7MS #261: Blind Network Security Assessments

This week I had the fun opportunity to do a "blind" network security assessment - where basically we had to step into a network we'd never seen before and make some security posture recommendations. I've found that the following software/hardware is quite helpful for this type of assessment:

  • The PwnPulse helps a ton in scanning wired and wireless networks...and even Bluetooth! I've covered the Pulse in past episodes - check out part 1 and part 2.

  • Network Detective will do a ton of helpful Active Directory enumeration and point out potential red flags, such as:

    • Accounts that haven't been logged into for a long time
    • Accounts with passwords that haven't been refreshed in a long time
    • Privileged groups that need review (Domain Admins, Enterprise Admins, etc.)
  • AD policy issues (*warning: by default Network Detective only pulls back a few policies by default. Check out scripts such as my Environment Check to grab a dump of all GPOs.

  • Thycotic Privileged Account Discovery is a free tool that can crawl AD workstations and enumerate the local administrator accounts on each machine. It makes a good case for implementing LAPS.

Every once in a while I thought it would be fun to go slightly off topic and talk about other stuff I’m interested in. This episode kind of has a tech twist though. I talk about how I use my iPhone and a few apps to stay at least a little bit in shape. 7MS…

I found a great bit of reading that walks you through the “plays” of hacking – enumeration, exploitation, post-exploitation, etc. It’s a great (and affordable) book called The Hacker Playbook. Cheggitowt! Download: 7MS #34: The Hacker Playbook (audio)

Network Detective is a tool we’ve been using as kind of an addendum to our full security assessment. It gives some nice, plain-English Excel spreadsheets and Word docs that report on AD health and structure, PC inventory and open ports, AV clients that aren’t working right, and a whole lot more.
