K30215094: Ruby vulnerability CVE-2016-7798

Security Advisory Description The openssl gem for Ruby uses the same initialization vector IV in GCM Mode aes--gcm when the IV is set before the key, which makes it easier for context-dependent attackers to bypass the encryption protection mechanism. CVE-2016-7798 Impact There is no impact; F5...

EXOCET - AV-evading, Undetectable, Payload Delivery Tool

EXOCET is superior to Metasploit's "Evasive Payloads" modules as EXOCET uses AES-256 in GCM Mode Galois/Counter Mode. Metasploit's Evasion Payloads uses a easy to detect RC4 encryption. While RC4 can decrypt faster, AES-256 is much more difficult to ascertain the intent of the malware. However, i...
