Cybersecurity researchers have flagged a malicious package on the Python Package Index (PyPI) repository that claims to offer the ability to create a SOCKS5 proxy service, while also providing a stealthy backdoor-like functionality to drop additional payloads on Windows systems. The deceptive package, named soopsocks, attracted a total of 2,653 downloads before it was taken down. It was first uploaded by a user named " soodalpie " on September 26, 2025, the same date the account was created. "While providing this capability, it exhibits behavior as a backdoor proxy server targeting Windows platforms, using automated installation processes via VBScript or an executable version," JFrog said in an analysis. The executable ("_AUTORUN.EXE") is a compiled Go file that, besides including a SOCKS5 implementation as advertised, is also designed to run PowerShell scripts, set firewall rules, and relaunch itself with elevated permissions. It also carries out ...

Cybersecurity researchers have discovered what has been described as the first-ever instance of a malicious Model Context Protocol ( MCP ) server spotted in the wild, raising software supply chain risks. According to Koi Security, a legitimate-looking developer managed to slip in rogue code within an npm package called " postmark-mcp " that copied an official Postmark Labs library of the same name. The malicious functionality was introduced in version 1.0.16, which was released on September 17, 2025. The actual "postmark-mcp" library, available on GitHub , exposes an MCP server to allow users to send emails, access and use email templates, and track campaigns using artificial intelligence (AI) assistants. The npm package in question has since been deleted from npm by the developer " phanpak ," who uploaded it to the repository on September 15, 2025, and maintains 31 other packages. The JavaScript library attracted a total of 1,643 downloads. ...

GitHub on Monday announced that it will be changing its authentication and publishing options "in the near future" in response to a recent wave of supply chain attacks targeting the npm ecosystem, including the Shai-Hulud attack . This includes steps to address threats posed by token abuse and self-replicating malware by allowing local publishing with required two-factor authentication (2FA), granular tokens that will have a limited lifetime of seven days, and trusted publishing , which enables the ability to securely publish npm packages directly from CI/CD workflows using OpenID Connect (OIDC). Trusted publishing, besides eliminating the need for npm tokens, establishes cryptographic trust by authenticating each publish using short-lived, workflow-specific credentials that cannot be exfiltrated or reused. Even more significantly, the npm CLI automatically generates and publishes provenance attestations for the package. "Every package published via trusted publi...

Multiple npm packages have been compromised as part of a software supply chain attack after a maintainer's account was compromised in a phishing attack. The attack targeted Josh Junon (aka Qix ), who received an email message that mimicked npm ("support@npmjs[.]help"), urging them to update their update their two-factor authentication (2FA) credentials before September 10, 2025, by clicking on embedded link. The phishing page is said to have prompted the co-maintainer to enter their username, password, and two-factor authentication (2FA) token, only for it to be stolen likely by means of an adversary-in-the-middle ( AitM ) attack and used to publish the rogue version to the npm registry. The following 20 packages, which collectively attract over 2 billion weekly downloads, have been confirmed as affected as part of the incident - ansi-regex@6.2.1 ansi-styles@6.2.2 backslash@0.2.1 chalk@5.6.1 chalk-template@1.1.1 color-convert@3.1.1 color-name@2.0.1...

A new set of four malicious packages have been discovered in the npm package registry with capabilities to steal cryptocurrency wallet credentials from Ethereum developers. "The packages masquerade as legitimate cryptographic utilities and Flashbots MEV infrastructure while secretly exfiltrating private keys and mnemonic seeds to a Telegram bot controlled by the threat actor," Socket researcher Kush Pandya said in an analysis. The packages were uploaded to npm by a user named " flashbotts ," with the earliest library uploaded as far back as September 2023. The most recent upload took place on August 19, 2025. The packages in question, all of which are still available for download as of writing, are listed below - @flashbotts/ethers-provider-bundle (52 Downloads) flashbot-sdk-eth (467 Downloads) sdk-ethers (90 Downloads) gram-utilz (83 Downloads) The impersonation of Flashbots is not coincidental, given its role in combating the adverse effects of...

Cybersecurity researchers have discovered two new malicious packages on the npm registry that make use of smart contracts for the Ethereum blockchain to carry out malicious actions on compromised systems, signaling the trend of threat actors constantly on the lookout for new ways to distribute malware and fly under the radar. "The two npm packages abused smart contracts to conceal malicious commands that installed downloader malware on compromised systems," ReversingLabs researcher Lucija Valentić said in a report shared with The Hacker News. The packages, both uploaded to npm in July 2025 and no longer available for download, are listed below - colortoolsv2 (7 downloads) mimelib2 (1 download) The software supply chain security firm said the libraries are part of a larger and sophisticated campaign impacting both npm and GitHub, tricking unsuspecting developers into downloading and running them. While the packages themselves make no effort to conceal their malici...

Cybersecurity researchers have discovered a malicious npm package that comes with stealthy features to inject malicious code into desktop apps for cryptocurrency wallets like Atomic and Exodus on Windows systems. The package, named nodejs-smtp , impersonates the legitimate email library nodemailer with an identical tagline, page styling, and README descriptions, attracting a total of 347 downloads since it was uploaded to the npm registry in April 2025 by a user named "nikotimon." It's currently no longer available. "On import, the package uses Electron tooling to unpack Atomic Wallet's app.asar, replace a vendor bundle with a malicious payload, repackage the application, and remove traces by deleting its working directory," Socket researcher Kirill Boychenko said . The main objective is to overwrite the recipient address with hard-coded wallets controlled by the threat actor, redirecting Bitcoin (BTC), Ethereum (ETH), Tether (USDT and TRX USDT), XRP...

Cybersecurity researchers have discovered a loophole in the Visual Studio Code Marketplace that allows threat actors to reuse names of previously removed extensions. Software supply chain security outfit ReversingLabs said it made the discovery after it identified a malicious extension named "ahbanC.shiba" that functioned similarly to two other extensions – ahban.shiba and ahban.cychelloworld – that were flagged earlier this March. All three libraries are designed to act as a downloader to retrieve a PowerShell payload from an external server that encrypts files in a folder called "testShiba" on the victim's Windows desktop and demands a Shiba Inu token by instructing the victim to deposit the assets to an unspecified wallet. These efforts suggest ongoing development attempts by the threat actor. The company said it decided to dig deeper because of the fact that the name of the new extension ("ahbanC.shiba") was virtually the same as one of the t...

The maintainers of the nx build system have alerted users to a supply chain attack that allowed attackers to publish malicious versions of the popular npm package and other auxiliary plugins with data-gathering capabilities. "Malicious versions of the nx package, as well as some supporting plugin packages, were published to npm, containing code that scans the file system, collects credentials, and posts them to GitHub as a repo under the user's accounts," the maintainers said in an advisory published Wednesday. Nx is an open-source, technology-agnostic build platform that's designed to manage codebases. It's advertised as an "AI-first build platform that connects everything from your editor to CI [continuous integration]." The npm package has over 3.5 million weekly downloads. The list of affected packages and versions is below. These versions have since been removed from the npm registry. The compromise of the nx package took place on August 26, 20...

Cybersecurity researchers have discovered a malicious package in the Python Package Index (PyPI) repository that introduces malicious behavior through a dependency that allows it to establish persistence and achieve code execution. The package, named termncolor , realizes its nefarious functionality through a dependency package called colorinal by means of a multi-stage malware operation, Zscaler ThreatLabz said . While termncolor was downloaded 355 times, colorinal attracted 529 downloads. Both libraries are no longer available on PyPI. "This attack could leverage DLL side-loading to facilitate decryption, establish persistence, and conduct command-and-control (C2) communication, ending in remote code execution," according to researchers Manisha Ramcharan Prajapati and Satyam Singh. Once installed and executed, termncolor is designed to import colorinal, which, in turn, loads a rogue DLL that's responsible for decrypting and running the next-stage payload. Specifica...

Cybersecurity researchers have discovered a set of 11 malicious Go packages that are designed to download additional payloads from remote servers and execute them on both Windows and Linux systems. "At runtime the code silently spawns a shell, pulls a second-stage payload from an interchangeable set of .icu and .tech command-and-control (C2) endpoints, and executes it in memory," Socket security researcher Olivia Brown said . The list of identified packages is below - github.com/stripedconsu/linker github.com/agitatedleopa/stm github.com/expertsandba/opt github.com/wetteepee/hcloud-ip-floater github.com/weightycine/replika github.com/ordinarymea/tnsr_ids github.com/ordinarymea/TNSR_IDS github.com/cavernouskina/mcp-go github.com/lastnymph/gouid github.com/sinfulsky/gouid github.com/briefinitia/gouid

Cybersecurity researchers have flagged a malicious npm package that was generated using artificial intelligence (AI) and concealed a cryptocurrency wallet drainer. The package, @kodane/patch-manager, claims to offer "advanced license validation and registry optimization utilities for high-performance Node.js applications." It was uploaded to npm by a user named "Kodane" on July 28, 2025. The package is no longer available for download from the registry, but not before it attracted over 1,500 downloads. Software supply chain security company Safety, which discovered the library, said the malicious features are advertised directly in the source code, calling it an "enhanced stealth wallet drainer." Specifically, the behavior is triggered as part of a postinstall script that drops its payload within hidden directories across Windows, Linux, and macOS systems, and then proceeds to connect to a command-and-control (C2) server at "sweeper-monitor-produ...
