Which memory modules are known to be vulnerable to or secure against Rowhammer/Flip Feng Shui?
Many memory modules from different manufacturers have been tested for vulnerability to the Rowhammer exploit. However, some researchers have anonymised their results, possibly for responsible disclosure reasons. Are there any… Continue reading Which memory modules are known to be vulnerable to or secure against Rowhammer/Flip Feng Shui?

Is rowhammer comparable to faults caused by radiation?
As far as I know, both rowhammer and radiation based fault injection, can cause arbitrary bit flips in the memory.
Are there any differences in matters of possible outcomes of both “attacks” on common hardware?
EDIT: In … Continue reading Is rowhammer comparable to faults caused by radiation?

How can I protect my home/office computer against row hammer?
Row hammer seems to affect ECC memory less, but ECC is still not immune. I have heard of software mitigations like ANVIL, but that doesn’t seem to be 100% row-hammer-proof either.
What software or hardware can reliably protect me against … Continue reading How can I protect my home/office computer against row hammer?
How to disable typed arrays in firefox as rowhammer mitigation
I am concerned about the potential attack surface exposed by JavaScript typed arrays as a means of performing rowhammer attacks.
Is it possible to disable (via official means or otherwise) typed arrays in firefox?
