WebSep 12, 2015 · Use any IV on decrypt and throw away that first block (because it will be garbage). It's all pretty much the same result (you end up transmitting 16 bytes as overhead), but you should put some randomness into your message (either through the IV or the first block) to thwart short cut attacks. Share Improve this answer Follow WebThis RAT uses CryptoAPI to generate a random key, encrypting the data it sends to the C2 with RC4. First, the malware calls CryptGenRandom to fill a 6-byte buffer with random data. After this, it concatenates the strings ‘OrcaKiller’ to this random buffer and calculates MD5 using CryptoAPI too. It derives the RC4 from this MD5 value: chiropodists coventry
