The accesspdp package version 2.0.1 published on PyPI was identified as malicious by both the kam193 security researcher and the OpenSSF Package Analysis project. The package contains code designed to exfiltrate basic system information including IP address and username upon installation or module import.\n\nThe malicious behavior is implemented by overriding the install command in setup.py, causing the payload to execute during the package installation process. This is a direct supply chain compromise where the malicious code is embedded in the package itself.\n\nThe OpenSSF Package Analysis project formally classified the package as malicious and documented it in their malicious-packages repository. The incident was categorized as a typical pentest-style package with limited but real harm potential due to the data exfiltration capability.\n\nThe package has been identified and removed from active distribution, with the incident now resolved through detection and public disclosure.
