‘Website Customer Invoice’ Malware Email Scam [Explained]

Scams have become increasingly sophisticated in the digital age, with cybercriminals constantly finding new ways to exploit unsuspecting individuals. One such scam that has gained traction in recent years is the ‘Website Customer Invoice’ malware email scam. This article aims to provide a comprehensive overview of this scam, including what it is, how it works, what to do if you have fallen victim, and other relevant data.


What is the ‘Website Customer Invoice’ Malware Email Scam?

The ‘Website Customer Invoice’ malware email scam is a type of phishing attack that targets individuals who own or manage websites. The scam typically involves sending an email that appears to be a legitimate invoice from a customer who has made a purchase on the website. The email often includes a link or attachment that, when clicked or opened, installs malware onto the recipient’s computer.

How Does the Scam Work?

The ‘Website Customer Invoice’ malware email scam relies on social engineering techniques to trick recipients into taking action. Here is a step-by-step breakdown of how the scam typically unfolds:

  1. The scammer identifies a target by obtaining their email address from publicly available sources or through data breaches.
  2. The scammer crafts an email that appears to be from a legitimate customer who has made a purchase on the target’s website.
  3. The email includes details such as the customer’s name, order number, and a seemingly genuine invoice.
  4. To create a sense of urgency, the email may claim that the invoice is overdue or that the customer’s account will be suspended if payment is not made immediately.
  5. The email contains a link or attachment that the recipient is instructed to click or open to view the invoice or make a payment.
  6. Clicking the link or opening the attachment triggers the installation of malware onto the recipient’s computer.
  7. Once installed, the malware can perform various malicious activities, such as stealing sensitive information, logging keystrokes, or encrypting files for ransom.

What to Do If You Have Fallen Victim

If you have fallen victim to the ‘Website Customer Invoice’ malware email scam, it is crucial to take immediate action to minimize the potential damage. Here are the steps you should follow:

  1. Disconnect from the internet: Unplug your computer from the network to prevent the malware from communicating with the attacker.
  2. Scan for malware: Run a scan with a reputable antivirus or anti-malware software, such as Malwarebytes Free, to detect and remove any malicious software.
  3. Change passwords: Change the passwords for all your online accounts, especially those related to your website, email, and financial accounts.
  4. Monitor accounts: Keep a close eye on your bank and credit card statements for any unauthorized transactions. Report any suspicious activity to your financial institution immediately.
  5. Inform others: If you received the scam email from a customer’s compromised account, notify them about the incident so they can take appropriate action.
  6. Report the scam: File a complaint with your local law enforcement agency and report the scam to the appropriate authorities, such as the Federal Trade Commission (FTC) in the United States.

How to Stay Safe Online

Here are 10 basic security tips to help you avoid malware and protect your device:

  1. 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.

  2. 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.

  3. 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."

  4. Install an ad blocker.

    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.

  5. 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.

  6. 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.

  7. 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.

  8. 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.

  9. Be careful where you click.
