(binary.ninja) AI-Powered Reverse Engineering Exposes Critical Flaws in Encrypted USB Drive Security In brief - This article explores the use of AI-assisted reverse engineering to break the encryption and copy-protection mechanisms of three different USB security products. Technically - This article details the exploitation of cryptographic flaws in NetacFileLock, KakaSoft USB Copy Protection, and Nexcopy. NetacFileLock was found to use a fixed 32-byte AES-256 key embedded in the executable and ECB-style block encryption. KakaSoft utilized a custom modified MD5 hash for key derivation and Blowfish-CBC, but the internal password was derived from an embedded seed, allowing passwordless decryption. Nexcopy employed 3DES-CBC where the content key and IV were stored in an encrypted configuration file, which itself was decrypted using a fixed 32-byte certificate embedded in the viewer application.
