Which versions of tencentcloud-python-sdk are malicious?

Every published version of tencentcloud-python-sdk on PyPI is considered malicious. Remove the package entirely.

How do I remediate tencentcloud-python-sdk if I installed it?

tencentcloud-python-sdk 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 tencentcloud-python-sdk — how do I know if it already compromised me?

If tencentcloud-python-sdk was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

How do I find tencentcloud-python-sdk across my projects, lockfiles, and CI pipelines?
