MITRE ATT&CK Enterprise TechniquesAI

T1110.002 Password Cracking Credential Access
Adversaries may use password cracking to attempt to recover usable credentials, such as plaintext passwords, when credential material such as password hashes are obtained.
Why these techniques?

Explicit mention of weak hashing limiting password length and enabling brute force directly maps to password cracking technique.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires organizations to manage authenticators using approved cryptographic methods that resist brute-force attacks, addressing the weak password hashing in the VDR.

prevent

Mandates cryptographic protection of information at rest, directly mitigating exposure of password hashes stored with insufficient strength.

prevent

Requires use of approved cryptographic algorithms and key lengths, which would preclude the weak hashing algorithm described in the CVE.
