Congratulations!
Another collision! @fluorite_pwn, @YunjeShin, @yskm_Gunter, @Mafty5275, @clay419, @vvsy46, and @won6_choi of BoB::Takedown targeted the Grizzl-E Smart 40A, hitting one collision and one unique 0-day, earning $15,000 USD and 3 Master of Pwn points. #Pwn2Own #P2OAuto

Congregation! They are our mentees who studied in the 13th BoB (Best of Best) offered by Kitri of Korea.
Confirmed! Their enthusiasm was rewarded as they used an integer overflow to escape #Oracle VirtualBox and execute code on the underlying OS. They earn $40,000 and 4 Master of Pwn points. #Pwn2Own #P2OBerlin

And that bring Day One of #Pwn2Own Berlin to a close. We awarded $260,000 today, but more great research is yet to come. STAR Labs has an early lead on Master of Pwn, but it's anyone's game at this point. Stay tuned for more results as we go.
Congratulations, my coworkers!
We have another collision. Hyunwoo Kim (@v4bel) and Wongi Lee (@_qwerty_po) of Theori were able to escalate to root on Red Hat Linux with an info leak and a UAF, but one of the bugs used was an N-day. They still win $15,000 and 1.5 Master of Pwn points. #Pwn2Own

Guest Revolution: Our Story of Compromising the Host Kernel from the VMware Guest by @bbbig12 & @pr0Ln #HEXACON2024
Our CFP was accepted by hexacon. See you in Paris! #hexacon
During #Pwn2Own Automotive, the team from @Synacktiv used 2 bugs to take over the #Autel Maxicharger. Our latest blog takes a brief look at how they did it, and how Autel patched it. zerodayinitiative.com/blog/2024/8/22…
Debugging Hyper-V: 1. Halt in hvix64. 2. Set VM Resume breakpoint. 3. Turn on Intel Processor Trace. 4. Break in the Secure Kernel. Record all Intel PT executed instructions by reading Host mode memory from within Guest mode. Hopefully cool video for hypervisor enthusiasts.
@_qwerty_po Please buy and bring a new bug for me as a present when you return.😉
🚨 solid writeup on CVE-2024-21338! Learn how a clever AppLocker driver exploit bypasses SMEP & kCFG. Two paths to SYSTEM access revealed. Worthy read! Great work by @crowdfense crowdfense.com/windows-apploc…
