RAMBleed Attack – Flip Bits to Steal Sensitive Data from Computer Memory


A team of cybersecurity researchers yesterday revealed details of a new side-channel attack on dynamic random-access memory (DRAM) that could allow malicious programs installed on a modern system to read sensitive memory data from other processes running on the same hardware.

Dubbed RAMBleed and identified as CVE-2019-0174, the new attack is based on a well-known class of DRAM side channel attack called Rowhammer, various variants [GLitchRAMpageThrowhammerNethammerDrammer] of which have been demonstrated by researchers in recent years.

Known since 2012, Rowhammer bug is a hardware reliability issue that was found in the new generation of DRAM chips.
