Researchers say they used a new Rowhammer exploit to successfully flip bits on all 40 PC-DDR4 DRAM devices they tested, defeating recent hardware mitigations

We demonstrate that it is possible to trigger Rowhammer bit flips …

    Any RAM chip that can't handle arbitrary reads and writes at its documented speed should be considered defective. https://arstechnica.com/...

    Rowhammer attacks are so cool, because they're right at the point where software and hardware are the same physical thing. https://arstechnica.com/...

    This is cool new research but those mitigations had already been busted for some RAM tech a few years back. On the other side, I'm curious how some of you security folks rank Rowhammer on your threat vectors/matrices. Did you ever take it seriously? https://twitter.com/...

    seems like there's an increasing rate of discovering hardware exploits in recent years https://comsec.ethz.ch/...
