Snusbase
Paid breach-search database indexing leaked credentials and personal data.
Snusbase is a paid database that indexes leaked credentials and personal data from various online breaches. It allows researchers and security professionals to search for compromised information associated with specific email addresses or usernames. This tool is typically used to verify if personal data has been exposed in known data incidents.
Dual-use tool. This is capable of legitimate research (journalism, security, due diligence) and of harassment or stalking. Listing it here is not an endorsement of either use.
Privacy note. Data leaked about you may be indexed here — check and secure affected accounts.
