Completed the Browsed machine on Hack The Box 🚀

Gained initial access by uploading a malicious Chrome extension with a reverse shell payload. Automated testing executed it, giving a foothold as larry and access to user flag.

Escalated privileges by abusing a misconfigured sudo rule on extension_tool.py. A world-writable pycache directory allowed bytecode poisoning, leading to root access and full compromise.

Great box for practicing client-side attacks, extension abuse, and privilege escalation via Python internals.
