MITM Decryption
Summary: Galaxy (MITM Decryption) is a Burp Suite extension, version 3.3.7 by author outlaws-bai and last updated 18 December 2025, that automatically decrypts encrypted HTTP traffic in real-time so applications with encrypted communications can be tested as if they were plaintext. Users write custom hooks in Java, Python (Jython or GraalPy), or JavaScript to reverse-engineer and apply encryption and decryption logic, letting them intercept and modify traffic across all of Burp.
What's compelling: The extension is third-party code that PortSwigger states it makes no warranty about for quality or usefulness, yet it sits inside Burp intercepting and modifying traffic across the whole tool - so a security team's testing proxy becomes a place where someone else's decryption hooks run against live application data.
