## ⚡ Weekly Recap: Chrome 0-Day, UniFi Exploits, macOS Stealers, VPN Flaw and More
Stuff broke again. Not in a movie way. An old tool was left exposed. An abandoned package was abused. A deprecated feature was still running in prod.

Scroll through the full Monday Cybersecurity Recap below for the news, tools, webinars, and fixes worth your time this week.
