12/31/2023 0 Comments Intel fails out to spectre meltdown![]() ![]() “It might sound a little esoteric at first, but it’s actually a very significant threat.” –Mike Chapple (Apple disclosed that all of its Mac and iOS products are affected, except for the Apple Watch.) “The interesting part of this is that it’s so pervasive and affects almost every device that everyone uses,” said Dan Alig, chief information officer of Wharton Computing and Information Technology. They affect not only Intel but major chipmakers AMD and ARM, which powers Apple products, household devices and others. What makes Spectre and Meltdown stand out is the sheer scale of their impact. On January 3, Intel disclosed the flaws publicly, following a story in The Register. Genkin’s group and Horn separately found a security hole called Spectre, while Horn and two other teams found the Meltdown flaw. The chipmaker told them that other groups had independently found the same vulnerabilities as well - notably Jann Horn of Google Project Zero and six others. In December 2017, Kocher notified Intel of their findings. It was then that the enormity of the chip vulnerability hit them. Genkin, who is a post-doctoral fellow at the University of Pennsylvania and University of Maryland, Yarom and Hamburg met Paul Kocher, a well-respected cryptographer. It wasn’t until the following year’s cryptography conference - held this time in Taiwan - that things began to gel. “None of us knew of the implications back in 2016.” “It was just an idea floating around,” Genkin said. During conversations about the work they were doing, they got the idea that the particular way computer chips were designed might be exploited by hackers. ![]() ![]() In the fall of 2016, two Israeli researchers doing work in cryptography and computer security - longtime pals Daniel Genkin and Yuval Yarom - met fellow cryptographer Mike Hamburg at a conference in Santa Barbara, Calif. Northeastern's Andrea Matwyshyn and Notre Dame's Mike Chapple discuss the Spectre and Meltdown chip flaws.
