hashcat:tldr:b140c

This command is invoking the hashcat tool with various parameters to perform a password cracking operation. Here is the breakdown of each component in the command:

• hashcat: This is the executable command for the hashcat tool, a popular password recovery and hash cracking tool.
• --hash-type ${hash_type_id}: This parameter specifies the type of hash algorithm used in the hash you want to crack. The ${hash_type_id} is a variable that should be replaced with the specific hash type identifier.
• --attack-mode ${3}: This parameter defines the attack mode to be used by hashcat. The ${3} is a variable that should be replaced with the desired attack mode identifier. The attack modes can vary, such as brute force, dictionary-based, or combination, among others.
• --increment ${hash_value}: This parameter enables the increment mode, which means that hashcat will generate a progressive password combination starting from the initial value specified by ${hash_value}.
• "${?a?a?a?a?a?a?a?a}": This is the password pattern that hashcat will use during the cracking process. In this example, it is using a pattern of eight lowercase letters. Each ?a represents one character of such pattern. You can modify this pattern to match the expected password structure.

Overall, this command is using hashcat to crack a specific hash of a password by trying various combinations based on the provided attack mode and password pattern.
