TL;DR We walk through three low-level tricks—dynamic syscalls, Phantom DLL hollowing, and RW→RX direct execution—and show how layering them confuses most Endpoint Detection & Response platforms. All examples are in Go so you can adapt them quickly. GitHub - nullcult/GoGotBackContribute to nullcult/GoGotBack development by…
