Which versions of abuden226 are malicious?

The following npm versions of abuden226 are flagged malicious: 1.1.7, 1.7.7, 2.0.0. Treat any of these as compromised.

How do I remediate abuden226 if I installed it?

abuden226 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.

I already installed abuden226 — how do I know if it already compromised me?

If abuden226 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.

Is abuden226 part of a known attack campaign?

Yes — abuden226 is associated with the GHSA-fwjx-23mw-83cp, IN-MAL-2026-009928, IN-MAL-2026-009931, IN-MAL-2026-009930 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find abuden226 across my projects, lockfiles, and CI pipelines?

Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for abuden226 (3 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging abuden226 across your stack and pipelines.

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

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

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for abuden226 (3 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging abuden226 across your stack and pipelines.
If you installed it — respond
abuden226 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.
Did it already run?
If abuden226 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.
How O3 protects you
O3 blocks abuden226 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.
