Zombieload: Intel CPU exposure of a new side channel attack-exploit warning-the black bar safety net

! Security personnel recently discovered for Intel processor of the new side channel attack, which is also following the earlier Meltdown, the Spectre and Foreshadow after a fairly serious security problems. This vulnerability may allow an attacker to obtain the current processor is processing th...

hardware: Micro-architectural Load Port Data Sampling - Information Leak (MLPDS)

Microprocessors use a ‘load port’ subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPU’s pipelines. Stale load operations results ar...

HA-CFI Technique Checks Mitigation Bypasses Earlier

LAS VEGAS — It wasn’t long ago that ROP, or return-oriented programming, was a hacker’s best friend when it came to bypassing mitigations against memory-based attacks such as DEP and ASLR. ROP, however, is so 2005. In the last couple of years, researchers and attackers have figured out how to...
