A Mole Infiltrated the Highest Ranks of American Militias. This Is What He Found. Outraged by the Jan. 6 Capitol riot, a wilderness survival trainer spent years undercover climbing the ranks of right-wing militias. He didn’t tell police or the FBI. He didn’t tell family or friends....

He penetrated the top ranks of prominent right-wing militias & devised elaborate ruses to gather evidence of ties to high-ranking law enforcement officials.

He was so successful, he became a militia’s top commander in Utah.

Commandments of a good file format: Magic at offset zero. Fast identification, no bypass Up-to-date specs Reflect reality Clear chunk structure forward compatibility, easy parsing/cleanup Samples set Theory isn't enough Version number Forward thinking Extensibility Your format will evolve in unknown ways No duplicity Duplicity -> discrepency (skull emoji) Keep the spirit Don't reuse formats for different intent without trivial distinction No "constant" variables Ossification -> hardcoding Perfect is the enemy of good Shortcuts will be taken to avoid over-complexity

In your forward engineering career if you ever have the chance to design a new file format, please listen to the advice from Ange Albertini's 2024 38C3 talk

Cognitive load is what matters There are so many buzzwords and best practices out there, but let's focus on something more fundamental. What matters is the amount of confusion developers feel when going through the code.

Cognitive load is what we fight with in reverse engineering too. Obfuscation is cognitive load

Reverse engineers try to find patterns to reduce load
Forward engineers try to reduce complexity

Sean is damn right: C++ structs are tricky. Decompilers universally work better once you fill out structs and types.
