New PlunderVolt Attack Targets Intel SGX Enclaves by Tweaking CPU Voltage
A team of cybersecurity researchers demonstrated a novel yet another technique to hijack Intel SGX, a hardware-isolated trusted space on modern Intel CPUs that encrypts extremely sensitive data to shield it from attackers even when a system gets compromised. Dubbed Plundervolt and tracked as...
RAMBleed attack steals sensitive data from computer memory
By Waqas "RAMBleed Reading Bits in Memory Without Accessing Them." A team of security researchers has published a report on a relatively advanced and previously undetected variant of the Rowhammer attack called RAMBleed. Researchers claim that the new variant can be used for reading the contents ...
RAMBleed Side-Channel Attack Exposes Privileged Memory
A team of academic researchers has discovered a follow-on to the Rowhammer class of attacks that allows attackers to read memory data on a target Windows computer, without actually accessing the memory itself. The method is dubbed RAMBleed. Andrew Kwong and Daniel Genkin at the University of...
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...
