dirDevil: Hiding Code and Content Within Folder Structures

This post demonstrates a proof-of-concept method for hiding data in directory structures by encoding payloads as hexadecimal segments formatted into GUID-like folder names and reconstructing them with PowerShell. It explains chunking, indexing, padding, path-length limits, encoder/decoder scripts, and evaluates pros/cons including AV/EDR evasion potential, compression overhead, and practical limitations, concluding the technique is interesting but of limited real-world utility.
