having been raised by crusty linux laptops, i just can't use this OS in good conscious. I feel like a spineless class traitor every time i connect to a monitor or a bluetooth device on the first try

As @EuroSys_conf wraps up, we deeply thank the 64 volunteers that served in the AE committee.
Three were amazing and won the Distinguished Artifact Evaluator Award:
Andrés Sanchez (@andsanmar), Moritz Lumme (@m00wl), Konstantinos Papaioannou (@kon_papaioannou)
Congratulations 🥳

You found a classic stack-based buffer overflow, but you can't exploit it due to stack cookies. Fear not, we have the solution for you, in the post-Spectre era much more is possible: arxiv.org/pdf/2003.05503.pdf

Hey, gadget search using symbolic analysis of binaries is effective as shown by Atri Bhattacharyya from @HexHiveEPFL (@EPFL_en) in #RAID20.
Check their SpecROP paper to learn about Speculative Exploitation of ROP Chains usenix.org/conference/raid20…

🎥@MarcoGuarnier1 talks about #SPECTECTOR, an automated technique for determining whether programs are vulnerable to a specific class of micro-arquitectural attacks called speculative execution attacks. m.youtube.com/watch?v=bEIrX1…

One of the positive factors of attending recorded sessions (lectures, conference talks...) is that you can speed them up if needed 😁

We use automata learning techniques and program synthesis to automatically infer cache replacement policies from real hardware.

Interested in working on fun systems security research problems? The #HexHive @ICepfl @EPFL_en is hiring! We do software security (sanitization, automated testing, mitigations) and hardware security (side channels, GPU, firmware). There's great (free) espresso and retro games!

Existing software may be vulnerable to these side channel attacks with patterns commonly considered as secure, such as dropping all references to a memory location without overwriting its contents althought it won't be referenced again

I've worked in this project during my summer internship at the @MIT_CSAIL, knowing awesome people. I would want to thank everyone who has made possible to me to receive a grant from which this work results, specially people at @IMDEA_Software and @La_UPM

These are the students who invited me to Madrid for a category theory sprint (5 lectures in 5 days seminars on selected papers). It was a wonderful week culminating in a feast in Segovia.
