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: WebJan 7, 2024 · if(CryptGetKeyParam( hKey, KP_IV, pbData, &dwCount, 0)) { // Print the initialization vector. _tprintf(TEXT("RE-set IV:")); for(i = 0; i < dwCount; i++) { …
