GlassWire Alert Dictionary

A list of GlassWire alert icons along with a description of what they represent.

Evil twin

WiFi Evil Twin Alert
Know when new hardware comes online that uses the same WiFi network name you’re currently using. This feature helps you avoid “evil twin” attacks where a separate new WiFi network is made to trick you or your colleagues into connecting to it to monitor your network activity illegally or exploit your device. This alert also tells you when your WiFi network loses its password.

Application monitor

New Application Monitor
Alerts you every time a new unknown application is accessing the Internet or network. Initially you may receive a lot of these alerts immediately after installing GlassWire but they will become rare over time. These alerts are useful because you can see when any new application on your system is suddenly accessing the Internet and investigate the details. It's interesting to see what applications phone home to unknown servers or do things you never expected on the network.

File changed

System File Changed
Alerts you to a system file that has changed that is network related. If a network related file is modified it may be a good idea to check it out if you didn't initiate the change yourself.

Driver changed

Alerts you to any network related devices on your system that were changed.

App info changed
