Dataflow Security has officially opened a position for a Web Security Researcher. dfsec.com/careers/
Apparently @offensive_con worked their asses off to get their talks up on YouTube Go check them out And here's the coolest talk, my talk: youtu.be/LAIr2laU-So?si… And with that, the full chain used to exploit the S24 is released. Yay!

Vulnerability research is a marathon, not a sprint. Many start out strong but can't keep up the motivation when the going gets tough and the bugs are not flowing. Don't rush it. Be consistent. Keep your pace. You'll get there.
I've written a post on SELinux and some public bypasses for Android kernel exploitation. It's especially relevant for Samsung and Huawei devices due to their use of hypervisors. Check it out here: klecko.github.io/posts/selinux-…
We at @dfsec_com are currently looking for a senior Linux kernel researcher, feel free to DM if you’re curious :)
The time has come, and with it your reading material for the week. Phrack #71 is officially released ONLINE! Let us know what you think! phrack.org/issues/71/1.ht…
Just arrived at @defcon If you're around and want to meet up, hit me up. Would love to connect with some fellow hackers 🏴☠️
You Can't Spell WebRTC without RCE - Part 2 blog post, which turns the vulnerabilities we injected in Part 1 into remote code execution on iOS 16.4! Follow along with @__comedian to learn more about the iOS shared cache, Corellium, and ROP in ARM64! margin.re/2024/07/you-ca…

Love the story @Laughing_Mantis! Bug hunting truly is a roller coaster, and your tweet captures exactly why it’s so much fun! It’s also a great reminder that persistence is key in this work :-D

Thanks to events like Pwn2Own or our V8CTF (~= exploit bounty program), we now have more data about the types of bugs exploited in V8. Based on that, we've gathered some basic statistics: docs.google.com/document/d/1nj…
The libarchive e8 vulnerability is actually really cool, but the ZDI advisory doesn't explain why it's so wild lol. For some reason, I know about RAR filters, so let me provide the background. 🧵 1/n
PHP just fixed one of my RCE vulnerabilities, which affects XAMPP by default. Check to see if you are affected and update now! 🔥 blog.orange.tw/2024/06/cve-20…
