关于密码破解-密码破解的方式
l
Dictionary 字典
l
Rainbow Table 彩虹表
l
Brute Force 暴力枚举
l
Hybrid 混合式攻击
l
Commonly Used Passwords 常用密码
关于密码破解-kali中的密码破解工具
关于密码破解-硬件
l
Botnet僵尸网络
l
GPU 显卡
l
ASIC专用集成电路
关于密码破解-密码破解基本策略
l
1.识别加密类型
l
2.对较短的密码直接实施暴力破解
l
3.尝试常用密码
l
4.组合常用密码/单词/拼音与数字
l
5.混合暴力攻击
l
6.如果还失败了。。Gpu，僵尸网络，集成电路，分布式
l
7.不行就算了，一个密码而已
工具使用示例-hashcat
l
启动 hashcat
l
查看帮助 hashcat –help
l
character sets
l
Hashtype
l
关于掩码和参数，参考：http://xiao106347.blog.163.com/blog/static/215992078201451082547241/
l
http://drops.wooyun.org/tools/655
l Kali内置的字典文件 locate wordlist
l 获取linux系统的密码hash
/etc/shadow
l 获取加密类型 /etc/login.defs
l 破解hash
hashcat -m 1800 -a 0 -o cracked.txt hash.lst /usr/share/sqlmap/txt/wordlist.txt
l 掩码攻击
l 准备测试md5值
l 进行攻击
l Hashcat的gpu版本oclhashcat
l http://hashcat.net/oclhashcat/
工具使用示例—crunch
l
字典生成
l
crunch <min> max<max>
<characterset> -t <pattern> -o <output filename>
l
crunch 4 8
l
crunch 6 8 1234567890 -o
/root/numericwordlist.lst
l
crunch 10 10 -t @@@@@@0728 -o
/root/birthdaywordlist.lst
l
crunch 8 8 -f
/usr/share/rainbowcrack/charset.txt mixalpha -o /root/alphawordlist.lst
工具使用示例-onlinecrack
l
1.burpsuit 参考之前的课程
l
2.hydra
l
-R
继续从上一次进度接着破解
l
-S
大写，采用SSL链接
l
-s <PORT>
小写，可通过这个参数指定非默认端口
l
-l <LOGIN>
指定破解的用户，对特定用户破解
l
-L <FILE>
指定用户名字典
l
-p <PASS>
小写，指定密码破解，少用，一般是采用密码字典
l
-P <FILE>
大写，指定密码字典
l
-e <ns>
可选选项，n：空密码试探，s：使用指定用户和密码试探
l
-C <FILE>
使用冒号分割格式，例如“登录名:密码”来代替-L/-P参数
l
-M <FILE>
指定目标列表文件一行一条
l
-o <FILE>
指定结果输出文件
l
-f
在使用-M参数以后，找到第一对登录名或者密码的时候中止破解
l
-t <TASKS>
同时运行的线程数，默认为16
l
-w <TIME>
设置最大超时的时间，单位秒，默认是30s
l
-v / -V
显示详细过程
l
server
目标ip
l
service
指定服务名，支持的服务和协议：telnet
ftp pop3[-ntlm] imap[-ntlm] smb smbnt http[s]-{head|get} http-{get|post}-form
http-proxy cisco cisco-enable vnc ldap2 ldap3 mssql mysql oracle-listener
postgres nntp socks5 rexec rlogin pcnfs snmp rsh cvs svn icq sapr3 ssh2
smtp-auth[-ntlm] pcanywhere teamspeak sip vmauthd firebird ncp afp等等
l
OPT
可选项
l
Ssh破解：hydra -L users.txt -P password.txt -t 1 -vV -e ns 127.0.0.1 ssh
l
ftp破解：hydra ip ftp -l 用户名 -P 密码字典 -t
线程(默认16) -vV
hydra ip
ftp -l 用户名 -P 密码字典 -e ns -vV
