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.
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.
Escapes Python sandbox restrictions. Use when working with restricted Python eval/exec environments, sandbox escapes, filtered input challenges, or Python jail challenges.

Progress:
- [ ] Identify file type (file, xxd)
- [ ] Check metadata (exiftool)
- [ ] Search strings for flag
- [ ] Check for embedded data (binwalk)
- [ ] Try steganography tools
- [ ] Extract hidden content
