Supply chain attacks

npm ecosystem (keyv, cacheable, flat-cache, cache-manager, and 400+ packages) ◐Partly patched

In early August 2026 a Mini Shai-Hulud / CHAINDROP worm compromised keyv and related cache packages, then self-propagated via stolen npm tokens to 400+ packages (1B+ monthly downloads across the graph). Payload runs via preinstall (disabled by default on npm 12+), steals npm/GitHub/cloud/CI secrets, and republishes backdoored versions. Microsoft, Elastic, JFrog and Wiz published analyses.

AOMEI Backupper

Google Mandiant and ManageEngine reported that a threat actor tampered with AOMEI Backupper update servers mid-2026, pushing a backdoor to users across multiple countries. Disclosure clustered around Oct 16 2026.

Nx Nx Console

Nx Console contains an embedded malicious code vulnerability that allowed a malicious version of Nx Console to be published. The compromised extension fetched an obfuscated payload that could harvested credentials from multiple sources on disk and in memory. Added to CISA KEV on 2026-05-27.

npm @antv/*, timeago.js, related packages under atool ◐Partly patched

May 2026 wave of Mini Shai-Hulud compromised packages across Alibaba’s AntV visualization ecosystem and timeago.js (via npm account atool). Payload harvested CI secrets from GitHub Actions runner memory and dumped credentials to public GitHub repos. StepSecurity documented the ongoing spread.

TanStack-related npm packages / OpenAI employee endpoints

In May 2026 OpenAI confirmed two employee devices were breached as part of the broader TanStack Mini Shai-Hulud npm supply-chain campaign. OpenAI said customer data, production systems, IP and deployed software were not impacted.

Aqua Trivy, trivy-action, setup-trivy, Checkmarx AST/KICS GitHub Actions, related Docker/VS Code artifacts

Threat actors tracked as TeamPCP compromised Trivy releases and GitHub Actions (including trivy-action / setup-trivy), then expanded into Checkmarx AST and KICS Actions and related artifacts. Malware stole CI/CD credentials (exfil as tpcp.tar.gz). Microsoft, Sysdig, CSA Singapore and Checkmarx published guidance in March 2026.

ASUS Live Update

ASUS Live Update contains an embedded malicious code vulnerability client were distributed with unauthorized modifications introduced through a supply chain compromise. The modified builds could cause devices meeting specific targeting conditions to perform unintended actions. The impacted product could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization. Added to CISA KEV on 2025-12-17.

VS Code extensions on OpenVSX and the VS Code Marketplace

Koi Security found extensions on OpenVSX (and one on Microsoft's marketplace) carrying JavaScript hidden in invisible Unicode variation selectors. The malware stole npm, GitHub, Git and OpenVSX credentials to infect more extensions, went after crypto wallets, and set up SOCKS proxies and hidden VNC.

npm: eslint-config-prettier, eslint-plugin-prettier, synckit, @pkgr/core, napi-postinstall, is

A maintainer was phished through the typosquat domain npnjs.com. The attacker published malicious eslint-config-prettier versions whose install script ran node-gyp.dll on Windows, dropping the Scavenger infostealer. eslint-plugin-prettier, synckit, @pkgr/core, napi-postinstall and later the 'is' package were also hit.

reviewdog action-setup GitHub Action

reviewdog action-setup GitHub Action contains an embedded malicious code vulnerability that dumps exposed secrets to Github Actions Workflow Logs. Added to CISA KEV on 2025-03-24.

ultralytics (PyPI)

Attackers compromised the Ultralytics YOLO project's GitHub Actions workflows (by poisoning the Actions cache) and published ultralytics 8.3.41 and 8.3.42 to PyPI with an XMRig cryptominer. They later pushed 8.3.45 and 8.3.46 using a leftover PyPI API token. All four versions were removed. PyPI's analysis credits Trusted Publishing attestations with making the attack auditable.

@solana/web3.js (npm)

A publish-access account for @solana/web3.js was compromised. Malicious versions 1.95.6 and 1.95.7, live on npm from 15:20 to 20:25 UTC on 2024-12-03, exfiltrated private key material from apps and bots that handle keys directly. Non-custodial wallets were generally not affected. Fixed in 1.95.8.

@lottiefiles/lottie-player (npm)

A LottieFiles developer's npm access was abused to publish @lottiefiles/lottie-player 2.0.5, 2.0.6 and 2.0.7 on 2024-10-30. Sites loading the 'latest' build from CDNs like unpkg and jsDelivr showed a wallet-connect popup that tried to drain visitors' crypto wallets. LottieFiles unpublished the versions and released 2.0.8, a copy of 2.0.4.

polyfill.io CDN

The polyfill.io domain and GitHub account were bought in February 2024 by a Chinese company. The CDN, embedded via cdn.polyfill.io on more than 100,000 sites, then served malicious JavaScript that redirected some mobile visitors to a sports betting site. Sansec exposed it on 2024-06-25. Cloudflare began rewriting polyfill.io links to its own mirror, and Namecheap put the domain on hold.

Justice AV Solutions Viewer

Justice AV Solutions (JAVS) Viewer installer contains a malicious version of ffmpeg.exe, named fffmpeg.exe (SHA256: 421a4ad2615941b177b6ec4ab5e239c14e62af2ab07c6df1741e2a62223223c4). When run, this creates a backdoor connection to a malicious C2 server. Added to the CISA KEV catalog on 2024-05-29.

PyPI –No fix needed

PyPI temporarily stopped new user registrations and new project names for about a day because malicious users and packages outpaced what its small admin team could handle.

GitHub (github.com SSH)

GitHub's private RSA SSH host key for github.com was briefly exposed in a public repository. GitHub rotated it as a precaution, which meant anyone connecting over SSH with RSA saw a host key mismatch warning until they updated known_hosts.
