Playing with Python Pickle #3

This post demonstrates how to construct malicious Python Pickle streams that execute arbitrary Python code during deserialization: it shows patterns using eval(compile(...)), manipulating globals to capture output, and using builtin calls (getattr, dict.get, apply) to return a single string result, with a step-by-step trace of the Pickle VM execution. The write-up focuses on techniques for turning dynamic Python execution into a Pickle payload that can perform remote command execution and retrieve command output, useful for attackers exploiting insecure Pickle processing.
