NExfil

NExfil is a fast Python-based OSINT tool designed for finding user profiles by username across hundreds of social networks and online platforms. It queries multiple services concurrently to rapidly enumerate where a particular username has been registered, making it a staple in digital footprint assessments and person-of-interest investigations. Penetration testers, OSINT analysts, and law enforcement use NExfil during the reconnaissance phase to map an individual's online presence and identify potential attack surfaces. Its straightforward command-line interface and extensible site list make it easy to integrate into larger investigation pipelines alongside tools like Sherlock and Maigret.
