Rapid7 introduces credentialed port discovery method

Rapid7 announced a new technique for port scanning called credentialed pre-port discovery. Instead of sending probes to each port, the scan engine uses existing credentials to ask the host directly for a list of open ports, covering both TCP and UDP. This method avoids traditional network probing and can produce more accurate results if credentials are available.

Why it mattersThis approach may improve scan accuracy and speed, especially for hardened or protected hosts where traditional scans struggle. It could also help reveal ports blocked by network controls.

Microsoft releases record number of security patches

Microsoft released updates to fix at least 974 security vulnerabilities across Windows and other products, its largest patch release to date. The update includes critical flaws, some already being exploited, and over 100 rated as dangers that could let attackers seize control of systems. The unprecedented volume is partly due to the use of AI for vulnerability detection, but experts warn that rapid growth complicates efforts to test and deploy fixes.

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.
