计算机网络实用工具之Hydra

简介

Hydra 是一个并行登录破解程序，支持多种协议进行攻击。它非常快速且灵活，并且很容易添加新模块。 该工具使研究人员和安全顾问能够展示远程未经授权访问系统是多么容易。

目前该工具支持以下协议：

 Asterisk, AFP, Cisco AAA, Cisco auth, Cisco enable, CVS, Firebird, FTP,  HTTP-FORM-GET, HTTP-FORM-POST, HTTP-GET, HTTP-HEAD, HTTP-POST, HTTP-PROXY,  HTTPS-FORM-GET, HTTPS-FORM-POST, HTTPS-GET, HTTPS-HEAD, HTTPS-POST,  HTTP-Proxy, ICQ, IMAP, IRC, LDAP, MEMCACHED, MONGODB, MS-SQL, MYSQL, NCP, NNTP, Oracle Listener,  Oracle SID, Oracle, PC-Anywhere, PCNFS, POP3, POSTGRES, Radmin, RDP, Rexec, Rlogin,  Rsh, RTSP, SAP/R3, SIP, SMB, SMTP, SMTP Enum, SNMP v1+v2+v3, SOCKS5,  SSH (v1 and v2), SSHKEY, Subversion, Teamspeak (TS2), Telnet, VMware-Auth,  VNC and XMPP.

※注意：不要用于非法目的，不要用于非授权测试，本文意在说明弱密码的不安全性

# 基于已有的密码字典，按规则过滤并生成新的密码字典

PW-Inspector v0.2 (c) 2005 by van Hauser / THC [e-mail] [https://github.com/vanhauser-thc/thc-hydra]Syntax: pw-inspector [-i FILE] [-o FILE] [-m MINLEN] [-M MAXLEN] [-c MINSETS] -l -u -n -p -sOptions:-i FILE    file to read passwords from (default: stdin)-o FILE    file to write valid passwords to (default: stdout)-m MINLEN  minimum length of a valid password-M MAXLEN  maximum length of a valid password-c MINSETS the minimum number of sets required (default: all given)
Sets:-l         lowcase characters (a,b,c,d, etc.)-u         upcase characters (A,B,C,D, etc.)-n         numbers (1,2,3,4, etc.)-p         printable characters (which are not -l/-n/-p, e.g. $,!,/,(,*, etc.)-s         special characters - all others not withint the sets abovePW-Inspector reads passwords in and prints those which meet the requirements.
The return code is the number of valid passwords found, 0 if none was found.
Use for security: check passwords, if 0 is returned, reject password choice.
Use for hacking: trim your dictionary file to the pw requirements of the target.
Usage only allowed for legal purposes.

使用示例

从已有密码字典生成新密码字典

# 从已有密码字典中过滤出长度为5-7位的密码
root@ubuntu:~# pw-inspector -i ./passwd.list -o ./new_passwd.list -m 5 -M 7# 原密码文件
root@ubuntu:~# cat passwd.list 
1234
12345
123456
1234567
12345678
123456789# 新密码文件
root@ubuntu:~# cat new_passwd.list 
12345
123456
1234567
