You might be. It’s the way some of the cleverest forms of malware spread by hijacking your email address to do their dirty work. Luckily, there’s an easy way to check whether your email or domain has been used behind your back.

Is your email address spamming people?

The Emotet botnet is one of the most effective email malware campaigns around. It started as a banking Trojan and now spreads primarily through phishing emails that lead the recipient to a malicious URL. If there’s a spam operation using your email address, there’s a good chance it’s this one. The Russian cybercrime operation uses sophisticated tactics like replying to an old email thread to look more believable. To know if Emotet is working behind the scenes using your account, I found a free tool you can use: haveIbeenEMOTET. A quick note in case you’re thinking, “Hey, that sounds familiar.” The site name may sound similar to HaveIBeenPwned, but there’s no affiliation. HaveIBeenPwned is another excellent free tool that tells you whether your data has been exposed in a data breach or sold on the Dark Web. Tap or click here to listen to my podcast with the site’s creator, Troy Hunt. He operates the web’s biggest database of hacked logins.

Here’s how to check

Once you visit haveIbeenEMOTET, give your email address or domain name site and hit enter. You’ll get one of a few results: Confirmation that your email address has not been used in an Emotet spam campaign or verification that it has. If your email address or domain has been used, it will be marked as either “Sender Fake,” “Sender Real” or “Recipient.” If you get one of the latter results, you need to take steps to repair the possible damage.

The haveIbeenEMOTET site doesn’t retain any information about your email address or domain that you input. It simply checks your info against data it has in its database.
