Cyber threats are no longer coming from just malware or exploits. They’re showing up inside the tools, platforms, and ecosystems organizations use every day. As companies connect AI, cloud apps, developer tools, and communication systems, attackers are following those same paths. A clear pattern this week: attackers are abusing trust. Trusted updates, trusted marketplaces, trusted apps, evenView the full article

Why do SOC teams keep burning out and missing SLAs even after spending big on security tools? Routine triage piles up, senior specialists get dragged into basic validation, and MTTR climbs, while stealthy threats still find room to slip through. Top CISOs have realized the solution isn’t hiring more people or stacking yet another tool onto the workflow, but giving their teams faster, clearerView the full article

This week didn’t produce one big headline. It produced many small signals — the kind that quietly shape what attacks will look like next. Researchers tracked intrusions that start in ordinary places: developer workflows, remote tools, cloud access, identity paths, and even routine user actions. Nothing looked dramatic on the surface. That’s the point. Entry is becoming lessView the full article

Today’s “AI everywhere” reality is woven into everyday workflows across the enterprise, embedded in SaaS platforms, browsers, copilots, extensions, and a rapidly expanding universe of shadow tools that appear faster than security teams can track. Yet most organizations still rely on legacy controls that operate far away from where AI interactions actually occur. The result is a wideningView the full article
