Which versions of aliyun-python-sdk-v2 are malicious?

The following PyPI versions of aliyun-python-sdk-v2 are flagged malicious: 2.13.36. Treat any of these as compromised.

How do I remediate aliyun-python-sdk-v2 if I installed it?

aliyun-python-sdk-v2 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 aliyun-python-sdk-v2 — how do I know if it already compromised me?

If aliyun-python-sdk-v2 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.

Is aliyun-python-sdk-v2 part of a known attack campaign?

Yes — aliyun-python-sdk-v2 is associated with the 2026-02-alibabacloude, RLMA-2026-00058 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 aliyun-python-sdk-v2 across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for aliyun-python-sdk-v2 (version 2.13.36).

What this malware does

Series of packages impersonating Alibaba Cloud. Two oldest hide code to run obfuscated code, but are likely to be used as dependency as the obfuscated code is not inside. The newest describe similar functionality, but the inside is highly obfuscated. Package names closely reassemble names of real Alibaba packages

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

Campaign: 2026-02-alibabacloude
