The North Korean threat actor known as Lazarus Group has been attributed to the zero-day exploitation of a newly patched security flaw impacting Microsoft Windows to deliver a never-before-seen backdoor targeting defense and aerospace companies across France, Germany, Brazil, and India. The activity, per Check Point Research, is part of Operation Dream Job, a long-running cyber espionage and

A massive set of 737 free VPN and proxy extensions have been found to mainly target Russian-speaking users seeking access to blocked services with an aim to intercept browser traffic and route them through a proxy infrastructure. The extensions, published across at least 40 Chrome Web Store developer accounts, racked up 75,486 installs. Of those identified, 274 have been found to impersonate 66

A newly disclosed flaw in the way OpenAI, Anthropic, and Google carried hidden AI reasoning between API calls let researchers recover internal reasoning and secrets from session logs, including API keys and passwords. The weakness affected encrypted reasoning objects used by the providers' reasoning APIs, where a block created in one session could be replayed into another and, during testing,

Enterprise defenses are tuned to catch the attacks that make noise. This year's data shows attackers winning by making none. According to Picus Labs' new Blue Report 2026, which measured more than 338 million real attack simulations across actual client production environments in the first half of 2026, defenses are having one of their strongest years yet. Average prevention effectiveness

Adobe has shipped updates to address multiple critical security vulnerabilities impacting ColdFusion, Commerce, and Campaign Classic that, if successfully exploited, could result in arbitrary code execution and privilege escalation. The most severe of the flaws are listed below - CVE-2026-48362 (CVSS score: 10.0) - An operating system command injection vulnerability in ColdFusion that could

Threat actors have begun to actively exploit a recently patched critical security flaw in Broadcom VMware vCenter, according to new findings from QUIRSO. The vulnerability in question is CVE-2026-59310 (CVSS score: 9.8), a directory-traversal vulnerability in the VMware vCenter server that a malicious actor with network access can exploit to execute arbitrary code. Patches for the flaw were

Two malicious LiteLLM releases sat on PyPI for about 40 minutes in March carrying credential-stealing code capable of harvesting cloud keys, SSH keys, Kubernetes tokens, database passwords, and other secrets from systems that installed them. Threat intelligence firm CloudSEK now says a dataset it obtained, built from roughly 434,000 files the attackers captured, maps potential exposure to more
