Today’s threats highlight: exploit floods, mis‑trusted infrastructure, and phishing evolving into new channels.

Google patched two critical V8 engine flaws (including CVE‑2025‑13223) already being exploited. 

Why it matters: When the browser core is under attack, your entire endpoint fleet is vulnerable—from dev machines to exec laptops.

Question: When was the last time your org ran a browser‑baseline check across non‑IT assets (contractors, lab machines, kiosks)?

🛡️ 2. Fortinet Confirms Active Exploitation of Critical FortiWeb WAF Vulnerability

Specifically CVE‑2025‑64446 allows unauthenticated attackers to execute admin commands on the FortiWeb appliance. 

Why it matters: A compromised WAF = attacker inside the network with filtering turned off, invisibility, persistence.

Probe: How quickly could you detect a WAF appliance doing admin operations you didn’t authorise?

This campaign uses the ‘ClickFix’ social‑engineering methodology to drop the Amatera Stealer and NetSupport RAT. 

Why it matters: Phishing is evolving fast — not just email links, but scripted user actions and malware packaged as utility fixes.

Takeaway: Even well‑trained users can be tricked if the path looks like “fix my system” and uses trusted tools.

https://thehackernews.com/2025/11/5-reasons-why-attackers-are-phishing.html

This piece breaks down why professional networks (LinkedIn) are being targeted for phishing campaigns — 1 in 3 attacks now happen outside email. 

Why it matters: Your social presence, even personal accounts tied to your professional life, can be pivot points.

Reflection: When did you last review the phishing exposure via your org’s social media + employee profiles?

🔍 Summary

Theme: Attackers are striking where you least expect — browser engines, WAFs, social/utility phishing.

Takeaway: Defense isn’t just about “patches” or “training” anymore — it’s about holistic vigilance: endpoints, infrastructure, social channels.

Action Step: Pick one: browser‑baseline refresh, WAF activity review, phishing simulation via non‑email, or social profile audit — and schedule it this week.
