Cybersecurity Intelligence Briefing — November 15, 2024
CISA's November 2024 Known Exploited Vulnerabilities bulletin and the UK NCSC Annual Review expose persistent exploitation patterns boards must address.
Executive briefing: CISA expanded the Known Exploited Vulnerabilities (KEV) Catalog on November 14, 2024 with 12 actively exploited flaws spanning Ivanti, Atlassian, Cisco, and Microsoft products and set remediation deadlines for U.S. federal agencies. The UK National Cyber Security Centre’s Annual Review 2024 (published November 6, 2024) details a 64% year-over-year increase in ransomware incidents affecting UK critical infrastructure and emphasises supply-chain compromise trends.
Key industry signals
- Mandatory patch clocks. CISA requires federal agencies to remediate the new KEV entries by December 5, 2024, providing a de facto deadline for commercial operators.
- Ransomware escalation. NCSC reports 2,005 ransomware referrals in FY2023/24, with double-extortion tactics dominating.
- Supply-chain exposure. Both agencies highlight managed file transfer platforms and MSP tooling as recurring intrusion vectors.
Control alignment
- NIST CSF 2.0. Prioritise Detect and Respond outcomes by monitoring asset inventories against KEV identifiers and rehearsing incident response for ransomware playbooks.
- CIS Critical Security Controls. Implement Control 7 (Continuous Vulnerability Management) and Control 15 (Service Provider Management) to mitigate highlighted risks.
Detection and response priorities
- Correlate KEV CVEs with SOC telemetry—focus on edge devices, VPN gateways, and collaboration platforms referenced in the bulletin.
- Adopt NCSC’s joint advisories for ransomware response, including secure offline backups, credential rotation, and law-enforcement notification flows.
Enablement moves
- Brief executives on the KEV remediation timelines and NCSC ransomware statistics to reinforce budget for patch management and supplier assurance.
- Update supplier questionnaires to confirm MSPs are tracking KEV entries and aligning with NCSC’s Cyber Assessment Framework.
