Background for this topic.
Python is a high-level, general-purpose programming language used for applications, automation, data processing, and security tooling. Its reference implementation, CPython, includes a standard library, while third-party packages extend the language for web services, networking, and system administration. Python’s broad deployment means vulnerabilities can affect both the interpreter and widely used libraries.
Security concerns include flaws in Python or dependencies, malicious or compromised packages introduced through typosquatting or dependency confusion, and unsafe application behavior. For example, deserializing untrusted data with pickle, evaluating untrusted expressions with eval, or constructing shell commands from unchecked input can enable code execution. Practitioners should inventory transitive dependencies, pin and review versions, use trusted package sources and integrity checks, apply security updates, and run services with least privilege. Python is also commonly used to automate scanning, analysis, and response, so those scripts require the same access control, code review, and secret-handling discipline as other production software.
Just as one crop of malware-laced software packages is taken down from the popular Python code repository, a new host arrives, looking to steal a raft of data.
The new packages were masquerading as one of the most popular open-source packages on PyPI
A dozen malicious Python packages were uploaded to the PyPi repository this weekend in a typosquatting attack that performs DDoS attacks on a Counter-Strike 1.6 server. [...]
A now-removed rogue package pushed to the official third-party software repository for Python has been found to deploy cryptominers on Linux systems
