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
