The winter solstice is our annual reminder that just when it seems the darkness is too much, the light will return. Regardless of season, may your hearts forever stay warm. ♥️

This was a lot of work to get here. Special shoutout to @HackingLZ for doing the brunt of the work (it wasn't easy) and for the amazing folks at @OpenAI - they are awesome to work with. Huge moment for us to continue to expand our capabilities, and this new field that is being formed and rapidly moving ever single day. #TrustedSec
TrustedSec has joined the @OpenAI Daybreak Defense Network! Planned use of #Daybreak Blue and Red will integrate OpenAI GPT cyber models into our offensive and defensive security services, pairing it with the experience and judgment of our consultants. Announcement below 👇

APTBigDaddy's opening his red teamer's book of tales, so you can hack a water tower, too. justhacking.com/hackalong/ha… Hack-Along with @DahvidSchloss in a dedicated virtual lab. Or 3D Print your own! JHT’s resident Windows Malware Dev guru occasionally leaves Windows alone long enough to cause problems for industrial control systems (ICS). From his past experiences in physical red teaming and government “green-door” programs, he’s spent real time finding out how to turn a computer problem into an everyone problem. Naturally, in his own way, his idea to teach you all about this danger was: “We should let students hack a water tower.” Apparently, this counts as curriculum. In this Hack-Along (HAL), the focus is on Modbus, which Dahvid calls the gateway drug to paranoid anxiety about the future of the universe. Dahvid is also one of the main members of The Cyber Idiots, a group of like-minded individuals who have a passion for cybersecurity and believe that education should be entertaining. They produce research and sometimes post videos and blogs on a variety of subjects related to cybersecurity including offensive security, threat hunting, tool use, and cybersecurity news. This is their latest fun way to learn. We think you’ll agree! #ethicalhacking #hacker #maker #ics #iot

How to own a domain controller in 4 commands 🎫 (in a lab, obviously 🫡) Dump a CIFS ticket with Rubeus Save it as a .kirbi file Pass-the-ticket back with Rubeus dir \\DC\C$ → you're in Kerberos abuse is one of those things that sounds terrifying until you see it.
