Malicious code in cv-train (PyPI)
The cv-train package on PyPI contains malicious code that exfiltrates basic host information such as IP address and username upon installation or import. The package overrides the install command in setup.py to execute this malicious behavior. It serves no legitimate purpose beyond this data exfiltration.
AI Analysis
Technical Summary
The cv-train PyPI package versions 0.0.5 and 99.0.0 include code that, when installed or imported, collects basic system information like IP address and username and sends it to an external party. This is achieved by overriding the install command in the package's setup.py file to run malicious code during installation. The package does not provide any legitimate functionality and is designed solely for data exfiltration.
Potential Impact
The impact is limited to the exfiltration of basic system information such as IP address and username. There is no indication of further malicious activity or system compromise beyond this data leakage. No known exploits in the wild have been reported.
Mitigation Recommendations
No official patch or remediation is available. Users should avoid installing or importing the cv-train package versions 0.0.5 and 99.0.0 from PyPI. Review and verify the source and integrity of packages before installation to prevent execution of malicious code.
