Asleap包装说明
演示专有思科LEAP网络的一个严重缺陷。由于LEAP使用MS-CHAPv2的一个变体的身份验证交换,很容易加速离线字典攻击。 Asleap也可以攻击点点对点隧道协议(PPTP),以及任何MS-CHAPv2的交流,你可以在命令行上指定的挑战和响应值。 资料来源:http://www.willhackforsushi.com/?page_id=41

asleap - 积极恢复LEAP / PPTP密码:~# asleap -h asleap 2.2 - actively recover LEAP/PPTP passwords. < > Usage: asleap [options] -r Read from a libpcap file -i Interface to capture on -f Dictionary file with NT hashes -n Index file for NT hashes -s Skip the check to make sure authentication was successful -h Output this help information and exit -v Print verbose information (more -v for more verbosity) -V Print program version and exit -C Challenge value in colon-delimited bytes -R Response value in colon-delimited bytes -W ASCII dictionary file (special purpose)
0x02 genkeys - 生成asleap查找文件
:~# genkeys genkeys 2.2 - generates lookup file for asleap. < > genkeys: Must supply -r -f and -n Usage: genkeys [options] -r Input dictionary file, one word per line -f Output pass+hash filename -n Output index filename -h Last 2 hash bytes to filter with (optional)
0x03 genkeys用法示例
读在一个词典 文件* - (-r /usr/share/wordlists/nmap.lst), 提供输出文件名 (-f asleap.dat), 和一个输出索引文件名 (-n asleap.idx):
:~# genkeys -r /usr/share/wordlists/nmap.lst -f asleap.dat -n asleap.idx
genkeys 2.2 - generates lookup file for asleap. <
