The “I Know That You Cheat On Your Partner” Email Scam
Written by: Stelian Pilici
Published on:
The “I Know That You Cheat On Your Partner” email is a scam that tries to trick you into thinking that your computer or phone is infected with malware and then threatens to make your data public. Contrary to the claims in the email, you haven’t been hacked (or at least, that’s not what prompted this email) and this is nothing more than a scam that tries to trick you into sending Bitcoins to these scammers. This is merely a new variation on an old scam which is popularly being called “sextortion”.
This is the text of the “I Know That You Cheat On Your Partner” blackmail email, including the grammatical and spelling errors:
Subject: New payment !
Hello
For some time now, I have been watching you
I know that you cheat on your partner.Its not my business, but i could make you loose everything if you fail to follow my instructions
All you have to do to prevent this from happening is – transfer bitcoins worth $580 (USD) to my Bitcoin address (if you have no idea how to do this, you can open your browser and simply search: “Buy Bitcoin”).
My bitcoin addresses (USE ANY OF THE BTC Wallets) :
BTC : bc1quv2l07cec2pluq6qgpv95fu990mjlm7ljqksky
BTC: bc1q444vm07qcwqyd3ytrnmp2hyklc3kq97qlvgvxl
After receiving a confirmation of your payment, I will delete the video right away, and that’s it, you will never hear from me again.
You have 2 days (48 hours) to complete this transaction.
Once you open this e-mail, I will receive a notification, and my timer will start ticking.
Any attempt to file a complaint will not result in anything, since this e-mail cannot be traced back, same as my bitcoin id.
I have been working on this for a very long time by now; I do not give any chance for a mistake.
If, by any chance I find out that you have shared this message with anybody else, I will broadcast your video as mentioned above.
The above email and anything it states is just a scam to try and scare you into paying the ransom. If you have received the “I Know That You Cheat On Your Partner” email, we recommend deleting it and under no circumstances sending any money to these cybercriminals.

Is the “I Know That You Cheat On Your Partner” email real?
No, and don’t panic. The “I Know That You Cheat On Your Partner” email is a scam that tries to trick you into thinking that your device or email has been hacked, then demands payment, or else they will send compromising information -such as images of you captured through your web camera or your pornographic browsing history – to all your friends and family. And in classic ransomware fashion, there’s typically a ticking clock. Giving users a short time limit to deliver the payment is social engineering at its finest.
Threats, intimidation, and high-pressure tactics are classic signs of a scam.
As you can imagine, the “I Know That You Cheat On Your Partner” extortion email and anything it states is just a scam to try and scare you into paying the ransom.
They have my password! How did they get my password?
To make the threats more credible, the scammers may include one of your passwords in this email. The scammers have your password from sites that were hacked, and in this case, likely matched up to a database of emails and stolen passwords and sent this scam out to potentially millions of people. You can check if your email or password was compromised in a data breach on Haveibeenpwned.
If the password emailed to you is one that you still use, in any context whatsoever, stop using it and change it NOW. It’s also recommended that you enable two-factor authentication for your email and online accounts whenever that is an option.
Should I pay the ransom?
You should not pay the ransom. If you pay the ransom, you’re not only losing money but you’re encouraging the scammers to continue phishing other people.
Delete the “I Know That You Cheat On Your Partner” email, and under no circumstances pay these cybercriminals a penny/dime/bitcoin.

How to Stay Safe Online
Here are 10 basic security tips to help you avoid malware and protect your device:
Use a good antivirus and keep it up-to-date.
It's essential to use a good quality antivirus and keep it up-to-date to stay ahead of the latest cyber threats. We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.
Keep software and operating systems up-to-date.
Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.
Be careful when installing programs and apps.
Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."
Install an ad blocker.
Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.
Be careful what you download.
A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.
Be alert for people trying to trick you.
Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.
Back up your data.
Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.
Choose strong passwords.
Use strong and unique passwords for each of your accounts. Avoid using personal information or easily guessable words in your passwords. Enable two-factor authentication (2FA) on your accounts whenever possible.
Be careful where you click.
Be cautious when clicking on links or downloading attachments from unknown sources. These could potentially contain malware or phishing scams.
Don't use pirated software.
Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.
To avoid potential dangers on the internet, it's important to follow these 10 basic safety rules. By doing so, you can protect yourself from many of the unpleasant surprises that can arise when using the web.
