WebApr 10, 2024 · Understanding Kerberoasting attacks and how to prevent them. With the constant headlines of cyberthreats targeting organizations these days, it’s truly hard to keep up. This blog discusses Kerberoasting attacks— a common attack technique where an adversary attempts to crack the password of a service account within Active Directory. A key-recovery attack is an adversary's attempt to recover the cryptographic key of an encryption scheme. Normally this means that the attacker has a pair, or more than one pair, of plaintext message and the corresponding ciphertext. Historically, cryptanalysis of block ciphers has focused on key-recovery, but security against these sorts of attacks is a very weak guarantee since it may not be necessary to recover the key to obtain partial information about the message or decrypt …
