It's time to F5! Conference tickets will go on sale in a few minutes 🔥 hexacon.fr/register/
🔥 Excited to announce our keynote! We are thrilled to welcome Bruce Dang (@brucedang) and Thai Duong (@XorNinja) from @calif_io! With all their recent AI buzz, we had to check they aren't just LLMs in a trench coat. 🤖🧥 🎟️ Ticketing opens this Thursday at 2:00 PM CEST ⏰
Offensivecon's talks are now available on our YouTube channel! 🔗 buff.ly/g63xgm5

RIP for all 6 entries. The last-minute patch turned out quite solid. So I decided to give my exploit a proper goodbye. Enjoy! github.com/kiddo-pwn/ffff…
6 Firefox entries at pwn2own. 5 withdrawals due to our 150.0.3 security release. 1 failed attempt. 0 Exploits. No incidents. Time to party :)
That's my chain — a full chain w/ logic bugs only! No memory corruption, no AI, and of course no collisions at all 😉
Confirmed! Orange Tsai (@orange_8361) of DEVCORE Research Team (@d3vc0r3) chained 4 logic bugs to achieve a sandbox escape on Microsoft Edge, earning $175,000 and 17.5 Master of Pwn points. Full win! #Pwn2Own #P2OBerlin
🚗🔌 @Tesla patched our #Pwn2Own Automotive 2025 Wall Connector exploit with an anti-downgrade mechanism. #Synacktiv experts bypassed it and replayed the same attack through the charging cable. Part 2 write-up👇 synacktiv.com/en/publication…
It's live! ➡️ hexacon.fr/register/
Make it blink! This new article unpacks how Mehdi and Matthieu achieved an over-the-air exploitation of the #PhilipsHue Bridge via a #Zigbee bug. Read all about the technical details, how they proved it is exploitable at #Pwn2Own Cork 2025, and the underlying vulnerability here 👇 synacktiv.com/en/publication…
This second blogpost concludes @yaumn_'s research on #Windows authentication reflection. He discloses the new Kerberos authentication coercion technique he discovered to remotely compromise Windows systems 💥 A little bonus is even included at the end 👀👇 synacktiv.com/en/publication…
Authentication reflection attacks are still not dead! In our new blogpost series, @yaumn_ shares his journey into bypassing the mitigations of CVE-2025-33073 to pop SYSTEM shells again🚀 👇 synacktiv.com/en/publication…
The training lineup for Hexacon 2026 is now available on our website 🧑🏼🏫 Training tickets sales will officially launch in mid-May 🎫 hexacon.fr/trainings/
So glad to finally be able to present this research at @BlackHatEvents Asia! Blogposts are coming soon, on the menu: LPE via local NTLM reflection and RCE via a new arbitrary Kerberos authentication coercion technique 👀
Tomorrow, @yaumn_ will be presenting his research on Windows authentication reflection at @BlackHatEvents Asia 2026 in Singapore! The talk will be at 15:20 local time in Simpor Junior Ballroom 4810, come say hi! 😄 #BHASIA ℹ️ blackhat.com/asia-26/briefi…
Mozilla says Mythos helped identify 271 vulnerabilities in Firefox 150. I went through the commits, CVEs, and bug links to see what that number really means. My takeaway: relax folks. xark.es/b/mythos-firef…
The #FCSC2026 ended today, and my write-ups are now available here: mizu.re/post/fcsc-2026… 🚩 I'm really happy with the challenges I managed to create this year! It would be too long to list everything, so here's a little teaser 👇 1/2
The #FCSC2026 ended today, my write-ups are now available on my website worty.fr, don't hesitate to check them !
For this year’s FCSC, I’m proud to have had the opportunity to develop four web challenges: - Shellfish Say - FCSC Aquarium - Secure Mood Notes (Part 1 & 2) There are many more challenges available (created by @kevin_mizu and @BitK_), so don’t hesitate to give them a try! :)
