Interactsh - An OOB Interaction Gathering Server And Client Library

Admin


Interactsh is an Open-Source Solution for Out of band Data Extraction, A tool designed to detect bugs that cause external interactions, For example - Blind SQLi, Blind CMDi, SSRF, etc.


Features
  • DNS/HTTP/SMTP Interaction support
  • CLI Client / Web Dashboard support
  • AES encryption with zero logging
  • Automatic ACME based Wildcard TLS w/ Auto Renewal
  • SELF Hosting version support

A hosted instance of the service with WEB UI is available at https://interact.projectdiscovery.io.

Note: As hosted version doesn't store anything locally, restarting server for maintenance / unexpected server crash / updates will result into loss of previous data.
