About hashcat-crack

A hashcat offline password-hashing skill for security testers. It outlines hash identification, attack-mode selection, and workflows using dictionaries, rules, masks, and combinations across common hash types.

Key features

  1. 01Identify common hash types
  2. 02Run dictionary and rule attacks
  3. 03Build mask and combination attacks
  4. 04Handle Kerberos and NTLM hashes
  5. 05View results and restore jobs

Use cases

  1. 01Test leaked NTLM hashes
  2. 02Assess Kerberoast or AS-REP hashes
  3. 03Build masks from known password patterns
  4. 04Resume interrupted cracking jobs

Install

Copy the command and run it in a terminal.

$npx skills add https://github.com/wgpsec/aboutsecurity --skill hashcat-crack

After installing, type/hashcat-crackin Claude Code to confirm it loaded.

hashcat 密码哈希离线破解

hashcat 利用 GPU 加速哈希破解,速度远超 CPU。核心工作流:识别哈希类型 → 选择攻击模式 → 喂字典/规则/掩码。

哈希类型识别(-m 参数)

哈希类型-m 值来源
NTLM1000hashdump / secretsdump
NetNTLMv15500Responder 抓包(旧系统/降级攻击)
NetNTLMv25600Responder / ntlmrelayx 抓包
Kerberos TGS (Kerberoast)13100GetUserSPNs.py
Kerberos AS-REP18200GetNPUsers.py
MD50Web 数据库泄露
SHA-2561400—
Raw SHA-5121700128 字符十六进制摘要
sha512crypt ($6$)1800Linux /etc/shadow
bcrypt3200Web 应用
DCC2 (Domain Cached Credentials 2)2100secretsdump 域缓存凭据
WPA-PBKDF222000WiFi 握手包

攻击模式

字典攻击(最常用)
# 基本字典攻击
hashcat -m 1000 hashes.txt /usr/share/wordlists/rockyou.txt

# 加规则(变形字典,如 password → Password1!)
hashcat -m 1000 hashes.txt /usr/share/wordlists/rockyou.txt -r /usr/share/hashcat/rules/best64.rule

# 常用规则文件
# best64.rule — 64 条高效规则,速度和效果平衡
# rockyou-30000.rule — 大规则集,覆盖更多变形
# OneRuleToRuleThemAll.rule — 社区最强规则集
掩码攻击(已知密码模式)
# 8 位纯数字
hashcat -m 1000 hashes.txt -a 3 ?d?d?d?d?d?d?d?d

# 首字母大写 + 6 位小写 + 1 位数字(如 Password1)
hashcat -m 1000 hashes.txt -a 3 ?u?l?l?l?l?l?l?d

# 掩码字符集:?l=小写 ?u=大写 ?d=数字 ?s=特殊 ?a=全部
组合攻击
# 两个字典组合(word1+word2)
hashcat -m 1000 hashes.txt -a 1 dict1.txt dict2.txt

实战场景

Kerberoast 破解
# GetUserSPNs.py 输出 → hashcat
GetUserSPNs.py domain/user:pass -dc-ip DC_IP -request -outputfile tgs.txt
hashcat -m 13100 tgs.txt /usr/share/wordlists/rockyou.txt -r /usr/share/hashcat/rules/best64.rule
AS-REP Roasting 破解
GetNPUsers.py domain/ -usersfile users.txt -no-pass -dc-ip DC_IP -outputfile asrep.txt
hashcat -m 18200 asrep.txt /usr/share/wordlists/rockyou.txt
NTLM 哈希破解(hashdump/secretsdump)
# secretsdump 输出格式:user:RID:LM:NTLM:::
# 提取 NTLM 部分
cat secretsdump.txt | awk -F: '{print $4}' | sort -u > ntlm.txt
hashcat -m 1000 ntlm.txt /usr/share/wordlists/rockyou.txt -r /usr/share/hashcat/rules/best64.rule
NetNTLMv2 破解(Responder 抓取)
hashcat -m 5600 responder_hashes.txt /usr/share/wordlists/rockyou.txt

实用参数

# 查看已破解结果
hashcat -m 1000 hashes.txt --show

# 继续中断的任务
hashcat -m 1000 hashes.txt --restore

# 只跑 GPU(不用 CPU)
hashcat -m 1000 hashes.txt -D 2

# 设置工作负载(1=低 2=默认 3=高 4=极限)
hashcat -m 1000 hashes.txt -w 3

# 内核优化(截断密码长度换速度,多数场景够用)
hashcat -m 1000 hashes.txt -O

# 输出到文件
hashcat -m 1000 hashes.txt wordlist.txt -o cracked.txt

决策树

拿到哈希后:
├─ 知道哈希类型 → 直接 hashcat -m 值
├─ 不确定类型 → hashcat --identify hashes.txt 或 hashid
├─ 有 GPU → hashcat(首选)
├─ 无 GPU / CPU 环境 → john the ripper
└─ 在线查询 → hashes.org / crackstation.net(先试再跑)
