PortSmash Side Channel Attack Siphons Data From Intel, Other CPUs

Yet another side-channel attack, this time dubbed PortSmash, has been discovered in CPUs. The attack allows attackers to manipulate a glitch in the simultaneous multithreading SMT architecture used in CPUs — and siphon processed data from chips. Several attacks have popped up over the past year...

Side-Channel Attack Steals Crypto Key from Co-Located Virtual Machines

Side-channel attacks against cryptography keys have, until now, been limited to physical machines. Researchers have long made accurate determinations about crypto keys by studying anything from variations in power consumption to measuring how long it takes for a computation to complete. A team of...
