Researchers have discovered a new side-channel attack method that can be launched against devices with Intel processors, and the patches released in response to the Spectre and Meltdown vulnerabilities might not prevent these types of attacks.
The new attack, dubbed BranchScope, has been identified and demonstrated by a team of researchers from the College of William & Mary, University of California Riverside, Carnegie Mellon University in Qatar, and Binghamton University.
Similar to Meltdown and Spectre, BranchScope can be exploited by an attacker to obtain potentially sensitive information they normally would not be able to access directly. The attacker needs to have access to the targeted system and they must be able to execute arbitrary code.
