WebOct 31, 2024 · The relatively simplistic form of password hashing makes NTLM systems vulnerable to several modes of attacks, including pass-the-hash and brute-force attacks. Outdated cryptography. NTLM does not leverage the latest advances in algorithmic thinking or encryption to make passwords more secure. WebIn CBC mode, you encrypt a block of data by taking the current plaintext block and exclusive-oring that wth the previous ciphertext block (or IV), and then sending the result of that through the block cipher; the output of the block cipher is the ciphertext block. GCM mode provides both privacy (encryption) and integrity.
