What it does

You get PEB walking patterns for Windows API resolution, ROR13 hashing, null-byte avoidance tricks, and concrete allocation strategies that favor RW-then-RX over the RWX pattern EDRs flag. The loader section is strong, covering everything from fiber execution to certificate table hiding and the DripLoader pattern using syscalls. Includes cross-platform notes for Linux, macOS, and Windows on ARM64. This is red team tooling for when msfvenom payloads won't cut it and you need custom shellcode that evades modern defenses. Updated for Windows 11 24H2 AMSI heap scanning.
