Python's popularity, readable syntax, and extensive third-party library ecosystem make it an attractive target for threat actors seeking to compromise developer devices and infrastructure. Malicious packages and supply-chain attacks are increasingly common, exploiting the trust built into Python's packaging ecosystem to execute payloads at the moment of installation, without any direct interaction from the victim. This blog examines the full lifecycle of a Python package, from hosting on repositories such as PyPI or custom web servers, through source and wheel distribution formats, to the final installation into virtual or system-wide Python environments. Each technique is assessed for persistence, supported build methods, and distribution compatibility. We conclude with practical defensive measures, including dependency auditing tools, version pinning strategies, installation time controls, and general best practices for minimizing supply-chain risk.Due to the friendly nature of its syntax, extensive capabilities, and wide range of libraries, Python’s adoption by the developer community has been steadily increasing. Both the StackOverflow Developer Survey and the first party package repository PyPi’s download stats indicate rapidly growing usage, especially for data science, AI, and backend projects. Python has a very vibrant community of modules that can be easily installed using various package indexes. Unfortunately, this convenience comes with an additional burden. Malicious packages and supply chain infection are also increasingly common, as threat actors attempt …
