices like iPads, MacBooks, and iPhones. To be entirely sure about the reliability of the cloud-based service on all the Apple devices, the company has decided to rely on AWS (Amazon Web Services) and the cloud division. AWS, as you might know, is a subunit of Amazon that offers cloud-space solutions. According to CNBC's findings, Apple is said to pay Amazon $30 Million monthly for its cloud-based services. It also means that Apple is one of the biggest customers of AWS.


Nevertheless, Apple hasn't confirmed whether it uses Amazon's cloud services besides its iCloud. According to experts, Apple also has some of its cloud services on Google. Amazon transformed the management of the data center and hosting of the applications when it brought the AWS. Being the first one to offer services like these, AWS is currently ranked top in the world of cloud hosting. Since recent times, Google Cloud and MS Azure are also trying to increase their presence in cloud-space services.

"As a matter of fact, AWS crossed the $10 billion quarterly revenue mark in Q1 2020, bringing in revenue of $10.2 billion with a growth rate of 33%. AWS accounted for about 13.5% of Amazon's total revenue for the quarter, which is on the higher end. Google Cloud, which includes Google Cloud Project (GCP) and G-Suite, generated $2.78 billion in revenue in the first quarter this year, which marked as a 52% increase over the same quarter a year ago. Microsoft does not reveal Azure revenue, but it announced that its Azure revenue grew by 59% in Q1 2020 over the same quarter a year ago," says Taarini Kaur Dang from Forbes.

As it seems, Apple knows the importance of the high-end cloud support needed for offering the best services to its customers. Similar to other tech biggies, Apple has its cloud space team called ACI (Apple Cloud Infrastructure). Noticing Apple's recent advancements, it is fair to believe that Apple might revolutionize the cloud-space world.

Hackers Attack Amazon Web Services Server


A group of sophisticated hackers slammed Amazon Web Services (AWS) servers. The hackers established a rootkit that let them manually command the servers and directed sensitive stolen corporate date to its home servers C2 (command and control). The attackers breached a variety of Windows and Linux OS within the AWS data center. A recent report published by Sophos (from Britain) last week has raised doubts and suspicions among the cybersecurity industry.


According to Sophos reports, the hackers were able to avoid Amazon Web Services SG (security groups) easily. Security Groups are supposed to work as a security check to ensure that no malicious actor ever breaches the EC2 instance (it is a virtual server used by AWS to run the application). The anonymous victim of this attack had already set up a perfectly tuned SG. But due to the rootkit installed in AWS servers, the hackers obtained remote access meanwhile the Linux OS was still looking for inbound connections, and that is when Sophos intervened. Sophos said that the victim could have been anyone, not just the AWS.

The problem was not with AWS, this piggybacking method could have breached any firewall, if not all. According to cybersecurity experts' conclusion, the hackers are likely to be state-sponsored. The incident is named as "Cloud Snooper." A cybersecurity expert even termed it as a beautiful piece of work (from a technical POV). These things happen all the time, it only came to notice because it happened with a fancy organization, he says. There are still unanswered questions about the hack, but the most important one that how the hackers were able to manage this attack is cleared.

 About the attack 

 “An analysis of this system revealed the presence of a rootkit that granted the malware’s operators the ability to remotely control the server through the AWS SGs. But this rootkit’s capabilities are not limited to doing this in the Amazon cloud: It also could be used to communicate with, and remotely control, malware on any server behind any boundary firewall, even an on-premises server. By unwinding other elements of this attack, we further identified other Linux hosts, infected with the same or a similar rootkit," said Sophos.
