007
Correlates DNS TXT-tunneling activity and HTTP POST traffic from the same host resolving to the same base destination domain within a 2-minute window, with minimum volume thresholds on each channel, consistent with malware that branches between DNS tunneling and HTTP POST C2 modes based on the first byte of a decrypted configuration string.

Detects the Abyssos RAT main executable via known sample hashes, or by requiring a minimum weight/threshold of co-occurring structural PE traits (obfuscated single-executable-section layout, minimal static import table consistent with CRC32-based dynamic API hashing, and absence of a valid certificate), rather than any single trait alone.
