The hashcat -I command can be used to see what processing units are available: The GPU operating frequency may be lower (1905 Mhz for boost speed), than the Ryzen’s 4.6 GHz boost speed but the benefits of massively parallel operations wins out. The reason for this performance increase is the GPU contains 2,560 RDNA cores, versus the Ryzen’s 6 processing cores. So, roughly a 1965.35% performance increase. * Device #2: AMD Radeon RX 5700 XT 50th Anniversary, 8064/8176 MB (6949 MB allocatable), 20MCU * Device #1: pthread-AMD Ry6-Core Processor, skipped On the same system, utilising the 5700 XT GPU leads to a significantly faster cracking time:

Hashcat is a password recovery tool which can utilise a computers GPU to significantly speed up the process of finding passwords from their relevant hashed values.

To effectively crack passwords, you need to understand the password policy in place to adjust your approach to cracking accordingly. So, Password1 is a likely candidate 👍 Enumerating the Password Policy This group includes Unicode characters from Asian languages.

Any Unicode character that’s categorized as an alphabetic character but isn’t uppercase or lowercase.

Non-alphanumeric characters (special characters): Currency symbols such as the Euro or British Pound aren’t counted as special characters for this policy setting.

Lowercase letters of European languages (a through z, sharp-s, with diacritic marks, Greek and Cyrillic characters).

Uppercase letters of European languages (A through Z, with diacritic marks, Greek and Cyrillic characters).

As such, it’s important to tailor our password cracking attempts to meet the password requirements imposed by Active Directory.Īs per Microsoft’s documentation by default passwords need to be at least 8 characters long, and contain characters from at least three of the following categories Most organisations use Active Directory for single sign on. These passwords are often required to meet the default Active Directory password policy requirements. During a penetration test, password hashes are often captured using NTLM-SSP interception or by extracting the hashes directly from compromised systems.
