A little month than month ago i finished the wargames challanges by RET2 Systems. Before this course i had 0 knowledge regarding low-level exploitation techniques, mitigations and bypass strategies. The course really pushes you and gives you knowledge required to break into VR💯

On the passing of our dear friend and alumni, Sophia "quend" d'Antoine (Sophia d’Antoine)

RET2 is an RPISEC corporation. Sophia was deeply important to our own founding team, pushing our resolve to embrace the total unknown. RET2 simply would have never manifested had we not been friends. She was beyond remarkable. Her passing weighs heavily on our hearts.

We're now offering professional certificates for completing our fundamentals of software exploitation course on RET2 WarGames! 🎉😱 It'll be challenging, but arguably one of the most rewarding cybersecurity certificates you can hope to obtain: wargames.ret2.systems/certificates

In addition to rolling out training certificates for professionals, RET2 WarGames now offers a lower cost access tier for independent researchers interested in learning binary exploitation through a structured curriculum at-home 🏡🔥

We just added "Mission #0" to our fundamentals of software exploitation training platform🥳 It's a new challenge that combines both reverse engineering and exploitation to comprehensively test your skills on the classical topics of our course: wargames.ret2.systems

This upcoming self-guided hardware hacking course should be awesome, Matt is a top-notch instructor with great materials 👇👇

A few months back we submitted two exploit chains to the first ever Pwn2Own Automotive competition. We just released a blogpost (part 1 of 2) detailing the bugs we abused to remotely exploit the Phoenix CHARX industrial EV charger and win $60,000 🔥🔥 blog.ret2.io/2024/07/17/pwn…

Part 2/2 of our Pwn2Own Automotive exploit writeup for the Phoenix CHARX is now out 🎉 This second post explains how we remotely bypassed ASLR and COP'd our way to a shell. It even includes a GitHub link to the full exploit code. Enjoy! blog.ret2.io/2024/07/24/pwn…

A new, high-production, US-based security conference dedicated to reverse engineering & program analysis. Something like this is long overdue, sharing nothing but hype for this conference 🚀🎉

If a zero-day exploit hits your Sonos smart speakers and nobody is around to hear it, will they really make a sound? 👀 Find out next week at #Pwn2Own Ireland! #RCE #exploit #0day

Confirmed! Jack Dates of RET2 Systems (RET2 Systems) used a single Out-of-Bounds (OOB) write to exploit the #Sonos Era 300 speaker. He earns himself $60,000 and 6 Master of Pwn points. #Pwn2Own #P2OIreland

Confirmed! Jack Dates of RET2 Systems (RET2 Systems) used an OOB Write to get a shell and a modified login page on the Synology DiskStation DS1823xs+. His second round win nets him $20,000 and 4 Master of Pwn points. #Pwn2Own #P2OIreland
