→ View on GitHub`fileless-xec` is a penetration testing tool that enables stealthy execution of remote binary files directly in memory, avoiding disk write operations. It utilizes the `memfd_create` and `fexecve` system calls for secure execution, supports customizable program names, and can bypass network restrictions through ICMP and HTTP3. Notable features include self-removal after execution and the capability to execute binaries without prior installation dependencies on the target system.
