I Know You Are Cheating On Your Partner is a blackmail e-mail, sent out to deceive you into thinking the hacker knows your “cheating”. In the content of the e-mail your password is included, which is odd as to why and how would a hacker know your password? Well, this is most likely due to a recent hack or data breach on a website where hackers collected many passwords.
What they do, these hackers sent out fake e-mails with a false message and include one of the passwords they hacked in the e-mail, making it look legit and real to the victim. You can find out if your e-mail is compromised during a hack at haveibeenpwned.com.
After the victim has received the fake e-mail the e-mail contains a bitcoin address to pay ransom for a fake crime or fake message such as: I Know You Are Cheating On Your Partner
Some information in the mail varies in different examples of the mail and if the attack is successful it may evolve more over time. At the time of writing, the sender’s email address (either in the reply-to field or in one case included, in the text of the mail), the ransom amount, and the bitcoin address all vary.
No need to panic, all you have to do is to check if the e-mail containing the password matches the password you are using now if so, change it immediately, it not, it is an old password and I only advise you to scan your computer for malware.
- Always use unique passwords, as some websites or services might get hacked soon or later, which can result in hackers gathering passwords and use these passwords on a variety of services to see if they still work.
- Use a password manager to store your passwords securely.
- Never pay the ransom asked for in the e-mail to the hackers.
