The Russia-linked threat actor known as APT28 (aka Forest Blizzard) has been linked to a new campaign that has compromised insecure MikroTik and TP-Link routers and modified their settings to turn them into malicious infrastructure under their control as part of a cyber espionage campaign since at least May 2025. The large-scale exploitation campaign has been codenamed 

Hackers linked to Russia’s military intelligence units are using known flaws in older Internet routers to mass harvest authentication tokens from Microsoft Office users, security experts warned today. The spying campaign allowed state-backed Russian hackers to quietly siphon authentication tokens from users on more than 18,000 networks without deploying any malicious software or code. Microsoft said in a blog post today it identified more than 200 organizations and 5,000 consumer devices that were caught up in a stealthy but remarkably simple spying network built by a Russia-backed threat actor known as “Forest Blizzard.” How targeted DNS requests were redirected at the router.

A high-severity security vulnerability has been disclosed in Docker Engine that could permit an attacker to bypass authorization plugins (AuthZ) under specific circumstances. The vulnerability, tracked as CVE-2026-34040 (CVSS score: 8.8), stems from an incomplete fix for CVE-2024-41110, a maximum-severity vulnerability in the same component that came to light in July 2024.

An active campaign has been observed targeting internet-exposed instances running ComfyUI, a popular stable diffusion platform, to enlist them into a cryptocurrency mining and proxy botnet. "A purpose-built Python scanner continuously sweeps major cloud IP ranges for vulnerable targets, automatically installing malicious nodes via ComfyUI-Manager if no exploitable node is already

In the rapid evolution of the 2026 threat landscape, a frustrating paradox has emerged for CISOs and security leaders: Identity programs are maturing, yet the risk is actually increasing. According to new research from the Ponemon Institute, hundreds of applications within the typical enterprise remain disconnected from centralized identity systems. These "dark

When talking about credential security, the focus usually lands on breach prevention. This makes sense when IBM’s 2025 Cost of a Data Breach Report puts the average cost of a breach at $4.4 million. Avoiding even one major incident is enough to justify most security investments, but that headline figure obscures the more persistent problems caused by recurring credential

New academic research has identified multiple RowHammer attacks against high-performance graphics processing units (GPUs) that could be exploited to escalate privileges and, in some cases, even take full control of a host. The efforts have been codenamed GPUBreach, GDDRHammer, and GeForge. GPUBreach goes a step further than GPUHammer, demonstrating for the first time that

A China-based threat actor known for deploying Medusa ransomware has been linked to the weaponization of a combination of zero-day and N-day vulnerabilities to orchestrate "high-velocity" attacks and break into susceptible internet-facing systems. "The threat actor's high operational tempo and proficiency in identifying exposed perimeter assets have proven successful, with recent

Threat actors are exploiting a maximum-severity security flaw in Flowise, an open-source artificial intelligence (AI) platform, according to new findings from VulnCheck. The vulnerability in question is CVE-2025-59528 (CVSS score: 10.0), a code injection vulnerability that could result in remote code execution. "The CustomMCP node allows users to input configuration settings for connecting

An Iran-nexus threat actor is suspected to be behind a password-spraying campaign targeting Microsoft 365 environments in Israel and the U.A.E. amid ongoing conflict in the Middle East. The activity, assessed to be ongoing, was carried out in three distinct attack waves that took place on March 3, March 13, and March 23, 2026, per Check Point. "The campaign is primarily
