Intel Chat with Matt Bromiley and Chris Luft.

Matt and Chris break down four stories from the week in threat intel:

• Cisco CUCM (CVE-2026-20230) — a web-dialer SSRF that chains to root-level RCE, exploited in the wild less than 24 hours after the PoC and full exploit chain were published.

• The latest Ransomware Tool Matrix (RTM) / Ransomware Vulnerability Matrix (RVM) update, profiling three active groups — The Gentlemen, DragonForce and Warlock — and the BYOVD and legit-admin-tool tradecraft they increasingly share.

• Gamaredon's upgraded toolkit against Ukraine (per ESET): new PowerShell downloaders like PteroPaste, Cloudflare tunneling and Workers for C2, and exfiltration to trusted cloud storage such as Amazon S3 and Dropbox.

• Varonis Threat Labs phishing an AI email agent ("Pinchy") — why agents spot technical phishing better than humans yet hand over credentials to a convincing social request, and why you should treat them as privileged junior employees.
