Ignorant

Ignorant is an OSINT tool that allows you to check if a phone number is used on different platforms like Snapchat, Instagram, and other services. Unlike tools that scrape profiles, Ignorant works by using the password reset and account recovery flows of various services, which typically reveal whether an account exists for a given phone number without notifying the account holder. This makes it a passive reconnaissance tool - the target receives no notification that their phone number was checked. Ignorant is written in Python with a modular architecture that makes it easy to add new platform checks. It's particularly useful during the reconnaissance phase of social engineering assessments, missing person investigations, or when building a profile of a target's digital footprint across services.
