Week in review: Cisco patches exploited email gateway 0-day, Revolut breach
A week-in-review digest covers Cisco's patch for an exploited email gateway zero-day vulnerability and a Revolut data breach in which an attacker impersonating a government agency obtained customer records. The collection also highlights DeepZero, an open-source tool for identifying vulnerable Windows kernel drivers.
Why it matters: Cisco customers running vulnerable email gateways face active exploitation and should apply patches immediately. Revolut customers may need to monitor accounts for fraud given the confirmed unauthorized access to sensitive data. Security teams evaluating driver security should review DeepZero as a hunting capability.
