Learn How to Build Security Operations Ready for AI-Powered Attacks

Security teams have spent years trying to detect threats faster. AI is changing the harder part: how much time defenders have left to act. Advanced AI models can now help attackers discover vulnerabilities, generate exploit code, and move through weaknesses faster than traditional security processes were built to handle. The challenge is no longer just finding another vulnerability or

New GPUThor Rowhammer Defeats ECC on NVIDIA RTX A6000 to Gain Host Root Access

Academic researchers have disclosed a Rowhammer attack impacting NVIDIA workstation GPUs with GDDR6 memory that defeats error correction codes (ECC), the mitigation NVIDIA recommends against GPU Rowhammer, and enables denial-of-service (DoS) and privilege escalation to a root shell. Dubbed GPUThor, the attack was developed by researchers at the University of Toronto, who hammered four DRAM

Obfuscating IP Addresses as Hostnames, (Tue, Aug 25th)

It is pretty obvious that hostnames can replace IP addresses. Pretty much any software accepting an IP address will also accept a hostname as an argument. Last week, I wrote about scans for the cloud metadata service listening at 169.254.169.254. These scans attempted to exploit Server Side Request Forgery (SSRF) vulnerability. One way to prevent these types of exploits is to filter requests that contain the string "169.254.169.254" or to add this IP to a blocklist of URLs that should not be ac…

Marimo Notebook Flaw Could Run MCP Commands Before Cells Execute in Edit Mode

Marimo has addressed a high-severity security flaw in its notebook software that allowed an attacker to execute an attacker-supplied Model Context Protocol (MCP) command in a specially crafted notebook, according to VulnCheck's CVE Numbering Authority (CNA) record. The CNA record says the command can run as a local subprocess when the notebook is opened in edit mode. The vulnerability, tracked

Hackers breached over 270 Zimbra servers in ongoing attacks

Threat actors have already compromised over 270 Zimbra instances in remote code execution attacks targeting a high-severity Zimbra Collaboration Suite (ZCS) vulnerability. [...]

Frontier AI: Vulnerability Management's Systemic Revolution

Vulnerability management has been a staple of security programs since the dawn of the cybersecurity discipline. The symbiotic relationship between vulnerability and patch management teams has also existed for that time and has gone through waves of contention and thankfulness. While this relationship required thoughtful care and feeding from both sides, both sides were aiming to work toward a
