Security researcher @Synacktiv — CTF organizer @sth4ck

Userland iOS aficionados, I released a simple IDA plugin that should improve your Objective-C experience. For now it removes ARC function calls in decompiled code (eg objc_retain) and helps listing candidate callers to a method. Check it out at github.com/synacktiv/objc…

The "Objective-C helper" IDA plugin presented during the @sth4ck talk "Demystifying Objective-C internals" given by @v1csec is now publicly available on GitHub at github.com/synacktiv/objc… The slides are also available on our website: synacktiv.com/sites/default/…

Have you ever wondered what the attack surface of Counter Strike: Global Offensive looks like? Our ninjas @myr463 and @v1csec studied it and found a server to client bug! Read more details about this research in our latest blogpost. synacktiv.com/publications/e…

Our ninja @masthoon solved a tough challenge during @PotluckCTF with an ingenious approach: he built a decompiler for a custom ISA by lifting instructions to Binary Ninja IL. Read the "Pot of Gold" write-up (kudos to @bl4sty for creating the challenge): synacktiv.com/publications/l…

To facilitate reverse-engineering of large programs, vulnerability research and root-cause analysis on iOS, Android, and other major platforms, @myr463 and @Hexabeast released Frinet, a tool combining Frida with an enhanced version of Tenet. synacktiv.com/publications/f…

PhD candidate in Programming Languages nearing thesis submission looking for (ideally remote) positions from Oslo, Norway. Some topics I'm interested in are compilers, verification, security, and cryptography. DM for resume! RTs appreciated😊

We did it 😃! What a blast to be part of a team able to claim the title of Master of Pwn! Kudos to all other participants and to @thezdi for the flawless organization. Let’s wait for the patches, then we’ll share the technical details with the community 🤙

Here are the final Master of Pwn standings. Congrats to @Synacktiv on claiming the title. It was a close race, but they pull through.
