“TRRespass” is a new trick for rowhammering – an attack where you write to a memory chip by reading it over and over (and over) again. Continue reading TRRespass research reveals rowhammering is alive and well
The attack allows malicious applications to break out of their sandbox and access the entire operating system, giving an adversary complete control of the targeted device. Continue reading Rowhammer Variant ‘RAMpage’ Targets Android Devices All Over Again

We love squeezing every last bit of silicon goodness out of a tiny chip, or at least we delight in seeing it done. Today’s analog/digital hack is one of the sweetest we’ve seen in a while. And it’s also a little bit of a puzzle, so don’t scroll down to the answer until you’ve given the schematic a good think-over.
[Claudio Larios] built a tachometer with LCD display, using only an eight pin PIC microcontroller for brains. (Translatrix.) Two pins are taken up by the power supply and one reads a Hall sensor, leaving only three pins to drive an …read more
Existing crypto software “wholly unequipped” to counter Rowhammer attacks. Continue reading New cloud attack takes full control of virtual machines with little effort
Approach relies on already installed code, including widely used glibc library. Continue reading DRAM bitflipping exploits that hijack computers just got easier
A few weekends ago, [Chris] was in the mood for some retrogaming. That meant digging out the old Apple IIgs equipped with a monstrous RAM card with a whole three megabytes of RAM. This particular Apple IIgs had intermittent issues for a long time, and [Chris] was beginning to suspect the RAM was the culprit. Testing this required testing a few dozen individual RAM chips, so why not build something with an Arduino to make [Chris]’ life easier?
The chips found in [Chris]’ Apple are standard 1 M x 1 DRAM chips, the standard for late-80s computers. To test these …read more
New research finds “bitflipping” attacks may pose more risk than many admit. Continue reading Once thought safe, DDR4 memory shown to be vulnerable to “Rowhammer”
