T1110.002 Password Cracking
Sub-technique of: T1110
High-Level Description
Adversaries may use password cracking to attempt to recover usable credentials, such as plaintext passwords, when credential material such as password hashes are obtained. OS Credential Dumping can be used to obtain password hashes, this may only get an adversary so far when Pass the Hash is not an option. Further, adversaries may leverage Data from Configuration Repository in order to obtain hashed credentials for network devices.
Techniques to systematically guess the passwords used to compute hashes are available, or the adversary may use a pre-computed rainbow table to crack hashes. Cracking hashes is usually done on adversary-controlled systems outside of the target network. The resulting plaintext password resulting from a successfully cracked hash may be used to log into systems, resources, and services in which the account has access.

What to Check
How to Test
Atomic Red Team Tests
The following tests are from Atomic Red Team and provide actionable ways to test this technique:
Atomic Test 1: Password Cracking with Hashcat
Execute Hashcat.exe with provided SAM file from registry of Windows and Password list to crack against
Supported Platforms: windows
Elevation Required: Yes
cd #{hashcat_exe}\..
#{hashcat_exe} -a 0 -m 1000 -r .\rules\Incisive-leetspeak.rule #{input_file_sam} #{input_file_passwords}
Dependencies:
- Hashcat must exist on disk at specified location (#{hashcat_exe})
