Grafana Patches AI Bug That Could Have Leaked User Data

By hiding malicious instructions on an attacker-controlled Web page, AI could ingest orders as benign and return sensitive data to the attacker's server.

A Little Bit Pivoting: What Web Shells are Attackers Looking for?, (Tue, Apr 7th)

Webshells remain a popular method for attackers to maintain persistence on a compromised web server. Many "arbitrary file write" and "remote code execution" vulnerabilities are used to drop small files on systems for later execution of additional payloads. The names of these files keep changing and are often chosen to "fit in" with other files. Webshells themselves are also often used by parasitic attacks to compromise a server. Sadly (?), attackers are not always selecting good passwords either. In some cases, webshells come with pre-set backdoor credentials, which may be overlooked by a less sophisticated attacker. 

Russia Hacked Routers to Steal Microsoft Office Tokens

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.

Russian State-Linked APT28 Exploits SOHO Routers in Global DNS Hijacking Campaign

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 

Docker CVE-2026-34040 Lets Attackers Bypass Authorization and Gain Host Access

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.

Over 1,000 Exposed ComfyUI Instances Targeted in Cryptomining Botnet Campaign

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

[Webinar] How to Close Identity Gaps in 2026 Before AI Exploits Enterprise Risk

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

The Hidden Cost of Recurring Credential Incidents

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 GPUBreach Attack Enables Full CPU Privilege Escalation via GDDR6 Bit-Flips

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

China-Linked Storm-1175 Exploits Zero-Days to Rapidly Deploy Medusa Ransomware

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

Flowise AI Agent Builder Under Active CVSS 10.0 RCE Exploitation; 12,000+ Instances Exposed
