Loaders, sleep obfuscation, and the engineering trade-offs behind implants. Built to understand, not to ship.
How userland hooks work, how to remove them, and why the technique is less effective than the blogs suggest.
Classic injection, APC injection, and process hollowing with working code, compile commands, and the detection surface for each.
A field manual for making a PE invisible to static scanners: entropy, section names, API hashing, string obfuscation, and the compile flags that matter.
Ekko, Foliage, and timer-queue sleep obfuscation compared under the same memory scanner. The writeup is the thesis; the harness is proof.
Writing a minimal PE loader to understand how Windows maps and executes binaries, and where detection can land.
Why indirect syscalls buy less than people think, and what the detection side actually keys on.
No index is complete without the next one.
The dispatch carries one long-form writeup, roughly twice a month. Same standard, same lab, no drip feed.
