A Go implementation of copyfail (CVE-2026-31431)
A fileless C2 framework written in pure x64 Linux Assembly with zero libc dependencies. Features dynamic protocol pivoting between raw ICMP sockets and DNS (UDP/53) via in-memory VTable manipulation. 100% direct syscalls, no disk writes, and strict mathematical packet authentication.
Phantom-Evasion-Loader is a standalone, pure x64 Assembly injection engine engineered to minimize the detection surface of modern EDR/XDR solutions and Kernel-level monitors like Falco (eBPF). It leverages advanced techniques such as SROP and Zero-Copy Injection to deliver payloads as a ghost in the machine.
