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 rate-enabled DRAM chips with …

A team of security researchers from Google has demonstrated yet another variant of the Rowhammer vulnerability that targets increasingly smaller DRAM chips to bypass all current mitigations, making it a persistent threat to chip security. Dubbed “Half-Double,” the new hammering technique hinges on the weak coupling between two memory rows that are not immediately adjacent …

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 …

Remember rowhammer vulnerability? A critical issue affecting modern DRAM (dynamic random access memory) chips that could allow attackers to obtain higher kernel privileges on a targeted system by repeatedly accessing memory cells and induce bit flips. To mitigate Rowhammer vulnerability on the latest DDR4 DRAM, many memory chip manufacturers added some defenses under the umbrella …

A team of security researchers has discovered a new set of techniques that could allow hackers to bypass all kind of present mitigations put in place to prevent DMA-based Rowhammer attacks against Android devices. Dubbed RAMpage, the new technique (CVE-2018-9442) could re-enable an unprivileged Android app running on the victim’s device to take advantage from …

Last week, we reported about the first network-based remote Rowhammer attack, dubbed Throwhammer, which involves the exploitation a known vulnerability in DRAM through network cards using remote direct memory access (RDMA) channels. However, a separate team of security researchers has now demonstrated a second network-based remote Rowhammer technique that can be used to attack systems …

Exploitation of Rowhammer attack just got easier. Dubbed ‘Throwhammer,’ the newly discovered technique could allow attackers to launch Rowhammer attack on the targeted systems just by sending specially crafted packets to the vulnerable network cards over the local area network. Known since 2012, Rowhammer is a severe issue with recent generation dynamic random access memory …

For the very first time, security researchers have discovered an effective way to exploit a four-year-old hacking technique called Rowhammer to hijack an Android phone remotely. Dubbed GLitch, the proof-of-concept technique is a new addition to the Rowhammer attack series which leverages embedded graphics processing units (GPUs) to carry out a Rowhammer attack against Android …
