# Hashcat

> World's fastest and most advanced password recovery utility\
> [GitHub - hashcat/hashcat](https://github.com/hashcat/hashcat)

## Basic usage

Find hash-type (for `-m` option)\
`hashcat --example-hashes` or [example\_hashes](https://hashcat.net/wiki/doku.php?id=example_hashes)\
-> search for start of hash (e.g. `$7z`)

Execute hashcat

```bash
hashcat -m 5600 <hashes-file> <wordlist-file>
```

## Wordlist attacks

Using rule to increase coverage, e.g. [OneRuleToRuleThemAll.rule](https://github.com/NotSoSecure/password_cracking_rules)

```bash
hashcat -m 1000 hashes.txt rockyou.txt -r OneRuleToRuleThemAll.rule
```

NTLM

```bash
hashcat -m 1000 'abd3b436b51404eeaad3c435b51404ee:b84242f37e45371aff235a6ebcac4ffe' rockyou.txt
```

mscash

```bash
hashcat -m 2100 '$DCC2$10240#administrator#65481e9a192e14343eb382574678c93c' rockyou.txt
```

## Brute force (mask) attacks

Built-in charsets

```
?l = abcdefghijklmnopqrstuvwxyz
?u = ABCDEFGHIJKLMNOPQRSTUVWXYZ
?d = 0123456789
?h = 0123456789abcdef
?H = 0123456789ABCDEF
?s = «space»!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~ 
?a = ?l?u?d?s
?b = 0x00 - 0xff
```

Example #1

```bash
hashcat -a 3 -m 1000 hashes.txt -1 2?l?d2 "?1?1?1?1?1?1?1"
```

Example #2

```bash
hashcat -a 3 -m 1000 hashes.txt --increment -1 "?l?u" -2 "?s?d" "?1?l?l?l?l?l?2?2"
```
