For our first talk, Ambre presents her previous research about firmware images identification #SSTIC2025
🔥Introducing Arion🔥 A high-performance C++ framework for emulating executable binaries. Based on Unicorn and inspired by Qiling, Arion offers an easy-to-use interface and super low execution times making it a great ally for fuzzing or other applications. github.com/h311d1n3r/Arion
The FastCGI library, mostly used in embedded equipment, was vulnerable for decades to an integer overflow over the IPC socket in 32-bits architecture. Check out how @ShiroPycatchown found it and exploited it for RCE! synacktiv.com/en/publication…
