A severe vulnerability, dubbed GPUBreach, that allows attackers to achieve a full system compromise, including a root shell. Scheduled for presentation at the IEEE Symposium on Security and Privacy, researchers from the University of Toronto show that this exploit elevates GPU Rowhammer attacks from simple data corruption to critical privilege escalation. Historically, GPU Rowhammer attacks […]

Cloudflare announced it is targeting 2029 to complete post-quantum security across its entire product suite, including post-quantum authentication. The company is following a revised roadmap that Google also adopted after announcing that it had improved the quantum algorithm used to break elliptic curve cryptography. Google stopped short of publishing the algorithm, disclosing only a zero-knowledge proof of its existence. The same day, a company called Oratomic published a resource estimate for breaking RSA-2048 and P-256 … More →

Reducing Mean Time to Respond (MTTR) is one of the most persistent challenges for modern SOC teams. Despite investments in SIEM, EDR, and automation, many organizations still struggle to investigate alerts quickly and make confident decisions under pressure. The issue is not a lack of tools, it is the growing gap between alert volume and investigation capacity. As threat volume […]
