PyPI Repository | Breaking Cybersecurity News | The Hacker News

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

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

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,

Cybersecurity researchers have discovered two malicious packages on the Python Package Index (PyPI) repository that were found leveraging a technique called  DLL side-loading  to circumvent detection by security software and run malicious code. The packages, named  NP6HelperHttptest  and  NP6HelperHttper , were each downloaded  537  and  166 times , respectively, before they were taken down. "The latest discovery is an example of DLL sideloading executed by an open-source package that suggests the scope of software supply chain threats is expanding," ReversingLabs researcher Petar Kirhmajer  said  in a report shared with The Hacker News. The name NP6 is notable as it refers to a legitimate marketing automation solution made by ChapsVision. In particular, the fake packages are typosquats of NP6HelperHttp and NP6HelperConfig, which are helper tools published by one of ChapsVision's employees to PyPI. In other words, the goal is to trick developers searching for NP6Hel

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

Threat actors are increasingly making use of GitHub for malicious purposes through novel methods, including abusing secret Gists and issuing malicious commands via git commit messages. "Malware authors occasionally place their samples in services like Dropbox, Google Drive, OneDrive, and Discord to host second stage malware and sidestep detection tools," ReversingLabs researcher Karlo Zanki  said  in a report shared with The Hacker News. "But lately, we have observed the increasing use of the GitHub open-source development platform for hosting malware." Legitimate public services are  known  to be  used  by  threat actors  for hosting malware and acting as  dead drop resolvers  to fetch the actual command-and-control (C2) address. While using public sources for C2 does not make them immune to takedowns, they do offer the benefit of allowing threat actors to easily create attack infrastructure that's both inexpensive and reliable. This technique is sneaky

An unknown threat actor has been observed publishing typosquat packages to the Python Package Index (PyPI) repository for nearly six months with an aim to deliver malware capable of gaining persistence, stealing sensitive data, and accessing cryptocurrency wallets for financial gain. The 27 packages, which masqueraded as popular legitimate Python libraries, attracted thousands of downloads, Checkmarx said in a new report. A majority of the downloads originated from the U.S., China, France, Hong Kong, Germany, Russia, Ireland, Singapore, the U.K., and Japan. "A defining characteristic of this attack was the utilization of steganography to hide a malicious payload within an innocent-looking image file, which increased the stealthiness of the attack," the software supply chain security firm  said . Some of the packages are pyefflorer, pyminor, pyowler, pystallerer, pystob, and pywool, the last of which was planted on May 13, 2023. A common denominator to these packages is t

A new set of 48 malicious npm packages have been discovered in the npm repository with capabilities to deploy a reverse shell on compromised systems. "These packages, deceptively named to appear legitimate, contained obfuscated JavaScript designed to initiate a reverse shell on package install," software supply chain security firm Phylum  said . All the counterfeit packages have been published by an npm user named  hktalent  ( GitHub ,  X ). As of writing, 39 of the packages uploaded by the author are still available for download. The attack chain is triggered post the installation of the package via an install hook in the package.json that calls a JavaScript code to establish a  reverse shell  to rsh.51pwn[.]com. "In this particular case, the attacker published dozens of benign-sounding packages with several layers of obfuscation and deceptive tactics in an attempt to ultimately deploy a reverse shell on any machine that simply installs one of these packages,"

Three additional rogue Python packages have been discovered in the Package Index (PyPI) repository as part of an ongoing malicious software supply chain campaign called  VMConnect , with signs pointing to the involvement of North Korean state-sponsored threat actors. The  findings  come from ReversingLabs, which detected the packages tablediter, request-plus, and requestspro. First disclosed at the start of the month by the company and Sonatype,  VMConnect  refers to a collection of Python packages that mimic popular open-source Python tools to download an unknown second-stage malware. The latest tranche is no different, with ReversingLabs noting that the bad actors are disguising their packages and making them appear trustworthy by using typosquatting techniques to impersonate prettytable and requests and confuse developers. The nefarious code within tablediter is designed to run in an endless execution loop in which a remote server is polled periodically to retrieve and execute

Researchers have discovered a novel attack on the Python Package Index (PyPI) repository that employs compiled Python code to sidestep detection by application security tools. "It may be the first supply chain attack to take advantage of the fact that Python bytecode (PYC) files can be directly executed," ReversingLabs analyst Karlo Zanki  said  in a report shared with The Hacker News. The package in question is  fshec2 , which was removed from the third-party software registry on April 17, 2023, following responsible disclosure on the same day. PYC files are compiled bytecode files that are generated by the Python interpreter when a Python program is executed. "When a module is imported for the first time (or when the source file has changed since the current compiled file was created) a .pyc file containing the compiled code should be created in a __pycache__ subdirectory of the directory containing the .py file,"  explains  the Python documentation. The pa

A malicious Python package on the Python Package Index (PyPI) repository has been found to use Unicode as a trick to evade detection and deploy an info-stealing malware. The package in question, named  onyxproxy , was uploaded to PyPI on March 15, 2023, and comes with capabilities to harvest and exfiltrate credentials and other valuable data. It has since been taken down, but not before attracting a total of  183 downloads . According to software supply chain security firm Phylum, the package incorporates its malicious behavior in a setup script that's packed with thousands of seemingly legitimate code strings. These strings include a mix of bold and italic fonts and are still readable and can be parsed by the Python interpreter, only to activate the execution of the stealer malware upon installation of the package.  "An obvious and immediate benefit of this strange scheme is readability," the company  noted . "Moreover, these visible differences do not prevent

A malicious Python package uploaded to the Python Package Index (PyPI) has been found to contain a fully-featured information stealer and remote access trojan. The package, named  colourfool , was identified by Kroll's Cyber Threat Intelligence team, with the company calling the malware  Colour-Blind . "The 'Colour-Blind' malware points to the democratization of cybercrime that could lead to an intensified threat landscape, as multiple variants can be spawned from code sourced from others," Kroll researchers Dave Truman and George Glass  said  in a report shared with The Hacker News. colourfool, like  other rogue Python modules  discovered in recent months, conceals its malicious code in the setup script, which points to a ZIP archive payload hosted on Discord. The file contains a Python script (code.py) that comes with different modules designed to log keystrokes, steal cookies, and even disable security software. The malware, besides performing defense ev

Cybersecurity researchers are warning of "imposter packages" mimicking popular libraries available on the Python Package Index (PyPI) repository. The 41 malicious PyPI packages have been found to pose as typosquatted variants of legitimate modules such as HTTP, AIOHTTP, requests, urllib, and urllib3. The names of the packages are as follows: aio5, aio6, htps1, httiop, httops, httplat, httpscolor, httpsing, httpslib, httpsos, httpsp, httpssp, httpssus, httpsus, httpxgetter, httpxmodifier, httpxrequester, httpxrequesterv2, httpxv2, httpxv3, libhttps, piphttps, pohttp, requestsd, requestse, requestst, ulrlib3, urelib3, urklib3, urlkib3, urllb, urllib33, urolib3, xhttpsp "The descriptions for these packages, for the most part, don't hint at their malicious intent," ReversingLabs researcher Lucija Valentić  said  in a new writeup. "Some are disguised as real libraries and make flattering comparisons between their capabilities and those of known, legitimate

Malicious actors have published more than 451 unique Python packages on the official Python Package Index (PyPI) repository in an attempt to infect developer systems with  clipper malware . Software supply chain security company Phylum, which  spotted the libraries , said the ongoing activity is a follow-up to a campaign that was initially disclosed in November 2022. The initial vector entails using  typosquatting  to mimic popular packages such as beautifulsoup, bitcoinlib, cryptofeed, matplotlib, pandas, pytorch, scikit-learn, scrapy, selenium, solana, and tensorflow, among others. "After installation, a malicious JavaScript file is dropped to the system and executed in the background of any web browsing session," Phylum  said  in a report published last year. "When a developer copies a cryptocurrency address, the address is replaced in the clipboard with the attacker's address." This is achieved by creating a Chromium web browser extension in the Window

An active malware campaign is targeting the Python Package Index (PyPI) and npm repositories for Python and JavaScript with typosquatted and fake modules that deploy a ransomware strain, marking the latest security issue to affect software supply chains. The typosquatted Python packages all impersonate the popular  requests library : dequests, fequests, gequests, rdquests, reauests, reduests, reeuests, reqhests, reqkests, requesfs, requesta, requeste, requestw, requfsts, resuests, rewuests, rfquests, rrquests, rwquests, telnservrr, and tequests. According to  Phylum , the rogue packages embed source code that retrieves a Golang-based ransomware binary from a remote server depending on the victim's operating system and microarchitecture. Successful execution causes the victim's desktop background to be changed to an actor-controlled image that claims to the U.S. Central Intelligence Agency (CIA). It's also designed to encrypt files and demand a $100 ransom in cryptocurr

A malicious package discovered on the Python Package Index (PyPI) has been found employing a steganographic trick to conceal malicious code within image files. The package in question, named " apicolor ," was uploaded to the Python third-party repository on October 31, 2022, and described as a "Core lib for REST API," according to Israeli cybersecurity firm  Check Point . It has since been  taken down . Apicolor, like other  rogue packages  detected recently, harbors its malicious behavior in the setup script used to specify metadata associated with the package, such as its dependencies. This takes the form of a second package called "judyb" as well as a seemingly harmless PNG file ("8F4D2uF.png") hosted on Imgur, an image-sharing service. "The judyb code turned out to be a steganography module, responsible [for] hiding and revealing hidden messages inside pictures," Check Point explained. The attack chain entails using the judy

Multiple campaigns that distributed trojanized and typosquatted packages on the NPM open source repository have been identified as the work of a single threat actor dubbed LofyGang . Checkmarx said it discovered 199 rogue packages totaling thousands of installations, with the group operating for over a year with the goal of stealing credit card data as well as user accounts associated with Discord Nitro, gaming, and streaming services. "LofyGang operators are seen promoting their hacking tools in hacking forums, while some of the tools are shipped with a hidden backdoor," the software security company said in a report shared with The Hacker News prior to its publication. Various pieces of the attack puzzle have already been reported by  JFrog ,  Sonatype , and  Kaspersky  (which called it LofyLife), but the latest analysis pulls the various operations together under one organizational umbrella that Checkmarx is referring to as  LofyGang . Believed to be an organized c

More details have emerged about the operators behind the  first-known phishing campaign  specifically aimed at the Python Package Index (PyPI), the official third-party software repository for the programming language. Connecting it to a threat actor tracked as  JuiceLedger , cybersecurity firm SentinelOne, along with Checkmarx, described the group as a relatively new entity that surfaced in early 2022. Initial "low-key" campaigns are said to have involved the use of rogue Python installer applications to deliver a .NET-based malware called JuiceStealer that's engineered to siphon passwords and other sensitive data from victims' web browsers. The attacks received a significant facelift last month when the JuiceLedger actors  targeted PyPi package contributors  in a phishing campaign, resulting in the compromise of three packages with malware. "The supply chain attack on PyPI package contributors appears to be an escalation of a campaign begun earlier in th

In another finding that could expose developers to increased risk of a supply chain attack, it has emerged that nearly one-third of the packages in PyPI, the Python Package Index, trigger automatic code execution upon downloading them. "A worrying feature in pip/PyPI allows code to automatically run when developers are merely downloading a package," Checkmarx researcher Yehuda Gelb  said  in a technical report published this week. "Also, this feature is alarming due to the fact that a great deal of the malicious packages we are finding in the wild use this feature of code execution upon installation to achieve higher infection rates." One of the ways by which packages can be installed for Python is by executing the " pip install " command, which, in turn, invokes a file called "setup.py" that comes bundled along with the module. "setup.py," as the name implies, is a  setup script  that's used to specify metadata associated wit

The Python Package Index, PyPI, on Wednesday sounded the alarm about an ongoing phishing campaign that aims to steal developer credentials and inject malicious updates to legitimate packages. "This is the first known phishing attack against PyPI," the maintainers of the official third-party software repository  said  in a series of tweets. The social engineering attack entails sending security-themed messages that create a false sense of urgency by informing recipients that Google is implementing a mandatory validation process on all packages and that they need to click on a link to complete the validation before September, or risk getting their PyPI modules removed. Should an unsuspecting developer fall for the scheme, users are directed to a lookalike landing page that mimics PyPI's login page and is hosted on Google Sites, from where the entered credentials are captured and abused to unauthorizedly access the accounts and compromise the packages to include malware
