Gaslights produce a telltale flicker when nearby lamps are lit; DRAM values do something similar when nearby memory cells are accessed. Continue reading Serious Security: Rowhammer returns to gaslight your computer
I’ve been looking into rowhammer attacks and mitigations and there are two (what seem to be) mitigations that I’ve seen that are actually implemented in currently available hardware and software, but aren’t mentioned in any studies I’ve se… Continue reading Rowhammer mitigations in current hardware and software
Rowhammer has a new variant. And it’s been made easier: DDR4 memory is getting denser, so the individual bits are physically closer together.

“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
