Time to get your life together and stop putting things off. Final week to register for BlueHat IL. It's gonna be awesome: microsoftrnd.co.il/bluehatil/home
Also joining BlueHatIL: @0xgalz & @ido__shani with ChainLeak: From AI Framework to Cloud Secrets - a fascinating behind-the-scenes look at the vulnerabilities they uncovered in Chainlit, and what we can learn from them. Don't miss. Register now: microsoftrnd.co.il/bluehatil/home
The pretty amazing @idofrizler is bringing the heat to BlueHatIL with a special talk about how Azure Networking uses AI agents to build a production system for automating vulnerability triage at cloud scale. Register now: microsoftrnd.co.il/bluehatil/home
We have absolutely no intention of helping with goal #1. It’s a dumb project and a questionable use of time. Also, let’s be honest - Quake was the better game anyway. Goal #2 though? Sign up: microsoftrnd.co.il/bluehatil/home
Cyber people, the most important reminder of the month: BlueHatIL is happening on June 23–24 - and even if you registered for the original dates, you’ll still need to register again for the updated event. Yes, again. We know❤️ Register here: microsoftrnd.co.il/bluehatil/home
No one dives as elegantly into pure math & national defense strategy as @DanielBachmat - and luckily for us, he’s coming to BlueHatIL to blow our minds with the hidden war for the spectrum, from WWII deception to Starlink and beyond. Register now: microsoftrnd.co.il/bluehatil/conf…
Due to the current situation, we’ve decided to postpone BlueHat IL 2026. We’ll share a new date when possible. Until then - take care and stay safe 💙
Last call for BlueHat IL. 1 week left to register - move now before it’s too late: microsoftrnd.co.il/bluehatil/conf…
Life and death of a CPU bug Racing and Fuzzing HTTP/3 Two Tales of hacking 90s MS-DOS Software And that’s only 3 talks out of dozens across two intense days at BlueHat IL next month. Check out the full lineup and register now: microsoftrnd.co.il/bluehatil/conf…
Less than a month to go. The world’s top cyber minds, the wildest and most creative challenges yet - and hopefully you too, if you sign up before registration closes: microsoftrnd.co.il/bluehatil/home
People, seriously, you know you wanna go to BlueHat IL 2026 next month, so why play all these unnecessary games and put off tasks that take literally 30 seconds? Just jump on the link, sign up, and done: microsoftrnd.co.il/bluehatil/home
The wait is over! Registration and the full agenda for BlueHatIL 2026 are now live. Register now before spots are gone! Register here: aka.ms/BlueHatILRegis… Full agenda: microsoftrnd.co.il/BluehatIL/home
Last chance: microsoftrnd.co.il/bluehatil/conf…
It’s now or never. Only 2 days left to submit your paper to BlueHat IL: microsoftrnd.co.il/bluehatil/conf…
We can’t help much with the first two. But for #3, just go here: microsoftrnd.co.il/bluehatil/conf…
No more excuses, folks. Got research worth sharing? Go big with a 30–40 min main-stage talk - or keep it sharp with a 10-min Lightning Talk. BlueHatIL has a stage for you. CFP is still open: microsoftrnd.co.il/bluehatil/conf…
The new ugly sweater could be yours! Submit a paper to BlueHatIL by Jan 7, and you might win Microsoft’s ultra-limited ugly holiday sweater. Just in case you needed extra motivation: microsoftrnd.co.il/bluehatil/conf…
