tl;dr

i spent a day analyzing enigma protector - a $200 commercial software protection system used by thousands of vendors. RSA cryptographic signatures, hardware-bound licensing, anti-debugging, VM-based code obfuscation. serious enterprise security theater.

xcopy /E "C:\Program Files\...\product" . \c rack \

that’s the entire crack. copy the installed files. they run on any machine. no keygen needed, no binary patching, no cryptanalysis.

$200 protection defeated by a command that shipped with DOS 3.2 in 1986.

this is a case study in why threat modeling matters more than fancy cryptography, and why “military-grade encryption” means nothing when you leave the back door wide open.
