Turning off email images should at least stop the pictures. This week, attackers had a workaround: a scannable QR code built out of text. It still appears, even with images blocked. A small detail, but an annoying one if that was a precaution you were counting on. Elsewhere, a trusted software source delivered code that stole credentials, and a protocol designed for secure network management

If managing security across multiple cloud providers wasn't hard enough, each one fails in a different way. For the 2026 Cloud Security Index, Intruder analyzed misconfiguration data from 3,000 organizations across AWS, Azure, and Google Cloud and found that risk profiles across providers have almost nothing in common. Here’s what the data looks like. How risk differs across cloud providers

Cybersecurity researchers have disclosed details of worm-like activity that abuses ConnectWise ScreenConnect to distribute a malicious Visual Basic Script (VBScript) payload to newly connected systems. According to Huntress, three unrelated incidents have been found to use diverse initial access methods, namely a Quick Assist tech-support scam, a phishing-delivered MSI installer, and a fake

A TantoSec proof-of-concept turns an AES-CBC "padding oracle" in Telerik UI for ASP.NET AJAX into unauthenticated remote code execution — but only against applications in a specific non-default configuration, and Progress patched the chain in July. There are no confirmed reports of exploitation in the wild. Security firm TantoSec has published a working exploit chain targeting vulnerabilities

Every on-premises N-central build below 2026.3.1.14 — including servers updated to Hotfix 3 a day earlier — needs Hotfix 4. N-able's incident notice says the flaw has been exploited in the wild; its release notes say that is unconfirmed. N-able has released its fourth hotfix in five weeks for the N-central remote monitoring and management (RMM) platform, this time for a

Cybersecurity researchers have unpacked JSCeal, a sophisticated compiled V8 JavaScript (JSC) malware with credential harvesting, surveillance, and traffic-interception capabilities. "The payloads are protected with javascript-obfuscator, using multiple techniques including RC4-protected strings, control-flow flattening, proxy functions, and operation wrappers," Check Point Research said in a
