Holehe: Check Email Compromise

Open source tool to check if email addresses have been compromised in data breaches, searching through publicly available data breach databases.

What is Holehe?

Holehe is an open source command line tool used to check if email addresses or domains have been compromised in known data breaches. It searches through public databases of breached data, compiled from various leaked password dumps and data breaches over the years.

To use Holehe, you enter an email address or domain name as input. Behind the scenes, it searches through databases like HIBP, BreachCompilation, and more. If the email address is found in any leaks, Holehe will output details on the breaches, including source, date, and number of compromised accounts. This helps you know if any credentials associated with that address may be exposed.

As an open source tool, Holehe is freely available to use. It runs on Python and works across Windows, Mac, and Linux. Key features include checking individual email addresses, entire domains, speed optimized searching, and data from over 10 billion leaked credentials. Overall it serves as a handy way to monitor if your own accounts have been caught up in major data breaches.
