If your leaked email lookup appears on any of these list of leaked credentials, you’re a potential target for unwanted spam and phishing attacks. Threat actors may also use your email address and other leaked data to take over your accounts, especially if you’ve reused passwords across multiple services. To protect yourself, change your passwords on all sites where your email address has been exposed in data breaches/leaks.
Leaked Email Lookup
This tool checks your email address against several different databases of hacked credentials, including HaveIBeenPwned. It’s fast, simple and free to use.
Recently, a large dataset of Twitter usernames and passwords was published online, according to BleepingComputer. This is the largest set of leaked credentials from a single service that HIBP has ever seen, and it’s likely in wide circulation. This massive leak could make it easy for threat actors to identify Twitter users by their email and phone number.
This is a serious privacy concern, especially for Twitter users who tweet anonymously or have a high follower count, as their real names are likely exposed by this data leak. Twitter has notified users of this leak and is working to verify affected profiles.
Another great free tool for checking if your email is in any of the various data breaches is LeakedEmailChecker, which uses a combination of email analysis and device fingerprinting to detect potential security issues. The site even has an API that you can use to integrate into your website, software or app to perform live checks at the time of account creation and user login.
