Veil is an open-source framework designed to generate Metasploit payloads that bypass common antivirus solutions, pre-installed on Kali Linux at /usr/share/veil. Developed by Chris Truncer and maintained by the Veil-Framework community, it consists of two main tools: Veil-Evasion for creating undetectable executables and Veil-Ordnance for generating custom shellcode. Veil leverages languages like Python, C, Go, and PowerShell to produce payloads for Windows, Linux, and macOS, integrating with Metasploit for penetration testing. Its obfuscation techniques and encryption options make it a critical tool for ethical hackers and red teamers.
