ENISA: Frontier AI Is Changing the Speed of Cyberattacks. Europe Needs to Catch Up

ENISA warns frontier AI compresses attack lifecycles to minutes, with exploits possible within 15 minutes of disclosure and median 72-minute breach-to-exfiltration times.

ENISA's July 2026 paper 'ENISA's view on Cybersecurity in the Frontier AI Era' argues AI-assisted attackers may weaponize vulnerabilities within 15 minutes of disclosure and achieve initial-access-to-data-exfiltration in a median 72 minutes, creating a 'negative time-to-exploit' problem. The report cites one organisation whose CVE volume rose from roughly 80 in Q1 2025 to almost 500 in Q1 2026, then about 500 reports per day when frontier-AI tools were used. ENISA recommends machine-speed defence under 'Cybersecurity as Code', EPSS and VEX-based prioritisation, AI-assisted incident response with human oversight, and an assume-breached architecture.

Windows memory integrity switches on automatically for eligible devices in October 2026

Microsoft's Windows quality updates will automatically enable memory integrity and Virtualization-based Security on eligible devices starting October 2026.

Beginning in October 2026, Windows quality updates will automatically enable memory integrity on eligible devices and turn on Virtualization-based Security where it is not already running. Memory integrity restricts kernel-mode execution to trusted, signed code and drivers, blocking kernel compromise and rootkits. Microsoft said existing administrator decisions remain in effect, and readiness checks weigh hardware capability, compatibility, and performance. Memory integrity also underpins hotpatch updates that install without a reboot, so unprotected devices are excluded from that servicing model.

CISA tells operators to harden Siemens S7 PLCs. Here’s how to do it without disrupting production

CISA, NSA, FBI and other agencies warn of active targeting of internet-exposed Siemens S7 PLCs and urge patching, exposure removal and hardening.

Joint advisory AA26-231A from the NSA, CISA, FBI, Department of Energy and EPA warns that actors are actively targeting Siemens S7 PLCs using internet scanning, AI-assisted scripts and libraries such as Snap7 and python-snap7 over S7comm on TCP port 102. The advisory covers S7-200 through S7-1500 series controllers and recommends patching, removing internet exposure, access controls, monitoring and disabling unneeded services. Siemens states no new S7 vulnerabilities are involved, only misconfigurations addressed in existing ProductCERT guidance SSB-104599. The article details how to apply each measure without breaking production dependencies such as remote I/O, HMI links and diagnostics.
