Cybersecurity researchers have demonstrated yet another variation of the Rowhammer attack affecting all DRAM (dynamic random-access memory) chips that bypasses currently deployed mitigations, thereby effectively compromising the security of the devices. The new technique — dubbed "Blacksmith" (CVE-2021-42114, CVSS score: 9.0) — is designed to trigger bit flips on target refresh … [Read more...] about New Blacksmith Exploit Bypasses Current Rowhammer Attack Defenses

New JavaScript Exploit Can Now Carry Out DDR4 Rowhammer Attacks
Academics from Vrije University in Amsterdam and ETH Zurich have published a new research paper describing yet another variation of the Rowhammer attack. Dubbed SMASH (Synchronized MAny-Sided Hammering), the technique can be used to successfully trigger the attack from JavaScript on modern DDR4 RAM cards, notwithstanding extensive mitigations that have been put in place by … [Read more...] about New JavaScript Exploit Can Now Carry Out DDR4 Rowhammer Attacks
