7MS #464: Interview with Christopher Fielder of Arctic Wolf

Hey friends, today we have a super fun interview with Andrew Morris of GreyNoise to share.  Andrew chatted with us about: Young Andrew’s early adventures in hacking his school’s infrastructure (note: don’t try this at home, kids!) Meeting a pentester for the first time, and getting his first pentesting job Spinning up a box on the internet, having it get popped instantly, and wondering…”Are all these people trying to hack me?” Battling through a pentester’s least favorite part of the job: THE REPORT! GreyNoise’s origin story How to build a better honeypot/honeynet

Hey friends, sorry I’m so late with this (er, last) week’s episode but I’m back!  Today is more of a prep for tales of pentest pwnage, but topics covered include: Make sure when you’re snafflin‘ that you check for encrypted/obfuscated logins and login strings – it might not be too tough to decrypt them! On the defensive side, I’ve found myself getting *blocked* doing things like SharpHound runs, Snaffler, PowerHuntShares, etc.  Look through the readme files for these tools and try cranking down the intensity/threads of these tools and you might fly under the radar.

Today’s tale of pentest covers: Farming for credentials (don’t forget to understand trusted zones to make this happen properly!) Snaffling for juice file shares Stealing Kerberos tickets with Rubeus

Hello friends, we’re still deep in the podcast trenches this quarter and wanted to share some nuggets of cool stuff we’ve been learning along the way: Snaffler – pairs nicely with PowerHuntShares to find juicy tidbits within file/folder shares Group3r – helps you find interesting and potentially abusable Group Policy Object configurations Farmer – totally awesome toolkit for dropping tricky files on shares that will do things like fire up the Webclient service for any system browsing the share (doesn’t require admin rights!) or coaxing a system into authenticating with you via HTTP or SMB

Hey friends, sorry for the late episode but I've been deep in the trenches of pentest adventures.  I'll do a more formal tale of pentest pwnage when I come up for air, but for now I wanted to share some tips I've picked up from recent engagements: GraphRunner - awesome PowerShell toolkit for interacting with Microsoft Graph API.  From a pentesting perspective, it may help you bridge the "gap" between LAN-side AD and Azure and find some goodies - like files with and XSLX extension containing the word password. PowerUpSQL -I typically use this to make SQL servers cough me up a hash via SMB using stored procedures, but I learned this week that I'll deeeefffffinitely use the Invoke-SQLAudit -Verbose functionality going forward.

Hey friends, today we cover a funstrating (that's fun + frustrating) issue we had with our DIY pentest dropboxes. TLDL:   The preseed file got jacked because I had a bad Kali metapackage in it. While I was tinkering around with preseed files, I decided it would be more efficient to have the Kali ISO call that preseed file directly over HTTP (rather than make a new ISO every time I made a preseed change).  To accomplish that: Mount the Kali ISO Explore to isolinux > txt.cfg Modify the txt.cfg to include a custom boot option that calls your preseed over HTTP.  For example: label install menu label ^Install Yermaum kernel /install.amd/vmlinuz append net.ifnames=0 preseed/url=https://somewebsite/kali.preseed locale=en_US keymap=us hostname=kali777 domain=7min.sec simple-cdd/profiles=kali desktop=xfce vga=788 initrd=/install.amd/initrd.gz --- quiet

Hey friends, today is a first impressions episode about Sysreptor, which according to their GitHub page, is a fully customisable, offensive security reporting solution designed for pentesters, red teamers and other security-related people alike.  It is easy to stand up with Docker, has built-in MFA and a great hybrid WYSIWYG/code editor.  The only scary part?  There is no export to Word (insert suspenseful music here!) - your reports just go right to PDF, friends!  The killer feature for us, though, is the ability to create reports from the command line and send files, notes and findings to Sysreptor automagically!
