Which versions of tibcwmpoeafh are malicious?

The following npm versions of tibcwmpoeafh are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate tibcwmpoeafh if I installed it?

Remove tibcwmpoeafh from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

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

If tibcwmpoeafh 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 tibcwmpoeafh part of a known attack campaign?

Yes — tibcwmpoeafh is associated with the GHSA-vcg8-c5h2-55w6, IN-MAL-2026-020472 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 tibcwmpoeafh 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 tibcwmpoeafh (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging tibcwmpoeafh across your stack and pipelines.

Immediate action

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

npm uninstall tibcwmpoeafh

What this malware does

The package was found to contain malicious code or consuming dependency that contains malicious code

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.

Malicious package

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for tibcwmpoeafh (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging tibcwmpoeafh across your stack and pipelines.
If you installed it — respond
Remove tibcwmpoeafh from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If tibcwmpoeafh 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 tibcwmpoeafh 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.
