5 Places where Mature SOCs Keep MTTR Fast and Others Waste Time https://thehackernews.com/2026/04/5-places-where-mature-socs-keep-mttr.html Security teams often present MTTR as an internal KPI. Leadership sees it differently: every hour a threat dwells inside the environment is an hour of potential data exfiltration, service disruption, regulatory exposure, and brand damage.  The root cause of slow MTTR is almost never "not enough analysts." It is almost always the same structural problem: threat intelligence that exists

No Exploit Needed: How Attackers Walk Through the Front Door via Identity-Based Attacks https://thehackernews.com/2026/04/no-exploit-needed-how-attackers-walk.html The cybersecurity industry has spent the last several years chasing sophisticated threats like zero-days, supply chain compromises, and AI-generated exploits.

⚡ Weekly Recap: Vercel Hack, Push Fraud, QEMU Abused, New Android RATs Emerge & More https://thehackernews.com/2026/04/weekly-recap-vercel-hack-push-fraud.html Monday’s recap shows the same pattern in different places. A third-party tool becomes a way in, then leads to internal access. A trusted download path is briefly swapped to deliver malware. Browser extensions act normally while pulling data and running code. Even update channels are used to push payloads. It’s not breaking systems—it’s bending trust. There’s also a shift in how attacks run.

Why Most AI Deployments Stall After the Demo https://thehackernews.com/2026/04/why-most-ai-deployments-stall-after-demo.html The fastest way to fall in love with an AI tool is to watch the demo. Everything moves quickly. Prompts land cleanly. The system produces impressive outputs in seconds. It feels like the beginning of a new era for your team. But most AI initiatives don't fail because of bad technology. They stall because what worked in the demo doesn't survive contact with real operations. The gap between a
