Cybersecurity researchers from ETH Zurich have developed a new variant of the RowHammer DRAM (dynamic random-access memory) attack that, for the first time, successfully works against AMD Zen 2 and Zen 3 systems despite mitigations such as Target Row Refresh (TRR). “This result proves that AMD systems are equally vulnerable to Rowhammer as Intel systems,

Read MoreA new security shortcoming discovered in Apple M-series chips could be exploited to extract secret keys used during cryptographic operations. Dubbed GoFetch, the vulnerability relates to a microarchitectural side-channel attack that takes advantage of a feature known as data memory-dependent prefetcher (DMP) to target constant-time cryptographic implementations and capture sensitive data from the CPU cache. Apple
