Gonna be giving a talk "SLUB Internals for Exploit Developers" at @LinuxSecSummit next week. Plan to cover the basics one needs to know before writing exploits for slab bugs; slides coming along 😁 Also gonna stay around for @linuxplumbers. lsseu2024.sched.com/event/1ebVN
Just a few days left to apply to our PhD and PostDoc positions available at @vu5ec. If you love low-level systems hacking and would you like to work at a top systems security research group in Amsterdam, consider applying: workingat.vu.nl/vacancies/phd-…
This took a significant amount of time and money, and now we know what DRAM vendors are doing in their sense amplifiers! Lots of research opportunities moving forward. All the images and the reverse engineered circuits are now publicly available.
For the first time, we imaged and reverse engineered 6 modern DDR4/5 DRAM chips (comsec.ethz.ch/hifi-dram) Due to the incredibly small feature size of modern ICs, we use SEM combined with FIB reaching pixel resolutions as low as 3.4nm. Then we evaluate 10 years of DRAM research.

Branch History Injection (BHI) is back! Disclosing Native BHI, bypassing deployed Spectre-v2/BHI mitigations (e.g., eBPF=off) to leak arbitrary kernel/host memory (e.g., root password hash below). Joint work by @SanWieb @HBitmasks @herbertbos @c_giuffrida: vusec.net/projects/nativ…

Should we lose hope already on Rowhammer attacks? Andrea Di Dio from Vrije Universiteit Amsterdam is showing us at #NDSS23 that it is feasible to devise a software-based design to mitigate ECC-aware Rowhammer attacks.
Happy to share that my latest paper, Copy-on-Flip, has been accepted @NDSSSymposium. If you're interested in #Rowhammer defenses you can check it out here:download.vusec.net/papers/cof_nds…. Big thanks to the other authors who helped out on the paper: Koen Koning, @herbertbos @c_giuffrida.

Buzzing to announce that I have completed my MSc and have started my PhD at @vu5ec last week. I am very grateful for the opportunity given and thrilled to continue to do research on topics I am passionate about.
Please vaccinate. I have no desire to learn the entire Greek alphabet.
📢 THE TIME HAS COME📢 Today I make public ALL *recordings* and updated slides (+ FAQ) for my mobile security class, MOBISEC 2020! Everything is available, for free, at: mobisec.reyammer.io/slides! Few words about this release in a short thread 👇
OK I didn't appreciate how jam-packed this thing is from @iFixit teardown photos. Also it's 0.3mm PCB so I'm pretty sure I broke some solder joints getting it out. Test pads are accessible w/o removing PCB so if this one isn't working will test another one.
New motivational blogpost + slides, this time on self-confidence, the noob mindset, and tip & tricks for CTFs! (Target audience: young students) 'From Noob to Less Noob: "Wisdom" from 10 years of CTFs' reyammer.io/blog/2021/04/0… Hope you find at least one good idea, enjoy! :-)
