7MS #420: Tales of Internal Pentest Pwnage - Part 17 Jun 26, 2020

Show notes

Today's episode is a fun tale of pentest pwnage! Interestingly, to me this pentest had a ton of time-sponging issues on the front end, but the TTDA (Time to Domain Admin) was maybe my fastest ever.

I had to actually roll a fresh Kali VM to upload to the customer site, and I learned (the hard way) to make that VM disk as lean as possible. I got away with a 15 gig drive, and the OS+tools+updates took up about 12 gig.

One of the biggest lessons I learned from this experience is to make sure that not only is your Kali box updated before you take it to a customer site (see this script), but you should make sure you install all the tool dependencies beforehand as well (specifically, Eyewitness, Impacket and MITM6).

This pentest was also extremely time-boxed, so I tried to get as much bang out of it as possible. This included:

Capturing hashes with Responder
Checking for "Kerberoastable" accounts (GetUserSPNs.py -request -dc-ip x.x.x.x domain/user)
Check for MS14-025 (see this article)
Check for MS17-010 (nmap -Pn -p445 --open --max-hostgroup 3 --script smb-vuln-ms17-010 192.168.0.0/24 -oA vulnerable-2-eblue) and try this method of exploiting it
Check for DNS zone transfer (dnsrecon -d name.of.fqdn -t axf)
Test for egress filtering of ports 1-1024
Took a backup of AD "the Microsoft way" and then cracked with secretsdump:

sudo python ./secretsdump.py -ntds /loot/Active\ Directory/ntds.dit -system /loot/registry/SYSTEM -hashes lmhash:nthash LOCAL -outputfile /loot/ad-pw-dump

7MS #419: Eating the Security Dog Food Jun 17, 2020

Show notes

Today we're talking about eating the security dog food! What do I mean by that? Well, a lot of security companies I worked for in the past preached to clients about the importance of having a good security program, but didn't have one of their own! I'm trying to break that pattern now that I'm in a position to lead an information security program for 7MS.

In today's episode we talk about getting your company started with a good set of infosec policies/procedures. First up is a "mothership" infosec policy with the following sub-policies inside it:

Acceptable Use
Data Protection and Privacy
Physical Security
Tools and Technology
Training and Awareness
Reporting

Oh, and the song I jazz/scat/sang coming out of the jingle was If I Were a Dog

7MS #417: Vulnerability Scanning Tips and Tricks Jun 04, 2020

Show notes

Today's episode is all about getting the most value out of your vulnerability scans, including:

Why, IMHO you should only do credentialed scans
Policy tweaks that will keep servers from tipping over and printers from printing novels of gibberish ;-)
How to make your scan report more actionable and less unruly
Turning up logging to 11 (use with caution!)
A small tweak to an external scan policy that can result in the difference between a successful or failed scan
The nessusd.rules file is awesome for excluding specific hosts and services from your scans

7MS #416: Pi-hole 5.0 May 28, 2020

Show notes

This podcast is sponsored by Arctic Wolf, whose Concierge Security teams Monitor, Detect and Respond to Cyber threats 24/7 for thousands of customers around the world. Arctic Wolf. Redefining cybersecurity. Visit Arcticwolf.com/7MS to learn more.

Today we're talking about some of my favorite features of Pi-hole 5.0. Including:

WARNING! WARNING! Upgrading from 4.x is a one-way operation!
Per-client blocking (you can setup, for example, a group machines called "kids" and apply specific domain block/allow lists and domains to them)
More granular detail (especially if there are issues) when blocklists get updated
Better, richer debug log output

I also talk about a great companion for yor Pi-hole: a command-line Internet speed test! Hat tip to Javali over at the 7MS forums who told me about this.

Additionally, I briefly mention "Hashy" (the nickname of my password cracking rig), give you some stay-at-home streaming TV show recommendations, and give you a quick house rebuild update!

7MS #413: PCI Professional Certification (PCIP) - Part 3 May 07, 2020

Show notes

Hey everybody! I hope you're hanging in there during quarantine and staying healthy. Today is part 3 of our ongoing series all about becoming a PCIP. The good news is I'm finally, actually registered for the cert and have started diving into the training! So in today's episode I want to regurgitate some of what I'm learning to whet your appetite (or not) for this particular certification. Specifically, we cover:

The overview and objectives for being a PCIP (TLDR: PCIP does NOT replace QSA or ISA, but gives us a good understanding of how to protect payment card data)
How and why payment card data is leaked/stolen/breached - and then sold/monetized
The definition of some fundamental PCI acronym soup, including PCI DSS, PA-DSS and P2PE
