1## Cybersecurity Skills (Invoke First)
2 
3Before starting any password attack task, invoke these skills via the Skill tool:
4- `cybersecurity-skills:performing-hash-cracking-with-hashcat`
5- `cybersecurity-skills:hunting-credential-stuffing-attacks`
6- `cybersecurity-skills:performing-privilege-escalation-on-linux`
7 
8## Scope Enforcement
9 
10Before cracking any hash, verify the source system is in scope:
11 
12```bash
13# Confirm the target that produced the hash is listed in scope.txt
14grep -v '^#' scope.txt | grep -v '^$'
15 
16# Document where hashes came from
17echo "Hash source: $SOURCE_HOST — confirmed in scope.txt before proceeding"
18```
19 
20**NEVER crack hashes from systems not listed in scope.txt.**
21**NEVER store recovered plaintext passwords — reference hash type, crack time, and pattern only.**
22 
23## Hash Identification
24 
25Always identify the hash type before selecting a mode:
26 
27```bash
28# hashid — broad coverage, suggests hashcat mode
29hashid '$hash_value'
30hashid -m '$hash_value'
31 
32# haiti — more precise, handles edge cases
33haiti '$hash_value'
34 
35# hashcat --identify (newer versions)
36hashcat --identify hashes.txt
37 
38# Manual identification by format:
39# NTLM: 32 hex chars, no prefix e.g. aad3b435b51404eeaad3b435b51404ee
40# NetNTLMv2: user::domain:challenge:response (contains :: and multiple colons)
41# Kerberoast: $krb5tgs$23$*...$ (starts with $krb5tgs$)
42# ASREP: $krb5asrep$23$... (starts with $krb5asrep$)
43# bcrypt: $2a$ or $2b$ or $2y$ (60 chars total)
44# sha512crypt: $6$... (starts with $6$)
45# MD5crypt: $1$... (starts with $1$)
46# JWT: eyJ...eyJ...signature (three base64url segments)
47```

75## Attack Modes
76 
77### -a 0 — Dictionary Attack (always start here)
78 
79```bash
80# Basic dictionary — first pass
81hashcat -m $MODE \
82 evidence/$(date +%Y%m%d)/$TARGET/hashes.txt \
83 /usr/share/wordlists/rockyou.txt \
84 -o evidence/$(date +%Y%m%d)/$TARGET/cracked.txt \
85 --outfmt 2 \
86 -w 3
87 
88# Dictionary + best64 rule (fast, good coverage)
89hashcat -m $MODE \
90 evidence/$(date +%Y%m%d)/$TARGET/hashes.txt \
91 /usr/share/wordlists/rockyou.txt \
92 -r /usr/share/hashcat/rules/best64.rule \
93 -o evidence/$(date +%Y%m%d)/$TARGET/cracked.txt \
94 --outfmt 2 -w 3
95 
96# Dictionary + d3ad0ne rule (broader, slower)
97hashcat -m $MODE \
98 evidence/$(date +%Y%m%d)/$TARGET/hashes.txt \
99 /usr/share/wordlists/rockyou.txt \
100 -r /usr/share/hashcat/rules/d3ad0ne.rule \

102 --outfmt 2
103 
104# Dictionary + OneRuleToRuleThemAll
105# Download: https://github.com/NotSoSecure/password_cracking_rules
106hashcat -m $MODE \
107 evidence/$(date +%Y%m%d)/$TARGET/hashes.txt \
108 /usr/share/wordlists/rockyou.txt \
109 -r /opt/OneRuleToRuleThemAll.rule \
110 -o evidence/$(date +%Y%m%d)/$TARGET/cracked.txt \
111 --outfmt 2
112 
113# Stacked rules (sequential — apply both transforms)
114hashcat -m $MODE \
115 evidence/$(date +%Y%m%d)/$TARGET/hashes.txt \
116 /usr/share/wordlists/rockyou.txt \
117 -r /usr/share/hashcat/rules/best64.rule \

119 -o evidence/$(date +%Y%m%d)/$TARGET/cracked.txt \
120 --outfmt 2
121```
122 
123### -a 1 — Combinator Attack
124 
125```bash
126# Pairs every word in list1 with every word in list2
127hashcat -m $MODE \
128 evidence/$(date +%Y%m%d)/$TARGET/hashes.txt \
129 -a 1 \
130 /usr/share/seclists/Passwords/Common-Credentials/500-worst-passwords.txt \
