Typosquatted npm Packages Deliver Cross-Platform Stealer

🚨 A multi-stage supply-chain campaign published ten typosquatted npm packages on July 4 that collectively reached nearly 10,000 downloads before removal, according to Socket. Each package abused npm’s postinstall lifecycle to open a new terminal, present a fake CAPTCHA prompt, and retrieve a PyInstaller-packed binary that harvests credentials from browsers, OS keyrings, SSH keys, tokens and cloud configuration files. The JavaScript installers combined four layers of obfuscation with social engineering to evade detection and delay scrutiny while exfiltrating collected secrets to the attacker’s host.

PhantomRaven: Malware in 126 npm Packages Steals Tokens

⚠️ Koi Security has identified a supply-chain campaign dubbed PhantomRaven that inserted malicious code into 126 npm packages, collectively installed more than 86,000 times, by pointing dependencies to an attacker-controlled host (packages.storeartifact[.]com). The packages include preinstall lifecycle hooks that fetch and execute remote dynamic dependencies, enabling immediate execution on developers' machines. The payloads are designed to harvest GitHub tokens, CI/CD secrets, developer emails and system fingerprints, and exfiltrate the results, while typical scanners and dependency analyzers miss the remote dependencies because npmjs.com does not follow those external URLs.

Typosquatted npm Packages Deploy Cross-Platform Infostealer

🚨 Ten typosquatted packages on npm were found delivering a 24 MB PyInstaller infostealer that targets Windows, Linux, and macOS. Uploaded on July 4 and downloaded nearly 10,000 times, the packages used heavy obfuscation and a fake CAPTCHA to evade detection. Researchers at Socket say the malware harvests keyrings, browser credentials, SSH keys and API tokens, then exfiltrates data to a remote server. Developers who installed these packages should remove them, perform remediation, and rotate all secrets.

PhantomRaven campaign floods npm with credential theft

🐦 The PhantomRaven campaign distributes dozens of malicious npm packages that steal authentication tokens, CI/CD secrets, and GitHub credentials. Discovered by Koi Security, the activity began in August and involved 126 packages with over 86,000 downloads. The packages use a remote dynamic dependency mechanism to fetch and execute payloads during npm install, enabling stealthy credential exfiltration. Developers should verify package provenance and avoid unvetted LLM-generated package suggestions.

PhantomRaven npm Campaign Uses Invisible Dependencies

🕵️ Researchers at Koi Security uncovered an ongoing npm credential-harvesting campaign called PhantomRaven, active since August 2025, that steals npm tokens, GitHub credentials and CI/CD secrets. The attacker hides malicious payloads using Remote Dynamic Dependencies (RDD), fetching code from attacker-controlled servers at install time to bypass static scans. The campaign leveraged slopsquatting—typo variants that exploit AI hallucinations—to increase installs; Koi found 126 infected packages with about 20,000 downloads and at least 80 still live at publication.

Malicious npm Packages Steal Developer Credentials

⚠️ Security researchers revealed 10 typosquatted npm packages uploaded on July 4, 2025, that install a cross-platform information stealer targeting Windows, macOS, and Linux. The packages impersonated popular libraries and use a postinstall hook to open a terminal, display a fake CAPTCHA, fingerprint victims, and download a 24MB PyInstaller stealer. The obfuscated JavaScript fetches a data_extracter binary from an attacker server, harvests credentials from browsers, system keyrings, SSH keys and config files, compresses the data into a ZIP, and exfiltrates it to the remote host.

Cloudflare Page Shield Thwarted npm Supply-Chain Attack

🛡️ In early September 2025 attackers published malicious releases to 18 widely used npm packages, enabling crypto‑stealing and token exfiltration. Cloudflare's Page Shield static analysis and ML pipeline — including an MPGCN on JavaScript ASTs — inspects 3.5 billion scripts per day and would have detected these compromised packages. Inference completes in under 0.3s and ensemble review reduces false positives, protecting customers from similar supply‑chain threats.

Self-Propagating GlassWorm Targets VS Code Marketplaces

🪲 Researchers at Koi Security have uncovered GlassWorm, a sophisticated self-propagating malware campaign affecting extensions in the OpenVSX and Microsoft VS Code marketplaces. The worm hides executable payloads using Unicode variation selectors, harvests NPM, GitHub and Git credentials, drains 49 cryptocurrency wallets, and deploys SOCKS proxies and hidden VNC servers on developer machines. CISOs are urged to treat this as an immediate incident: inventory VS Code usage, monitor for anomalous outbound connections and long-lived SOCKS/VNC processes, rotate exposed credentials, and block untrusted extension registries.

North Korean Hackers Merge BeaverTail and OtterCookie

🔐 Cisco Talos reports that a North Korean-linked threat cluster has blended features of its BeaverTail and OtterCookie JavaScript malware families, with recent OtterCookie variants adding keylogging, screenshot capture, and clipboard monitoring. The intrusion chain observed involved a trojanized Node.js application called Chessfi and a malicious npm dependency published on August 20, 2025 that executed postinstall hooks to launch multi-stage payloads. Talos tied the activity to the Contagious Interview recruitment scam and highlighted continued modularization and abuse of legitimate open-source packages and public Git hosting to distribute malicious code.

Merged BeaverTail and OtterCookie Tooling Observed in Attacks

🔍 Talos uncovered a campaign linked to the DPRK-aligned cluster Famous Chollima that used a trojanized Node.js package and a malicious VS Code extension to deliver merged BeaverTail and OtterCookie tooling. The combined JavaScript payloads include a newly observed keylogger and screenshot module alongside clipboard theft, targeted file exfiltration, remote shell access, and cryptocurrency extension stealing. Indicators, C2 addresses, Snort/ClamAV detections, and mitigation guidance are provided.

Malicious npm, PyPI and RubyGems Packages Use Discord C2

⚠️ Researchers at a software supply chain security firm found multiple malicious packages across npm, PyPI, and RubyGems that use Discord webhooks as a command-and-control channel to exfiltrate developer secrets. Examples include npm packages that siphon config files and a Ruby gem that sends host files like /etc/passwd to a hard-coded webhook. The investigators warn that webhook-based C2 is cheap, fast, and blends into normal traffic, enabling early-stage compromise via install-time hooks and build scripts. The disclosure also links a large North Korean campaign that published hundreds of malicious packages to deliver stealers and backdoors.

175 Malicious npm Packages Used in Large-Scale Phishing

⚠️ Researchers have identified 175 malicious packages on the npm registry used as infrastructure for a widespread phishing campaign called Beamglea. The packages, collectively downloaded about 26,000 times, host redirect scripts served via unpkg.com that route victims to credential-harvesting pages. Attackers automated package publication and embedded victim-specific emails into generated HTML, pre-filling login fields to increase the likelihood of successful credential capture.

First Malicious MCP Server Found in NPM Postmark Package

🛡️ Cybersecurity researchers at Koi Security reported the first observed malicious Model Context Protocol (MCP) server embedded in an npm package, a trojanized copy of the postmark-mcp library. The malicious change, introduced in version 1.0.16 in September 2025 by developer "phanpak", added a one-line backdoor that BCCs every outgoing email to phan@giftshop[.]club. Users who installed the package should remove it immediately, rotate any potentially exposed credentials, and review email logs for unauthorized BCC activity.

MCP supply-chain attack via squatted Postmark connector

🔒 A malicious npm package, postmark-mcp, was weaponized to stealthily copy outgoing emails by inserting a hidden BCC in version 1.0.16. The package impersonated an MCP Postmark connector and forwarded every message to an attacker-controlled address, exposing password resets, invoices, and internal correspondence. The backdoor was a single line of code and remained available through regular downloads before the package was removed. Koi Security advises immediate removal, credential rotation, and audits of all MCP connectors.

Threatsday Bulletin: Rootkits, Supply Chain, and Arrests

🛡️ SonicWall released firmware 10.2.2.2-92sv for SMA 100-series appliances to add file checks intended to remove an observed rootkit, and moved SMA 100 end-of-support to 31 October 2025. The bulletin also flags an unpatched OnePlus SMS permission bypass (CVE-2025-10184), a GeoServer RCE compromise affecting a U.S. federal agency, and ongoing npm supply-chain and RAT campaigns. Defenders are urged to apply patches, rotate credentials, and enforce phishing-resistant MFA.

GitHub Tightens npm Security: Mandatory 2FA, Token Limits

🔒 GitHub is implementing stronger defenses for the npm ecosystem after recent supply-chain attacks that compromised repositories and spread to package registries. The platform will require 2FA for local publishing, shorten token lifetimes to seven days, deprecate classic tokens and TOTP in favor of FIDO/WebAuth, and promote trusted publishing. Changes will roll out gradually with documentation and migration guides to reduce disruption.

npm Supply-Chain Worm 'Shai-Hulud' Compromises Packages

🛡️ CISA released an alert about a widespread software supply chain compromise affecting the npm registry: a self-replicating worm called 'Shai-Hulud' has compromised over 500 packages. The actor harvested GitHub Personal Access Tokens and cloud API keys for AWS, Google Cloud, and Azure, exfiltrating them to a public repository and using them to publish malicious package updates. CISA recommends immediate dependency reviews, credential rotation, enforcing phishing-resistant MFA, pinning package versions to releases before Sept. 16, 2025, hardening GitHub settings, and monitoring for anomalous outbound connections.

NPM package uses QR code to fetch cookie-stealing malware

🔒 A malicious npm package named fezbox was recently discovered using a QR code embedded in an image to retrieve a second-stage, cookie-stealing payload from the attacker's server. The package's minified code (notably in dist/fezbox.cjs) delays execution, avoids development environments, then decodes a reversed URL to fetch a dense JPG QR image containing obfuscated JavaScript. When the payload finds credentials in document.cookie it extracts username and password and exfiltrates them via an HTTPS POST; the package accrued at least 327 downloads before registry removal.

GitHub mandates 2FA, short-lived tokens for npm publishing

🔐 GitHub said it will change npm authentication and publishing practices in the near future to address recent supply-chain attacks, including the Shai-Hulud incident. The company will require 2FA for local publishes, deprecate legacy tokens and TOTP in favor of FIDO, introduce seven-day granular publishing tokens, and enable OIDC-based trusted publishing. The npm CLI will also auto-generate provenance attestations to prove source and build environment.

Shai-Hulud Worm: Large npm Supply Chain Compromise

🪱 Palo Alto Networks Unit 42 is investigating an active supply chain attack in the npm ecosystem driven by a novel self-replicating worm tracked as "Shai-Hulud." The malware has compromised more than 180 packages, including high-impact libraries such as @ctrl/tinycolor, and automates credential theft, repository creation, and propagation across maintainers' packages. Unit 42 assesses with moderate confidence that an LLM assisted in authoring the malicious bash payload. Customers are protected through Cortex Cloud, Prisma Cloud, Cortex XDR and Advanced WildFire, and Unit 42 recommends immediate credential rotation, dependency audits, and enforcement of MFA.
