Which versions of python-walletlibr-v are malicious?

The following PyPI versions of python-walletlibr-v are flagged malicious: 0.7.9. Treat any of these as compromised.

How do I remediate python-walletlibr-v if I installed it?

python-walletlibr-v 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 python-walletlibr-v — how do I know if it already compromised me?

If python-walletlibr-v 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 python-walletlibr-v part of a known attack campaign?

Yes — python-walletlibr-v is associated with the IN-MAL-2026-018733 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 python-walletlibr-v across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for python-walletlibr-v (version 0.7.9).

What this malware does

python-walletlibr-v is a wallet-lookalike PyPI package that ships no wallet functionality — only a stub hello() that prints 'Hello from my custom library!' and placeholder author metadata (author = 'Your Name'). Its setup.py registers a CustomInstall command that, on Windows at pip install time, writes a.bat file into %TEMP%, spawns a new cmd.exe console to execute it via subprocess.Popen(['cmd.exe','/k', bat_path], CREATE_NEW_CONSOLE), and calls os.system('calc'). Arbitrary local command execution fires automatically during pip install on Windows hosts, unrelated to any advertised functionality.
