tencent-cloud-python-sdkPyPI
Malicious code in tencent-cloud-python-sdk (PyPI) Remove it immediately and rotate any exposed credentials.
What this malware does
Attack targeted at users of Alibaba, AWS and Telegram via malicious packages published to PyPI.
The malicious code was hidden in strategicly chosen functions and would only trigger when these functions were called. The malicious code does not automatically run on install or import, helping the packages evade detection.
Malicious versions
Every published version of this package is considered malicious — remove it entirely.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for tencent-cloud-python-sdk (all published versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging tencent-cloud-python-sdk across your stack and pipelines.
If you installed it — respond
Remove tencent-cloud-python-sdk 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 tencent-cloud-python-sdk 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 tencent-cloud-python-sdk 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.
