Checked October 2026.

## What is Ensnare?

Ensnare is a Ruby on Rails gem plugin designed to detect and respond to malicious behavior in web applications.

The tool implements a combination of honey traps that are designed to entice malicious users into revealing their intentions. When triggered, these traps activate a configurable suite of responses aimed at confusing, misleading, delaying, or stopping attackers.

Ensnare integrates directly into Rails applications through a gem installation process. The setup involves adding the gem to a project's Gemfile, running database migrations, and configuring the application controller to enable the detection mechanisms.

The tool requires enabling parameter tampering detection by modifying the mass assignment sanitizer configuration and adding a before filter to the application controller. Once configured, Ensnare mounts its engine to provide monitoring and response capabilities.

The detection system operates by monitoring for suspicious activities and parameter manipulation attempts. When malicious behavior is identified, the configured trap responses are activated to interfere with the attacker's activities.
