Vapor is a penetration testing tool designed for authorized security assessments. The following behaviors are features, not bugs:

• Reverse shell functionality over encrypted channels
• ChaCha20-Poly1305 authenticated encryption
• PEB walking and dynamic API resolution
• Hell's Gate syscall number extraction
• Indirect syscall execution via ntdll gadgets
• Early Bird APC thread injection
• Process injection into suspended processes
• Position-independent shellcode generation

These capabilities exist by design for legitimate security testing. Reports that simply describe Vapor working as intended will be closed.

Vapor is intended for authorized penetration testing, security research, and educational purposes only. Users are responsible for ensuring they have proper authorization before using this tool against any systems.
