Red Hat on Friday released an "urgent security alert" warning that two versions of a popular data compression library called  XZ Utils  (previously LZMA Utils) have been backdoored with malicious code designed to allow unauthorized remote access. The software supply chain compromise, tracked as  CVE-2024-3094 , has a CVSS score of 10.0, indicating maximum severity. It impacts XZ Utils versions 5.6.0 (released February 24) and 5.6.1 (released March 9). "Through a series of complex obfuscations, the liblzma build process extracts a prebuilt object file from a disguised test file existing in the source code, which is then used to modify specific functions in the liblzma code," the IBM subsidiary  said  in an advisory. "This results in a modified liblzma library that can be used by any software linked against this library, intercepting and modifying the data interaction with this library." Specifically, the nefarious code baked into the code is  designed

Unidentified adversaries orchestrated a sophisticated attack campaign that has impacted several individual developers as well as the GitHub organization account associated with Top.gg, a Discord bot discovery site. "The threat actors used multiple TTPs in this attack, including account takeover via stolen browser cookies, contributing malicious code with verified commits, setting up a custom Python mirror, and publishing malicious packages to the PyPI registry," Checkmarx  said  in a technical report shared with The Hacker News. The software supply chain attack is said to have led to the theft of sensitive information, including passwords, credentials, and other valuable data. Some aspects of the campaign were  previously   disclosed  at the start of the month by an Egypt-based developer named Mohammed Dief. It chiefly entailed setting up a clever typosquat of the official PyPI domain known as "files. python hosted[.]org," giving it the name "files. pypi ho

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,

GitHub on Wednesday announced that it's making available a feature called code scanning autofix in public beta for all  Advanced Security customers  to provide targeted recommendations in an effort to avoid introducing new security issues. "Powered by  GitHub Copilot  and  CodeQL , code scanning autofix covers more than 90% of alert types in JavaScript, Typescript, Java, and Python, and delivers code suggestions shown to remediate more than two-thirds of found vulnerabilities with little or no editing," GitHub's Pierre Tempel and Eric Tooley  said . The capability,  first previewed  in November 2023, leverages a combination of CodeQL, Copilot APIs, and OpenAI GPT-4 to generate code suggestions. The Microsoft-owned subsidiary also said it plans to add support for more programming languages, including C# and Go, in the future. Code scanning autofix is designed to help developers resolve vulnerabilities as they code by generating potential fixes as well as providing

Cybersecurity researchers have found a number of GitHub repositories offering cracked software that are used to deliver an information stealer called RisePro. The campaign, codenamed  gitgub , includes 17 repositories associated with 11 different accounts, according to G DATA. The repositories in question have since been taken down by the Microsoft-owned subsidiary. "The repositories look similar, featuring a README.md file with the promise of free cracked software," the German cybersecurity company  said . "Green and red circles are commonly used on Github to display the status of automatic builds. Gitgub threat actors added four green Unicode circles to their README.md that pretend to display a status alongside a current date and provide a sense of legitimacy and recency." The list of repositories is as follows, with each of them pointing to a download link ("digitalxnetwork[.]com") containing a RAR archive file - andreastanaj/AVAST andreastanaj

Threat hunters have discovered a set of seven packages on the Python Package Index (PyPI) repository that are designed to steal  BIP39 mnemonic phrases  used for recovering private keys of a cryptocurrency wallet. The software supply chain attack campaign has been codenamed BIPClip by ReversingLabs. The packages were collectively downloaded 7,451 times prior to them being removed from PyPI. The list of packages is as follows - jsBIP39-decrypt  (126 downloads) bip39-mnemonic-decrypt  (689 downloads) mnemonic_to_address  (771 downloads) erc20-scanner  (343 downloads) public-address-generator  (1,005 downloads) hashdecrypt  (4,292 downloads) hashdecrypts  (225 downloads) BIPClip, which is aimed at developers working on projects related to generating and securing cryptocurrency wallets, is said to be active since at least December 4, 2022, when hashdecrypt was first published to the registry. "This is just the latest software supply chain campaign to target crypto assets," sec

Facebook messages are being used by threat actors to distribute a Python-based information stealer dubbed Snake that's designed to capture credentials and other sensitive data. "The credentials harvested from unsuspecting users are transmitted to different platforms such as Discord, GitHub, and Telegram," Cybereason researcher Kotaro Ogino  said  in a technical report. Details about the campaign  first emerged  on the social media platform X in August 2023. The attacks entail sending prospective users seemingly innocuous RAR or ZIP archive files that, upon opening, activate the infection sequence. The intermediate stages involve two downloaders – a batch script and a cmd script – with the latter responsible for downloading and executing the information stealer from an actor-controlled GitLab repository. Cybereason said it detected three different variants of the stealer, the third one being an executable assembled by PyInstaller. The malware, for its part, is designed to gather d

GitHub on Thursday announced that it's enabling secret scanning push protection by default for all pushes to public repositories. "This means that when a supported secret is detected in any push to a public repository, you will have the option to remove the secret from your commits or, if you deem the secret safe, bypass the block," Eric Tooley and Courtney Claessens  said . Push protection  was  first piloted  as an opt-in feature in August 2023, although it has been under testing since April 2022. It became  generally available  in May 2023. The  secret scanning  feature is designed to identify over  200 token types  and patterns from more than 180 service providers in order to prevent their fraudulent use by malicious actors.  The development comes nearly five months after the Microsoft subsidiary  expanded  secret scanning to include validity checks for popular services such as Amazon Web Services (AWS), Microsoft, Google, and Slack. It also follows the discovery of an ongoi

An "intricately designed" remote access trojan (RAT) called  Xeno RAT  has been made available on GitHub, making it easily accessible to other actors at no extra cost. Written in C# and compatible with Windows 10 and Windows 11 operating systems, the open-source RAT comes with a "comprehensive set of features for remote system management," according to its developer, who goes by the name moom825. It includes a SOCKS5 reverse proxy and the ability to record real-time audio, as well as incorporate a hidden virtual network computing ( hVNC ) module along the lines of  DarkVNC , which allows attackers to gain remote access to an infected computer. "Xeno RAT is developed entirely from scratch, ensuring a unique and tailored approach to remote access tools," the developer  states  in the project description. Another notable aspect is that it has a builder that enables the creation of bespoke variants of the malware.  It's worth noting that moom825 is a

A dormant package available on the Python Package Index (PyPI) repository was updated nearly after two years to propagate an information stealer malware called Nova Sentinel. The package, named  django-log-tracker , was first published to PyPI in April 2022, according to software supply chain security firm Phylum, which  detected  an anomalous update to the library on February 21, 2024. While the  linked GitHub repository  hasn't been updated since April 10, 2022, the introduction of a malicious update suggests a likely compromise of the PyPI account belonging to the developer. Django-log-tracker has been  downloaded 3,866 times  to date, with the rogue version (1.0.4) downloaded 107 times on the date it was published. The package is no longer available for download from PyPI. "In the malicious update, the attacker stripped the package of most of its original content, leaving only an __init__.py and example.py file behind," the company said. The changes, simple and

A financially motivated threat actor known as  UNC4990  is leveraging weaponized USB devices as an initial infection vector to target organizations in Italy. Google-owned Mandiant said the attacks single out multiple industries, including health, transportation, construction, and logistics. "UNC4990 operations generally involve widespread USB infection followed by the deployment of the EMPTYSPACE downloader," the company  said  in a Tuesday report. "During these operations, the cluster relies on third-party websites such as GitHub, Vimeo, and Ars Technica to host encoded additional stages, which it downloads and decodes via PowerShell early in the execution chain." UNC4990, active since late 2020, is assessed to be operating out of Italy based on the extensive use of Italian infrastructure for command-and-control (C2) purposes. It's currently not known if UNC4990 functions only as an initial access facilitator for other actors. The end goal of the threat

Cybersecurity researchers have identified malicious packages on the open-source Python Package Index (PyPI) repository that deliver an information stealing malware called WhiteSnake Stealer on Windows systems. The malware-laced packages are named nigpal, figflix, telerer, seGMM, fbdebug, sGMM, myGens, NewGends, and TestLibs111. They have been uploaded by a threat actor named "WS." "These packages incorporate Base64-encoded source code of PE or other Python scripts within their setup.py files," Fortinet FortiGuard Labs  said  in an analysis published last week. "Depending on the victim devices' operating system, the final malicious payload is dropped and executed when these Python packages are installed." While Windows systems are infected with WhiteSnake Stealer, compromised Linux hosts are served a Python script designed to harvest information. The activity, which predominantly targets Windows users, overlaps with a  prior campaign  that JFrog

Two malicious packages discovered on the npm package registry have been found to leverage GitHub to store Base64-encrypted SSH keys stolen from developer systems on which they were installed. The modules named  warbeast2000  and  kodiak2k  were published at the start of the month, attracting  412  and  1,281 downloads  before they were taken down by the npm maintainers. The most recent downloads occurred on January 21, 2024. Software supply chain security firm ReversingLabs, which made the discovery, said there were eight different versions of warbeast2000 and more than 30 versions of kodiak2k. Both the modules are designed to run a postinstall script after installation, each capable of retrieving and executing a different JavaScript file. While warbeast2000 attempts to access the private SSH key, kodiak2k is designed to look for a key named "meow," raising the possibility that the threat actor likely used a placeholder name during the early stages of the development.

Several public and popular libraries abandoned but still used in Java and Android applications have been found susceptible to a new software supply chain attack method called MavenGate. "Access to projects can be hijacked through domain name purchases and since most default build configurations are vulnerable, it would be difficult or even impossible to know whether an attack was being performed," Oversecured  said  in an analysis published last week. Successful exploitation of these shortcomings could allow nefarious actors to hijack artifacts in dependencies and inject malicious code into the application, and worse, even compromise the build process through a malicious plugin. The mobile security firm added that all Maven-based technologies, including Gradle, are vulnerable to the attack, and that it sent reports to more than 200 companies, including Google, Facebook, Signal, Amazon, and others. Apache Maven is  chiefly used  for building and managing Java-based projec

Continuous integration and continuous delivery (CI/CD) misconfigurations discovered in the open-source  TensorFlow  machine learning framework could have been exploited to orchestrate  supply chain attacks . The misconfigurations could be abused by an attacker to "conduct a supply chain compromise of TensorFlow releases on GitHub and PyPi by compromising TensorFlow's build agents via a malicious pull request," Praetorian researchers Adnan Khan and John Stawinski  said  in a report published this week. Successful exploitation of these issues could permit an external attacker to upload malicious releases to the GitHub repository, gain remote code execution on the self-hosted GitHub runner, and even retrieve a GitHub Personal Access Token (PAT) for the  tensorflow-jenkins user . TensorFlow uses GitHub Actions to automate the software build, test, and deployment pipeline. Runners, which refer to machines that execute jobs in a GitHub Actions workflow, can be either self-

GitHub has revealed that it has rotated some keys in response to a security vulnerability that could be potentially exploited to gain access to credentials within a production container. The Microsoft-owned subsidiary said it was made aware of the problem on December 26, 2023, and that it addressed the issue the same day, in addition to rotating all potentially exposed credentials out of an abundance of caution. The rotated keys include the GitHub commit signing key as well as GitHub Actions, GitHub Codespaces, and Dependabot customer encryption keys, necessitating users who rely on these keys to import the new ones. There is no evidence that the high-severity vulnerability, tracked as  CVE-2024-0200  (CVSS score: 7.2), has been previously found and exploited in the wild. "This vulnerability is also present on GitHub Enterprise Server (GHES)," GitHub's Jacob DePriest  said . "However, exploitation requires an authenticated user with an  organization owner role

Threat actors have been observed leveraging a now-patched security flaw in Microsoft Windows to deploy an open-source information stealer called  Phemedrone Stealer . "Phemedrone targets web browsers and data from cryptocurrency wallets and messaging apps such as Telegram, Steam, and Discord," Trend Micro researchers Peter Girnus, Aliakbar Zahravi, and Simon Zuckerbraun  said . "It also takes screenshots and gathers system information regarding hardware, location, and operating system details. The stolen data is then sent to the attackers via Telegram or their command-and-control (C&C) server." The attacks leverage  CVE-2023-36025  (CVSS score: 8.8), a security bypass vulnerability in Windows SmartScreen, that could be exploited by tricking a user into clicking on a specially crafted Internet Shortcut (.URL) or a hyperlink pointing to an Internet Shortcut file. The actively-exploited shortcoming was  addressed  by Microsoft as part of its November 2023 Patch Tuesday updates.

The ubiquity of GitHub in information technology (IT) environments has made it a lucrative choice for threat actors to host and deliver malicious payloads and act as  dead drop resolvers , command-and-control, and data exfiltration points. "Using GitHub services for malicious infrastructure allows adversaries to blend in with legitimate network traffic, often bypassing traditional security defenses and making upstream infrastructure tracking and actor attribution more difficult," Recorded Future  said  in a report shared with The Hacker News. The cybersecurity firm described the approach as "living-off-trusted-sites" (LOTS), a spin on the living-off-the-land (LotL) techniques often adopted by threat actors to conceal rogue activity and fly under the radar. Prominent among the methods by which GitHub is  abused   relates  to  payload   delivery , with some actors leveraging its features for command-and-control (C2) obfuscation. Last month, ReversingLabs  detailed  a number of rogue

Collaboration is a powerful selling point for SaaS applications. Microsoft, Github, Miro, and others promote the collaborative nature of their software applications that allows users to do more. Links to files, repositories, and boards can be shared with anyone, anywhere. This encourages teamwork that helps create stronger campaigns and projects by encouraging collaboration among employees dispersed across regions and departments.  At the same time, the openness of data SaaS platforms can be problematic. A  2023 survey  by the Cloud Security Alliance and Adaptive Shield found that 58% of security incidents over the last two years involved data leakage. Clearly, sharing is good, but data sharing must be put in check. Most SaaS applications have mechanisms to control sharing. These tools are quite effective in ensuring that company resources aren't open for display on the public web. This article will look at three common data leakage scenarios and recommend best practices for safe sh
