CVE-2015-0565

CVE-2015-0565 corresponds to a rowhammer memory‑disturbance bug where NaCl and related x86 code could cause cache interactions (via CLFLUSH) to trigger bit flips in DRAM, enabling rowhammer-based exploits. The Connected documents describe two notable exploits: (1) NaCl sandbox escape by abusing b...

A week in security (December 30 – January 5)

Last week on Malwarebytes Labs, we took a dive into edge computing, looked at new web skimmer techniques, and rolled our eyes at silly people doing silly things. Other cybersecurity news: Stills and chills: A Reddit user notices their security camera is grabbing stills from other people’s devices...

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...
