Cisco SD-WAN Bug Actively Exploited

Cisco SD-WAN Bug Actively Exploited, MCP Azure Takeover Demo, CarGurus Data Leak, and Secret Service Scam Recovery

Host Jim Love covers four cybersecurity stories: CSA warns a critical Cisco Catalyst SD-WAN controller vulnerability (CVE-2026-20127) has been exploited since 2023, enabling authentication bypass and rogue peering sessions, and orders U.S. federal agencies to inventory systems, collect logs and forensic artifacts, hunt for compromise, and apply Cisco’s fixes by 5:00 PM ET on February 27, 2026, with no workarounds. At RSA, researchers show how flaws in Model Context Protocol (MCP)—a key integration layer for agentic AI—could lead to remote code execution and even Azure tenant takeover, highlighting rising enterprise risk. ShinyHunters reportedly published 12.4 million stolen CarGurus records, raising phishing and fraud concerns tied to vehicle shopping and financing context. Finally, an Ontario tech support scam victim recovers funds through coordinated work by Ontario Provincial Police and the U.S. Secret Service, which traced and froze the money in time.
