Critical Node.js Vulnerability Can Cause Server Crashes via async_hooks Stack Overflow

Jan 14, 2026 Application Security / Vulnerability
Node.js has released updates to fix what it described as a critical security issue impacting "virtually every production Node.js app" that, if successfully exploited, could trigger a denial-of-service (DoS) condition. "Node.js/V8 makes a best-effort attempt to recover from stack space exhaustion with a catchable error, which frameworks have come to rely on for service availability," Node.js's Matteo Collina and Joyee Cheung said in a Tuesday bulletin. "A bug that only reproduces when async_hooks are used would break this attempt, causing Node.js to exit with 7 directly without throwing a catchable error when recursions in user code exhaust the stack space. This makes applications whose recursion depth is controlled by unsanitized input vulnerable to denial-of-service attacks." At its core, the shortcoming stems from the fact that Node.js exits with code 7 (denoting an Internal Exception Handler Run-Time Failure ) instead of gracefully handling the...

China-Linked UAT-7290 Targets Telecoms with Linux Malware and ORB Nodes

China-Linked UAT-7290 Targets Telecoms with Linux Malware and ORB Nodes

Jan 08, 2026 Malware / Threat Intelligence
A China-nexus threat actor known as UAT-7290 has been attributed to espionage-focused intrusions against entities in South Asia and Southeastern Europe. The activity cluster, which has been active since at least 2022, primarily focuses on extensive technical reconnaissance of target organizations before initiating attacks, ultimately leading to the deployment of malware families such as RushDrop, DriveSwitch, and SilentRaid, according to a Cisco Talos report published today. "In addition to conducting espionage-focused attacks where UAT-7290 burrows deep inside a victim enterprise's network infrastructure, their tactics, techniques, and procedures (TTPs) and tooling suggest that this actor also establishes Operational Relay Box (ORBs) nodes," researchers Asheer Malhotra, Vitor Ventura, and Brandon White said . "The ORB infrastructure may then be used by other China-nexus actors in their malicious operations, signifying UAT-7290's dual role as an espionage-motiva...
