Malicious VS Code Extensions and Supply‑Chain Packages

🔒 Security researchers uncovered malicious extensions on the Microsoft Visual Studio Code Marketplace that delivered stealer malware while posing as a dark theme and an AI assistant. Koi Security reported the extensions downloaded additional payloads, captured screenshots, and siphoned emails, Slack messages, Wi‑Fi passwords, clipboard contents and browser sessions to attacker servers. Microsoft removed the packages in early December 2025 after investigators linked them to a publisher using multiple similarly named packages.

Shai-Hulud 2.0 NPM malware exposed 400,000 developer secrets

🔒 Wiz researchers say the second Shai-Hulud NPM malware wave infected hundreds of packages and exposed roughly 400,000 raw secrets across some 30,000 GitHub repositories. Although TruffleHog verified about 10,000 secrets, Wiz found over 60% of leaked NPM tokens still valid as of Dec 1, leaving active credentials at risk. The payload propagated via the preinstall event (node setup_bun.js), affected over 800 package versions, and included a conditional destructive home-directory wipe. A small number of packages — notably @postman/tunnel-agent@0.6.7 and @asyncapi/specs@6.8.3 — represented the bulk of infections, indicating targeted mitigation could have sharply reduced impact.

North Korean Actors Push 197 Malicious npm Packages in Campaign

🛡️ North Korean threat actors tied to the Contagious Interview campaign have uploaded 197 malicious npm packages designed to deliver a variant of OtterCookie that incorporates features of BeaverTail. Socket reports the packages have been downloaded over 31,000 times and include loader names such as bcryptjs-node, cross-sessions, json-oauth and tailwind-magic. The payload evades sandboxes and virtual machines, profiles hosts, fetches a cross-platform binary via a hard-coded Vercel URL, opens a C2 remote shell, and can steal clipboard contents, keystrokes, screenshots, browser credentials, documents and cryptocurrency seed phrases.

Shai-Hulud 2.0: Inside a Major npm Supply-Chain Attack

🧨 Check Point Research details the Shai-Hulud 2.0 campaign, a rapid and extensive npm supply-chain attack observed in November 2025. Between 21–23 November attackers compromised hundreds of npm packages and over 25,000 GitHub repositories by abusing the npm preinstall lifecycle script to execute payloads before installation completed. The report outlines techniques, scale, and practical mitigations to help organizations protect development pipelines.

Shai-Hulud Worm Resurfaces, Infects Hundreds of npm Packages

🐛 Security teams have warned of a rapidly spreading secret-stealing worm, Shai-Hulud, that has resurfaced in the npm ecosystem and already infected hundreds of packages with tens of millions of downloads. First seen in September, attackers hijack developer accounts to publish trojanized packages that exfiltrate AWS keys and GitHub tokens to attacker-controlled repositories. Vendors including Wiz Security and Mondoo report explosive scaling—hundreds of new repos discovered every 30 minutes—and urge urgent dependency audits. Recommended mitigations include rotating credentials, disabling npm postinstall scripts in CI, enforcing MFA, pinning versions, and using tools like Safe-Chain to block malicious packages.

Shai-Hulud 2.0 Worm Spreads Through npm and GitHub

⚠️ Researchers at Wiz, JFrog and others are tracking a renewed campaign of the Shai‑Hulud credentials‑stealing worm spreading through the npm registry and GitHub. The new Shai‑Hulud 2.0 executes during the preinstall phase, exfiltrates developer and CI/CD secrets to randomized repositories, and injects malicious payloads into other packages. Widely used modules, including @asyncapi/specs, Zapier, Postman and others, have been compromised, prompting immediate remediation steps for affected developers and organizations.

Shai-Hulud Malware Hits Hundreds of npm Packages, Leaks Secrets

⚠️ Hundreds of trojanized versions of popular npm packages — including toolkits linked to Zapier, ENS Domains, PostHog and others — have been published in a renewed Shai‑Hulud supply‑chain campaign designed to steal developer and CI/CD secrets. The malware runs during pre‑install, collects credentials into files like cloud.json and environment.json, and posts encoded data to quickly created GitHub repositories. Researchers at Aikido Security, Wiz and Step Security identified obfuscated payloads in setup_bun.js and a large, heavily obfuscated bun_environment.js dropper.

Second Sha1-Hulud npm Wave Hits 25,000+ Repositories

⚠ Multiple security vendors report a second Sha1-Hulud campaign that has trojanized hundreds of npm packages and affected over 25,000 repositories. The attack leverages a preinstall script ("setup_bun.js") to install or locate the Bun runtime and execute a bundled payload ("bun_environment.js") that harvests credentials. The malware registers hosts as self-hosted GitHub runners named "SHA1HULUD", drops a vulnerable workflow (.github/workflows/discussion.yaml) to run arbitrary commands via repository discussions, exfiltrates secrets as artifacts, and then removes traces; when exfiltration fails it can attempt destructive wiping of the user home directory.

npm Malware Campaign Redirects Visitors to Fake Crypto Sites

🛡️ Researchers from the Socket Threat Research Team uncovered a new npm malware campaign operated by threat actor dino_reborn, distributed across seven packages that executed immediately and fingerprinted visitors. The packages used Adspect proxying and cloaking to distinguish researchers from victims, delivering branded fake CAPTCHAs and dynamic redirects to malicious crypto sites. Anti-analysis measures disabled developer tools and user interactions to hinder inspection.

Malicious npm Packages Use Adspect to Cloak Crypto Scams

⚠️Seven npm packages published under the developer name 'dino_reborn' were found leveraging the cloud-based Adspect service to distinguish researchers from potential victims and redirect targeted users to cryptocurrency scam pages. Socket's analysis shows six packages include a ~39 KB cloaking script that fingerprints visitors, employs anti-analysis controls, and forwards data to an actor-controlled proxy and the Adspect API. Targets are redirected to deceptive Ethereum and Solana-branded CAPTCHA pages, while likely researchers are shown a benign Offlido-style decoy.

Massive npm Worm Floods Registry to Harvest Tea Tokens

🔥 A coordinated worm is flooding the npm registry with packages designed to steal tokens from developers using the Tea Protocol, researchers say. Amazon and Sonatype report the campaign has expanded to roughly 153,000 packages, up from about 15,000 a year ago. While Tea tokens currently lack monetary value, experts warn threat actors could pivot to deliver malware or monetize rewards when Mainnet launches. Repositories and IT teams are urged to tighten access controls and deploy advanced detection.

Amazon Inspector: 150,000 npm Packages in Token Farming

🔍 Amazon Inspector researchers identified and reported over 150,000 npm packages tied to a coordinated tea.xyz token farming campaign that automatically generated and published packages to harvest blockchain rewards. The team combined rule-based detection with AI and worked directly with the Open Source Security Foundation (OpenSSF) to assign MAL‑IDs and submit packages for removal. The campaign caused registry pollution and reveals a new reward-driven supply chain abuse vector that can obscure legitimate software and consume infrastructure resources.

IndonesianFoods worm floods npm registry with spam packages

🔍 Security researchers have uncovered a large-scale, worm-like campaign targeting the npm registry. Dubbed IndonesianFoods, the operation has run for over two years and uses at least 11 npm accounts to publish tens of thousands of spam packages. Each package contains an auto.js or publishScript.js script that, when executed, forces packages public, randomizes versions and self-publishes in a loop. Endor Labs warns a single execution can produce ~12 packages per minute and the packages interlink as dependencies, creating exponential spread, registry strain and substantial supply-chain risk.

Over 46,000 Fake npm Packages Flood Registry Since 2024

📦 Researchers warn a large-scale spam campaign has flooded the npm registry with over 46,000 fake packages since early 2024, a coordinated, long-lived effort dubbed IndonesianFoods. The packages harbor a dormant worm in a single JavaScript file that only runs if a user manually executes commands like node auto.js, enabling automated self-publishing of thousands of junk packages. The campaign appears designed to waste registry resources, pollute search results, and possibly monetize via the Tea protocol; GitHub says it has removed the offending packages.

Typosquatted npm Package Targets GitHub Actions Builds

⚠️ A malicious npm package, @acitons/artifact, impersonated the legitimate @actions/artifact module and was uploaded on November 7 to specifically target GitHub Actions CI/CD workflows. It included a post-install hook that executed an obfuscated shell-script named "harness," which fetched a JavaScript payload (verify.js) to detect GitHub runners and exfiltrate build tokens. Using those tokens the attacker could publish artifacts and impersonate GitHub; the package accrued over 260,000 downloads across six versions before detection.

Malicious npm Package Typosquats GitHub Actions Artifact

🔍 Cybersecurity researchers uncovered a malicious npm package, @acitons/artifact, that typosquats the legitimate @actions/artifact package to target GitHub-owned repositories. Veracode says versions 4.0.12–4.0.17 included a post-install hook that downloaded and executed a payload intended to exfiltrate build tokens and then publish artifacts as GitHub. The actor (npm user blakesdev) removed the offending versions and the last public npm release remains 4.0.10. Recommended actions include removing the malicious versions, auditing dependencies for typosquats, rotating exposed tokens, and hardening CI/CD supply-chain protections.

Critical RCE in expr-eval JavaScript Library, affects NPM

⚠️ A critical remote code execution vulnerability (CVE-2025-12735) has been disclosed in the popular expr-eval JavaScript expression parser, which sees over 800,000 weekly downloads on NPM. Reported by Jangwoo Choe and rated 9.8 by CISA, the flaw stems from insufficient validation of the variables/context object passed to Parser.evaluate(), allowing attacker-supplied function objects to be invoked during evaluation. Both the original project and its maintained fork are affected; the fork provides a fix in v3.0.0. Developers should migrate to the patched fork and republish dependent packages immediately.

Malicious VS Code Extension and Trojanized npm Packages

⚠️ Researchers flagged a malicious Visual Studio Code extension named susvsex that auto-zips, uploads and encrypts files on first launch and uses GitHub as a command-and-control channel. Uploaded on November 5, 2025 and removed from Microsoft's VS Code Marketplace the next day, the package embeds GitHub access tokens and writes execution results back to a repository. Separately, Datadog disclosed 17 trojanized npm packages that deploy the Vidar infostealer via postinstall scripts.

Malicious npm Packages Use Invisible URL Dependencies

🔍 Researchers at Koi Security uncovered a campaign, PhantomRaven, that has contaminated 126 packages in Microsoft's npm repository by embedding invisible HTTP URL dependencies. These remote links are not fetched or analyzed by typical dependency scanners or npmjs.com, making packages appear to have 0 Dependencies while fetching malicious code at install time. The attackers aim to exfiltrate developer credentials and environment details, and they also exploit AI hallucinations to create plausible package names.
