Hello. By pairing AI with their industry expertise, bug hunters are targeting fewer, but higher-prized security flaws that promise a bigger payday.

Human insight remains critical to steering AI models to find deeper, novel vulnerabilities—“things that people have never seen before,” as Dave Gerry, Bugcrowd’s chief executive, puts it. Read our full story.

Reduce Cyber Risk as AI Exposes Vulnerabilities

The recent “Claude Mythos” model is a reminder of what happens when frontier models can discover and exploit vulnerabilities at machine speed. Threat actors aren’t just using AI for better phishing anymore; they’re industrializing the entire attack lifecycle. In this special webinar, Zscaler CEO Jay Chaudhry and security executives share practical advice to reduce exposure and stay ahead.

About 1.8 million people were affected by a hack at a major New York health system that went on for nearly three months starting in November. NYC Health + Hospitals reported the tally to the U.S. Department of Health and Human Services after disclosing the incident in February. Clinical, insurance, financial, biometric and geolocation information was breached, the health system said. (TechCrunch)

U.K. car dealership Vertu Motors said insurance largely insulated it from a financial hit related to the cyberattack at Jaguar Land Rover. The August hack led to five weeks of factory downtime at the car maker. Jaguar's lack of production decreased Vertu's profits by about £3.9 million, or $5.2 million, in its most recent fiscal year, CFO Karen Anderson told financial analysts Monday. Vertu, one of the biggest dealership chains in the U.K., received £3.4 million from insurance, CEO Robert Forrester said.
