Weird ways to hide shellcode

A Bugcrowd red team manager discusses the challenge of concealing malware payloads from endpoint detection and response tools during authorized adversary simulations, framing loader design around software pretexting, payload hiding, and execution. The post explains that shellcode, often used for command-and-control implants or demonstration payloads such as launching Calculator, is commonly detected when stored plainly, leading practitioners to use approaches including encryption, remote hosting, and steganography. It presents a conceptual obfuscation technique that stores payload bytes along a uniquely determined shortest path through a generated maze, while unrelated cells contain decoy data. The maze is designed with reachable cells, optional loops, selected start and end points, and a pruned path so a pathfinding algorithm can later recover the intended data reliably. Demonstrations use both text and shellcode, while the author notes practical constraints such as payload size, file entropy, execution after recovery, and the need for further refinement before real-world use.
