Learn how Google CVR could have potentially exfiltrated Gemini 1.0 Pro before launch last year. We describe the vulnz, the fix, and tips for bughunters. Also, shout-out to @epereiralopez for teaming up to adapt this work to another cloud provider. bughunters.google.com/blog/5…
Today our Cloud Vulnerability Research (CVR) team shared this research into LLM security, which is broadly applicable to AI domain security practitioners working in this rapidly evolving space. Learn more: bit.ly/3TWYrF3

🕺"Leaving tradition" is one of the best parts of Google's security culture and has led to some of the most interesting attack chains I've gotten to work on. There's nothing quite like starting with a blank slate and ending with a root shell.💃

Before joining Google, I submitted some Cloud bugs to the Google Vulnerability Rewards Program (VRP). Today, we announced a dedicated Cloud VRP and I'm so excited to be a part of the program that got me into Google in the first place. Send us vulnz 🙂 cloud.google.com/blog/produc…

Excited to share this blog post about server-side memory corruption that my team exploited in production. Shout-out to @scannell_simon, @epereiralopez, and @thatjiaozi - this was a very fun project. :-) bughunters.google.com/blog/6…

Very excited to present this with @amlweems! See you in Berlin! (@epereiralopez and @thatjiaozi) were also working on that project and will also be there :)

I've been reverse engineering the xz backdoor this weekend and have documented the payload format and written a proof-of-concept exploit for the RCE. The payloads are signed with an ED448 key, so I patched my own key into the backdoor for testing. :-) github.com/amlweems/xzbot

github.com/google/security-r… Our research on the deep mines of the JPX standard is now public. I had the pleasure and the privilege to work with @scannell_simon , @amlweems and @epereiralopez on this one. Pretty interesting client side info leak vector :)

I'm really excited for this video! I got a chance to collab with @LiveOverflow and share the process for discovering the localhost bypass for CVE-2021-45046 with code review and differential fuzzing. :)
After the log4shell vulnerability was patched with version 2.15, another CVE was assigned. Let's have a closer look at the localhost JNDI connections bypass and learn about fuzzing Java applications. youtube.com/watch?v=kvREvOvS…

Just finished Portswigger's new Burp Suite Certification. I've always been a huge fan of the @WebSecAcademy and this is an excellent capstone on the labs. Thanks @PortSwigger for all the educational content! #burpsuitecertified

Thanks for the seamless contribution process! Cheers to @BouncyHat and @dallasl1200 😄
Thanks to @amlweems, Michael Weber, and Dallas Kaman for performing an analysis on CVE-2021-26855, the Microsoft Exchange SSRF vuln! googleprojectzero.github.io/…

My team @praetorianlabs just published our work in reverse engineering the Proxylogon patches for CVE-2021-26857, CVE-2021-26855, and CVE-2021-27065. I learned a lot more about Exchange than I thought I'd ever need, but had a blast. praetorian.com/blog/reproduc…

Awesome new work from @albinowax on cache poisoning. Cache Key Injection especially feels like it should have some interesting variants. portswigger.net/research/web…

Also, some great new labs on @WebSecAcademy to go along with the research. Thank you for continuing to create free educational content like this. portswigger.net/web-security…
