    Re-reading the Lest We Forget paper on defeating DDR3 scrambling in cold-boot attacks and it raises a question: 6 years have passed; has anyone attempted to replicate the work for DDR4 on a modern CPU & PCH?

    t turned out that the receiver had a tight filter; as little as 5 kHz of error was enough to result in failure. HackRF One's crystal can be up to 20 ppm off, resulting in as much as 9 kHz error at the target frequency (443 MHz). Adding a small offset corrected the problem. 2/2

    Multiple teams used HackRF One with a PortaPack for a POCSAG pager transmit challenge at the . Some worked; some didn't. This intrigued me! 1/2

    This is really cool...just the stdlib but it’s a LOT of versions. I wish we could do this with Keil stdlibs w/o violating ToS

    to drag on that point about random bytes a bit, i took 256 bytes from /dev/urandom and disassembled them as 8051. there's "code"! it's got jumps! calls! if you aren't paying attention, you can so easily be tricked into thinking it's just complex code you don't yet understand 😬

    You have a partial ARM Cortex something firmware. No access to the hardware. What interesting ways can you think of working out which MCU it is for?

    I brought one hundred NFC Type 5 microcontroller boards to Shmoocon, which are OTA programmable from Android. You can have one for free if you install the compiler toolchain documented on the Github page.

    Just published a follow-up to my Adobe Reader symbols story on the Project Zero blog. Turns out there's even more debug metadata to be found in some old (and new) builds, including private CoolType symbols. Enjoy!

    If you're not familiar with you can check out a talk here: Basically it's all of Debian jessie packages built for all supported arches (x86, ARM, MIPS, PPC, s390) - retaining compiler debug output, intermed. object files and symbols
