By Andy Mulholland - Malware Researcher 10 Min Read

Many sources have reported that numerous users have been receiving an email starting with “I know one of your cards.” Specifically, it is a blackmail in their inbox that the sender claims to know private information about the recipient.

The sender will quickly and directly address the main point. Malware has been installed on a program that the user frequently uses.

While the user was engaged in watching explicit videos, the device began functioning as a remote access device.

The sender was able to gain access to the device, along with the Wi-Fi network and any other connected devices. They claim that the malware was able to transmit various types of data, such as contacts, photos, and videos.

This scam email campaign shares many similarities with another deceptive one, where the threat actor falsely claims to know one of your passwords.

Content of the email

The email mentioned that a malware program has infected your computer, giving the hacker full access and control over different features like the microphone, display, audio, and camera.

Furthermore, the threat actor creates the illusion of having complete access to all aspects of your personal life, including those that the hacker deems extremely confidential.

According to the email, it seems that someone was observed viewing inappropriate content on camera.

They say you may simply forward this unsettling movie to all of your contacts with just a single mouse click. The user will next be blackmailed to transfer $1050 to the hacker's Bitcoin wallet.

Just a heads up before you actually do something, these emails are actually scams or phishing attempts that are sent out to numerous internet users on a daily basis. If you're feeling a bit overwhelmed at the moment, simply take a deep breath and pour yourself a refreshing glass of water.

You can be confident that the information given by the threat actor is completely false, and the whole situation is just a scam. It is important to never send money to con artists under any circumstances.

“I know XXXX is one of your cards” email and scams in general

There have been several fraudulent emails going around online, including one that falsely claims to have information about one of your cards.

We have also come across different versions of this email, like the one that asks, “Isn't XXXX one of your cards?” This version is clearly a rephrased version of the original.

The sender use manipulative tactics to instill fear in the recipient, which makes it more likely for them to be influenced and comply with their demands.

These emails are designed to trick users into providing something in return for concealing information from the public.

The email purports to be from an individual who has gained access to your personal information and accounts. It should be noted that there is currently no evidence provided to support their claims against the recipient.

How these scams trick you into thinking they are real

Wondering how the hacker was able to effortlessly acquire your credit card number, as mentioned in the subject line?

Most likely your card details have been obtained by cybercriminals who discovered them on the dark web. This may have occurred due to a data breach on another website, possibly one where you made a previous purchase.

It's possible that they included your card details in the email to make the attack appear more authentic. However, it could be an old deactivated card from a few years ago that you no longer use.

Summary
Subject lineI know XXX is one of your cards
Threat typePhishing scam, deceptive email, sextortion
Fake claimHackers have gained access to your computer & accounts
Asking amount1200 USD (in Bitcoin)
DamagePotential loss of personal data & money

Now that you have a clear understanding that the email is not genuine, it would be advisable to delete it and move forward, in order to prevent any negative impact on your day.

In addition, running a virus scan on your computer can provide an extra layer of security and peace of mind for those who may be more prone to worry. Stay safe!

Step 3: Use the Tron Script (Optional)

The Tron script fights for the user, therefore it is one of our all-time favorites; it uses practically every removal and optimization method known to man, all with the touch of a single button.

It automates functions and programs for removing malware and bloatware, as well as cleaning up the computer, so the user behind the screen doesn't have to do any work at all.

Fair warning: It has been stated numerous times in the Tron Script documentation that attempting to clean or repair a system that was compromised by malware may result in a disabled PC. As a result, it is recommended that you backup your files before proceeding, as stated at the beginning of the instructions.

With that being said, let us proceed and use the Tron script to clean the system:

1. To start, download the Tron script.

Tron Step1

2. Extract the downloaded Tron file, with the use of an archiver like 7-Zip. Please keep in mind that you will not run the Tron script exactly as it is downloaded. You'll need to extract the.exe first.

Tron Step2

3. After extracting the compressed file, open the Tron folder, right-click the Tron script, and run it as administrator.

Tron Step3

4. The Tron script would have opened up and initialized by updating the database and checking the repo.

Tron Step4

5. Once the initialization is finished, the disclaimer will be shown on the screen. Read it and type I AGREE in all caps to continue.

Tron Step5

6. After agreeing to the disclaimer, it will show your current settings, as well as the Runtime estimate on how long the script may run. Press any key to begin running the Tron script on the system.

Tron Step6

7. It will create a system restore point before beginning the process so if you run into any issues after running the script, you can always restore to the point it created before it started.

Tron Step7

8. Please wait for the whole process to finish. You may see Tron script download and run multiple programs on the computer but it will uninstall them after finishing the process. This might take a long time as shown on the Runtime estimate.

Tron Step8

9. Once everything has finished, the CMD window will have turned green which indicates that the process is a success. Press any key on your keyboard to close the Tron script.

Tron Step9

10. To finalize the Tron script process, we recommend that you restart your computer.

Tron Step10

After restarting your computer, you should no longer see the presence of malware threats. You can always use the Tron script as a last option if you believe your machine is infected and there is no chance of detecting the malware.

Tips to protect your PC from malware

As the saying goes:The biggest vulnerability is the person behind the screen

So, here are some tips and what you need to know in order to keep your device safe and malware-free in the long run.

Keep every software installed up to date

Make sure that all of the programs in your computer is up-to-date with the latest version released by the developer. The reason behind this is that these updates frequently tackle bugs and issues that malware actors often exploit.

The same goes for your computer's operating system, make sure Windows is up-to-date with the latest software update to prevent malware from exploiting a hidden vulnerability.

Avoid downloading files from unknown sources

One of the biggest sources of malware infection in a computer system is third-party installations. This happens when a user downloads a certain program from sources that are not the official download links. Some of the common types of sources where malware is present are torrent files, cracked software, and games.

Be careful with opening email attachments

Malware often disguises itself as resumes and quotations and threat actors often send thousands of these infected emails to company employees around the world in order to infiltrate their network.

Always check where your emails are coming from as there may be a chance that the project attachment you received via email did not actually come from a co-worker.

Do not visit unreputable websites

Avoid visiting websites that contain unfiltered advertisements such as illegal streaming websites, cracked software platforms, and links sent out to you by somebody you do not trust.

These sites are often linked to redirect chains that load once you click on an ad element on the page. Following this chain often leads to drive-by malware and phishing pages that an average user may eventually fail to notice.
