Which versions of timemcplib are malicious?

The following PyPI versions of timemcplib are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate timemcplib if I installed it?

timemcplib is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

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

If timemcplib 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 timemcplib part of a known attack campaign?

Yes — timemcplib is associated with the 2026-04-process-support 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 timemcplib 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 timemcplib (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 timemcplib across your stack and pipelines.

Malicious package

Malicious code in timemcplib (PyPI) Remove it immediately and rotate any exposed credentials.

MAL-2026-3238

Immediate action

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

pip uninstall timemcplib

What this malware does

During import, the package automatically downloads and executes code that first acts as an infostealer and then starts code acting as a RAT. It connects with a hardcoded C2 server and waits for commands, supporting e.g. executing remote commands, exfiltrating files, recording the screen, executing GUI actions through PyAutoGUI.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2026-04-process-support

Reasons (based on the campaign):

exfiltration-generic
The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.
rat
spyware-like
infostealer
persistence
exfiltration-browser-data
exfiltration-crypto
files-exfiltration

Detection & response playbook

Credential / info stealer

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for timemcplib (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 timemcplib across your stack and pipelines.
If you installed it — respond
timemcplib is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If timemcplib 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 timemcplib 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
