One day, my automation failed to unpack one of the #CHAES malware samples. I delved deeper to understand the reasons behind the glitch, revealing personal messages and code adjustments along the way. Enjoy the read 😁 morphisec.com/hubfs/Chae$_Ch…

Day 2 of #ZeroDayQuest brought even more hacking, problem-solving, and unforgettable moments. We then went to Carmine’s for incredible food and even better conversation, connecting over exploits, defense strategies, and a shared passion for protecting customers.

Day 1 of the Zero Day Quest Onsite Hacking Event is in the books and we’ve kicked off Day 2. We welcomed top security researchers from around the world to Microsoft’s Redmond campus for a day of live hacking, collaboration, and connection. Researchers worked side-by-side with Microsoft engineers and product teams to identify vulnerabilities across our AI and cloud platforms. Lots of amazing reports and discussions flowed throughout the day—with MSRC, product teams, and the researchers themselves all driving security forward together. After headshots and hacking, we wrapped the day with a Mariners vs. Tigers game in Seattle (tough loss, but the vibes were strong!). We’re incredibly grateful to the security researcher community. Your work makes a real impact in helping protect customers. #ZeroDayQuest

🚀 Thrilled to share that I’ve been invited to Microsoft’s Zero Day Quest event in Redmond, Washington in 2025! 🔥 Over the past year, I’ve reported 4 RCE vulnerabilities and several other security issues to MSRC. Big thanks to @msftsecresponse for organizing this unique event!
