7 Minute Security

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

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

Today's episode is all about mental health! I talk about some of my challenges with stress/anxiety and how I finally put on my big boy pants, dropped some misconceptions and decided to do something about it. Additionally, this episode contains references to:

• Jon Secada
• Arsenio Hall
• Lone Wolf McQuade

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

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!
