    In 1988, the Soviet Union's first space shuttle - the Buran - blasted off from present-day Kazakhstan. It never went to space again. In 2018, French photographer Jonk snuck into a spaceport in Kazakhstan to capture these images of abandoned USSR shuttles.

    New blogpost: Sanitized Emulation with QEMU-AddressSanitizer I just open-sourced my QEMU patches to fuzz binaries with ASan, QASan. You can also use it with ARM targets on Linux, a thing that you can't do with LLVM ASan!

    Just watched this with my Greek in-laws (one teaches Ancient Greek). General laughter; they thought it was a British stand up comedy or some pantomime. I explained it was meant to be Homer. Uncle Christos and Auntie Dimitra have not recovered yet.

    Looks like kernel memory overwrite at controllable offset with controllable data, reachable by any user (/dev/watch_queue is 0666), reliable and non-racy: Again, you don't need to scream and panic, we are killing it (hopefully) before the release.

    We compiled a long list of Threats to Validity/Relevance in Security Research for our students, building on common sense & our papers on malware experiments and on benchmarking (and inspired by 's excellent blog). Perhaps useful for others?

    If anyone wants to follow along with booting a Clang-built CFI-enabled x86 kernel, I've written up the instructions to build the latest LLVM and 's LTO/CFI/SCS tree. Enjoy!

    Bill Gates just surpassed Jeff Bezos as the richest person on Earth, with a net worth of $110 billion. I struggled to imagine this huge number, so I animated some bar graphs that put it in proportion with other points of reference. The scale is quite stark.
