Buster is an open source OSINT tool designed for email reconnaissance and information gathering. It helps investigators, security researchers, and penetration testers discover publicly available information related to email addresses and usernames. It can analyze an email address to identify associated social media accounts, references across the web, and potential data breaches linked to that email. It also performs reverse WHOIS lookups to discover domains that may have been registered using a specific email address. In addition to investigating existing addresses, Buster can generate possible email combinations and usernames based on personal details such as a person’s name, birthdate, or additional hints. Buster supports validating generated email addresses and retrieving contextual information about them. By combining multiple online sources and services, Buster helps automate the process of gathering intelligence related to digital identities.
