New GPUThor attack defeats NVIDIA ECC protection for root access
A newly disclosed Rowhammer attack called GPUThor can bypass error-correcting code (ECC) protections on NVIDIA GPUs, enabling denial-of-service (DoS) and root-level privilege escalation. In a paper published by the University of Toronto, researchers say that GPUThor achieves far more practical bit-flip rates than past concepts like their own GPUHammer or GPUBreach, which became irrelevant after ECC was introduced.

GPU mining malware spreads via SEO poisoning, AI chatbots
Threat actors are targeting systems with high-performance computers in an ongoing cryptojacking campaign spread through a coordinated SEO poisoning operation that also manipulated AI chatbot recommendations. The compromise occurs through malicious download pages for utility software typically installed by owners of powerful systems, like CrystalDiskInfo, HWMonitor, Display Driver Uninstaller, FurMark, K-Lite Codec Pack, and PDFgear. […]
New GPUBreach attack enables system takeover via GPU rowhammer
A new attack, dubbed GPUBreach, can induce Rowhammer bit-flips on GPU GDDR6 memories to escalate privileges and lead to a full system compromise. GPUBreach was developed by a team of researchers at the University of Toronto, and full details will be presented at the upcoming IEEE Symposium on Security & Privacy on April 13 in […]
Android gets patches for Qualcomm flaws exploited in attacks
Google has released security patches for six vulnerabilities in Android’s August 2025 security update, including two Qualcomm flaws exploited in targeted attacks. The two security bugs, tracked as CVE-2025-21479 and CVE-2025-27038, were reported through the Google Android Security team in late January 2025. The first is a Graphics framework incorrect authorization weakness that can lead to memory corruption […]
NVIDIA shares guidance to defend GDDR6 GPUs against Rowhammer attacks
NVIDIA is warning users to activate System Level Error-Correcting Code mitigation to protect against Rowhammer attacks on graphical processors with GDDR6 memory. The company is reinforcing the recommendation as new research published by the University of Toronto demonstrates the practicallity of Rowhammer attacks against an NVIDIA A6000 GPU (graphical processing unit). “We ran GPUHammer on an NVIDIA RTX A6000 […]
Qualcomm fixes three Adreno GPU zero-days exploited in attacks
Qualcomm has released security patches for three zero-day vulnerabilities in the Adreno Graphics Processing Unit (GPU) driver that impact dozens of chipsets and are actively exploited in targeted attacks. The company says two critical flaws (tracked as CVE-2025-21479 and CVE-2025-21480) were reported through the Google Android Security team in late January, and a third high-severity vulnerability (CVE-2025-27038) was […]
GPU-powered Akira ransomware decryptor released on GitHub
Security researcher Yohanes Nugroho has released a decryptor for the Linux variant of Akira ransomware, which utilizes GPU power to retrieve the decryption key and unlock files for free. Nugroho developed the decryptor after being asked for help from a friend, deeming the encrypted system solvable within a week, based on how Akira generates encryption […]
ASRock Launches Passive RX 7900 XTX & RX 7900 XT GPUs With Vapor Chamber & 12V-2×6 Connectors
ASRock adds Radeon RX 7900 XTX & 7900 XT GPUs with a completely passive cooling solution and vapor chambers for system integrators. ASRock First To Introduce Passive-Cooled Radeon RX 7900 XTX & RX 7900 XT GPUs ASRock, today launched two new editions of the AMD RDNA 3-based graphics cards in the Radeon RX 7900 lineup. […]
Chinese GPU maker Moore Threads’ MTLink fabric tech challenges Nvidia’s NVLink, can now scale to 10,000 GPUs for AI clusters
More GPUs, more performance. One of Nvidia’s advantages in the data center space is that it not only offers leading-edge GPUs for AI and HPC computing but can also effectively scale the number of its processors across a data center using its own hardware and software. How could you defeat Nvidia if your GPUs are […]
