This plugin triggers when an unusual volume of accounts are created from one or multiple IPs in a short period of time.

This may be an early hint that an attacker is trying to reverse engineer your signup mechanism or stacking dormant accounts to be used in a future attack. It could also be an abuse of your service limit (freemium business models).

This plugin is not always synonym of a malicious activity.

Advanced details

Sqreen SDK enables you to track all signup activities happening in your app.

Every minute Sqreen computes the signals and looks for unusual volume of signups.

The signal computation happens on Sqreen’s backend based on the signals collected on all the instances of your applications. This collection happens asynchronously and is not slowing down your app performance.
