Happy to have presented our SECUBIC project to the French research community in system security (RESSI'25)! 🏠 secubic-ptcc.github.io 🧑🔬 @Seb_Bardin @Jean_YvesMarion Stefano Zacchiroli Thanks to the RESSI organizers who had even provided a pool to finish my #OOPSLA reviews! 😇
Check out our ROSARUM benchmark, part of our #icse2025 paper on backdoors and fuzzing: ▶️ It is a fuzzing benchmark (can fuzzers trigger backdoors reliably and fast?) ▶️ It is a backdoor detection benchmark (can code analyses find backdoors reliably?) ⬇️ github.com/binsec/rosarum
How to detect backdoors efficiently? 🗣️ The slides of our #icse2025 presentation on "Finding Backdoors with Fuzzing" are now available at ⬇️ binsec.github.io/assets/publica…
Very honored to receive the Best Artifact award at #icse2025 🥳 Congrats and thank you to my coauthors! @michaelmarcozzi, Emilien Decoux, Stefano Zacchiroli

"Finding backdoors with fuzzing" --> presentation at @ICSEconf on Friday at 4pm by the great @plumtrie! 👇
On my way to Ottawa and @ICSEconf 🍁 Presenting on Friday (May 2nd) at 16:00 local time in room 210, come say hi ☺️
JOB OFFER! - Liked our work on finding backdoors with fuzzing? Then, join the team as a postdoc and help us fight binary supply-chain attacks! We offer a stimulating and open-minded scientific environment in English, in wonderful Paris! APPLY AT secubic-ptcc.github.io/jobs/open/2025…
How to detect backdoors efficiently? ▶️ Backdoors were found in firmware & open-source code ▶️ Detection requires much manual reverse-engineering ▶️ Fuzzers cannot see backdoors Our @ICSEconf preprint on finding backdoors with fuzzing is at binsec.github.io/nutshells/icse… A thread ⬇️
📢 I am looking for a postdoc on fuzzing, to prevent backdoors and supply-chain attacks! Come and join the team here in Paris (or spread the word)! 🙂 Details and application: secubic-ptcc.github.io/jobs/open/2025…
