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.
- 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.
