Instead of relying on covert cache channel, researchers demonstrated NetSpectre attack using the AVX-based covert channel that allowed them to capture data at a deficient speed of 60 bits per hour from the target system. Intel researchers have discovered a new variant of the Spectre vulnerability that , unlike other variants , can launch over a network . Called NetSpectre , an attack could enable attackers to extract data such as passwords , cryptographic keys and other information stored in CPU memory from systems on a network . Researchers reported vulnerability to vulnerability to Intel in March , which came up with a software patch . News of vulnerability came two weeks after Intel paid a $ 100,000 bug bounty for the discovery of new vulnerabilities related to Spectre variant one , while Microsoft and Google reported a variant four vulnerability in May.
