Malicious package

abuden216npm

abuden216 is a confirmed malicious npm package (MAL-2026-10259) that opens a backdoor for remote access (malicious versions 1.1.7, 1.7.7, 2.0.0). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall abuden216

What this malware does

The tarball ships auto-publish.sh, a script that republishes the same payload under ~100 distinct npm names (ishowfeet1-ishowfeet20, nottuff1-nottuff30, abuden*, imillegal*, ratelimitsucks*, etc/) by rewriting package.json.name and running npm publish --silent in a loop — namespace-spam infrastructure shipped inside the package itself. The package's declared main is sw.js, a browser Service Worker (importScripts('./8cfc2/hgshm.js'), self.addEventListener('install'|'activate'|'fetch'|'message')) that throws immediately if loaded from Node. The shipped assets are a heavily obfuscated Ultraviolet/bare-mux web-proxy frontend with an index.html themed as "Riverbend Tutoring" that hides a popunder redirect to https://abdct.com/ on click/keydown/touchstart. package.json declares no preinstall/install/postinstall/prepare hooks, and require('ishowfeet9') from Node fails before any code runs, so a Node installer experiences no auto-execution. The harm is registry abuse (mass-publication of a misleading name family) and a browser-side proxy/popunder served to whoever later loads these static assets — not installer-side compromise. Routing to human review for namespace-abuse adjudication.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Detection & response playbook

Backdoor / remote access
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for abuden216 (3 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging abuden216 across your stack and pipelines.

  2. If you installed it — respond

    abuden216 establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

  3. Did it already run?

    If abuden216 was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

  4. How O3 protects you

    O3 blocks abuden216 before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Frequently asked questions

No. abuden216 on npm has been identified as a malicious package (versions 1.1.7, 1.7.7, 2.0.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
