NetSpectre Highlights New Ways to Exploit Speculative Execution

NetSpectre is not an immediate threat: no known malware exists in the wild. The research is important because it deepens our understanding of microprocessor architecture and ways speculative execution can be abused.

Expect More Spectre, Meltdown Variants Until Updated Chips Arrive

After Meltdown and Spectre, many researchers warned that increased scrutiny on side-channel meant more attacks will be found, so the discovery of "Variant 4" is not a surprise. More variants will be found as chip makers update their designs over the next few years to fix the issues.

BranchScope: Another Processor-Based Attack

Much like Spectre, BranchScope is an attack that focuses on the processor's branch prediction system. That doesn't mean the processors are hopelessly vulnerable. It just means that as more researchers start exploring various features in modern CPUs, more issues will be found.
