EU sets 24-hour bug reporting rule for software vendors

Starting September 11, 2026, manufacturers selling software or connected devices in the EU must report any actively exploited product vulnerabilities within 24 hours of learning of them, under the Cyber Resilience Act. The initial notice is to be followed by a fuller notification in 72 hours and a final report after any mitigation. Continuous detection of active threats is advised to meet this deadline.

Why it mattersThis rule requires organizations to rapidly detect and report software vulnerabilities, raising the bar for cybersecurity across products sold in Europe. Businesses may need to change their monitoring and incident response processes to comply.

Google warns of rising attacks on enterprise AI assets

Google Cloud's security team reports that attackers are increasingly targeting enterprise AI systems, including proprietary models, source code, and cloud resources. Threat actors have shifted from using basic AI prompts to deploying automated, multi-agent AI workflows that can execute breaches rapidly, sometimes in under six hours. The report highlights incidents of mass credential theft and the compromise of cloud infrastructure to run unauthorized AI workloads.
