How do the tools work to check if there is a data breach?

Currently, there are a large number of tools to check if your email has been filtered, both recent and old leaks. The different tools use the leaked databases to check if your email is in them, and if they are, it will notify you that a data leak has occurred.

Use this tool to see if your email has been hacked

Fortunately, determining whether or not your email has been hacked does not require any special skills. There are web pages that, for example, evaluate if an email account has been compromised based on botnet or data leak analyses. 

Botnets are infected computer networks that are frequently utilized for illegal activities without the users’ awareness. Typically, the bot software is placed on the victim’s PC via phishing emails. The Internet Security Office, for example, provides up-to-date information about this type of network, as well as updates on Trojans, spam, secure passwords, and other topics.

Have I Been Pwned? (HIBP) is a website that allows you to check if your email address has been hacked. The term “pwned” comes from the Internet slang and the gaming community, and refers to the word “owned.” Now, beyond the name of the tool, the functionality developed by Troy Hunt, a web security specialist, allows users to enter and verify whether or not their electronic mail has been hacked.

It offers a Notify me notification option that will notify you if your email address or username appears in any of the data leaks at any moment. To do so, simply enter your email address and complete a problem that is part of the security procedure (known as Captcha). This final step is taken to rule out the possibility that it is a robot and that you are a real person, ensuring that the service is better protected.

These are comprehensive services that typically provide applications for a variety of platforms and can be free or paid depending on the features you require. And it’s because, in addition to saving your passwords, they also educate you on how to handle and care for them.

Third-party password managers may also feature a mechanism for creating strong passwords automatically and randomly, as well as warnings that notify you when you have weak or overly repetitive passwords across different sites.
