Cryptsetkeyparam iv

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: WebC++ (Cpp) CryptSetKeyParam - 23 examples found.
