7MS #364: Tales of External Pentest Pwnage

This episode of the 7 Minute Security Podcast is brought to you by Authentic8, creators of Silo. Silo allows its users to conduct online investigations to collect information off the web securely and anonymously. For more information, check out Authentic8.

This episode features cool things I'm learning about external pentesting. But first, some updates:

  • My talk at Secure360 went really well. Only slightly #awkward thing is I felt an overwhelming need to change my title slide to talk about the fact that I don't drink.

  • The 7MS User Group went well. We'll resume in the late summer or early fall and do a session on lockpicking!

  • Wednesday night my band had the honor of singing at a Minnesota LEMA service and wow, what an honor. To see the sea of officers and their supportive families and loved ones was incredibly powerful.

On the external pentest front, here are some items we cover in today's show:

  • MailSniper's Invoke-DomainHarvestOWA helps you discover the FQDN of your mail server target. Invoke-UsernameHarvestOWA helps you figure out what username scheme your target is using. Invoke-PasswordSprayOWA helps you do a low and slow password spray to hopefully find some creds!

  • Once inside the network, CrackMapExec is your friend. You can figure out where your compromised creds are valid across the network with this syntax:

crackmapexec smb 192.168.0.0/24 -u USER -p ‘PASSWORD’ -d YOURDOMAIN

You can also find what shares you have access to with:

crackmapexec smb 192.168.0.0/24 -u USER -p ‘PASSWORD’ -d YOURDOMAIN --shares

Sift through those shares! They often have VERY delicious bits of information in them :-)

7MS #58: What Should We Do First? (audio)

At the end of just about every assessment I deliver, the client asks “What should we do first?” They (understandably) want to know a “top 5″ list of things they should change right away to improve their security posture. Today’s episode explores that a bit. 7MS #58: What Should We Do Next? (audio)

7MS #54: Traveling with a Red Giant (audio)

If you’re concerned about your credit/debit card security, you might want to give Red Giant a try. It’s a service that provides a debit card you can unlock *only* when buying something. It’s cool. Oh, and Red Giant is NOT sponsoring this episode. If I ever get sponsors, I’ll disclose them clearly. :-) 7MS #54:…

Business DR plans are a hugely important – and often overlooked – piece of the infosec puzzle. But what about at home? If you got run over by a bus tomorrow, would you have good plans in place to help your partner/spouse take over the tech side of your household? That’s what we’re talkin’ about…
