Rowhammer comes to MLC NAND flash


Holy grail for hackers


Two years after Google showed how Rowhammer attacks could flip dynamic random access memory (DRAM) bits to induce those memory cells to change their state, IBM has shown how it can target MLC NAND flash memory.

Giant bug eats DDR4


Rowhammer not just for DDR3

DDR4 was supposed to be a lot more secure than other DDR3 which was vulnerable to an exploit called Rowhammer.  But it turns out that DDR4 might also be vulnerable afterall.
