Avoid getting scammed by fake "Windows Defender Subscription" emails

Also Known As: Windows Defender Subscription spam email
Damage level: Medium

What kind of email is "Windows Defender Subscription"?

Our analysis of the "Windows Defender Subscription" email revealed that it is spam. This fake letter is presented as a notification regarding the purchase of a one-year subscription for the Windows Defender security software.

It must be emphasized that this is a scam, and it is in no way associated with the Microsoft Defender Antivirus (formerly known as Windows Defender).

Windows Defender Subscription email spam campaign

"Windows Defender Subscription" email scam overview

The scam email with the subject "Order Confirmation" (may vary) presents recipients with the product they ordered - a one-year subscription for "Windows Defender Advanced Threat/ Protection Firewall & Network Protection". The price is listed as 299.99 USD. The spam letter states that if the recipient has not made this purchase or suspects that an unauthorized party made it, they are to call the free helpline.

Evidently, this spam mail aims to trick recipients into calling the provided telephone number; however, how the scam progresses from that point on may vary.

It is likely that the scheme will follow a model similar to refund scams. In these, the victim is informed that the sum has already been subtracted, but the transaction can be reversed. The scammers request users to allow them remote access to their device - in order to aid with the refund process.

Victims are asked to sign into their bank account while the cyber criminals pretend not to see the screen and the entered log-in credentials. Alternatively, the scammers may redirect users to phishing sites that record the log-in credentials.

In the case of the first scenario, once the real bank account is accessed - the victim's screen is blackened while the scammers carry out nefarious actions. The user is usually asked to enter the refund amount themselves (and as they cannot see what they type) are deceived into thinking that they transferred too much money into their account.

The cyber criminals can create this impression by moving funds within the victim's account (e.g., from checking to savings) or by editing the webpage's HTML to appear as though a much larger sum was transferred. The scammers then ask the nonexistent excess to be returned (often accompanied by sob stories about potentially lost jobs).

Cyber criminals request the money to be transferred in difficult or impossible to trace methods, such as cryptocurrencies, gift cards, pre-paid vouchers, or even hidden in innocuous package contents and shipped.

Emails like these "Windows Defender Subscription" letters may also operate as more straightforward phishing scams - in which the victim is asked to provide personally identifiable or finance-related information over the phone or by entering it into a phishing webpage/file.

However, such emails may include more elements of technical support scams. These schemes likewise involve the scammers gaining remote access to the victim's device and then performing fake diagnostics that find imaginary issues. The cyber criminals can then remove genuine security tools, infect the system with malware (e.g., trojans, ransomware, etc.), deceive victims into purchasing fake anti-viruses or security subscriptions, and so on.

It is noteworthy that successfully scammed victims are commonly targeted repeatedly. In summary, by trusting scams like the "Windows Defender Subscription" emails - users can experience system infections, severe privacy issues, significant financial losses, and even identity theft.

Spam campaign examples

We have analyzed thousands of spam emails; "Login Session Authentication", "Webmail Manager email scam", "FedEx Corporation email virus", "Summon To Court For Pedophilia", "I Regret To Inform You About Some Sad News For You" - are merely some examples of our latest finds.

These letters are used to carry out a wide variety of scams and also to proliferate malware. This mail can make various claims and wear different disguises. Due to how widespread spam mail is, we strongly advise exercising caution with incoming emails and messages.

How do spam campaigns infect computers?

Spam emails can distribute infectious files in the form of attachments or download links. These files can be PDF and Microsoft Office documents, archives, executables, JavaScript, and so forth.

When a virulent file is executed, run, or otherwise opened - the infection chain is jumpstarted. For example, Microsoft Office documents infect systems by executing malicious macro commands.

How to avoid installation of malware?

We highly recommend being vigilant with incoming mail. The attachments and links found in dubious/irrelevant emails and messages - must not be opened since that can result in a system infection. Additionally, it is important to use Microsoft Office versions released after 2010, as they have the "Protected View" mode that prevents macros from being executed automatically.

However, malware is not distributed exclusively via spam mail. Therefore, we advise downloading only from official/verified sources and activating/updating software with legitimate tools (as illegal activation tools - "cracks" and fake updates may contain malware).

We must stress that having a reputable anti-virus installed and kept updated is essential to device/user safety. Security programs must be used to run regular system scans and to remove threats and issues. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Types of malicious emails:

Phishing email icon Phishing Emails

Most commonly, cybercriminals use deceptive emails to trick Internet users into giving away their sensitive private information, for example, login information for various online services, email accounts, or online banking information.

Such attacks are called phishing. In a phishing attack, cybercriminals usually send an email message with some popular service logo (for example, Microsoft, DHL, Amazon, Netflix), create urgency (wrong shipping address, expired password, etc.), and place a link which they hope their potential victims will click on.

After clicking the link presented in such email message, victims are redirected to a fake website that looks identical or extremely similar to the original one. Victims are then asked to enter their password, credit card details, or some other information that gets stolen by cybercriminals.

Email-virus icon Emails with Malicious Attachments

Another popular attack vector is email spam with malicious attachments that infect users' computers with malware. Malicious attachments usually carry trojans that are capable of stealing passwords, banking information, and other sensitive information.

In such attacks, cybercriminals' main goal is to trick their potential victims into opening an infected email attachment. To achieve this goal, email messages usually talk about recently received invoices, faxes, or voice messages.

If a potential victim falls for the lure and opens the attachment, their computers get infected, and cybercriminals can collect a lot of sensitive information.

While it's a more complicated method to steal personal information (spam filters and antivirus programs usually detect such attempts), if successful, cybercriminals can get a much wider array of data and can collect information for a long period of time.

Sextortion email icon Sextortion Emails

This is a type of phishing. In this case, users receive an email claiming that a cybercriminal could access the webcam of the potential victim and has a video recording of one's masturbation.

To get rid of the video, victims are asked to pay a ransom (usually using Bitcoin or another cryptocurrency). Nevertheless, all of these claims are false - users who receive such emails should ignore and delete them.

How to spot a malicious email?

While cyber criminals try to make their lure emails look trustworthy, here are some things that you should look for when trying to spot a phishing email:

  • Check the sender's ("from") email address: Hover your mouse over the "from" address and check if it's legitimate. For example, if you received an email from Microsoft, be sure to check if the email address is @microsoft.com and not something suspicious like @m1crosoft.com, @microsfot.com, @account-security-noreply.com, etc.
  • Check for generic greetings: If the greeting in the email is "Dear user", "Dear @youremail.com", "Dear valued customer", this should raise suspiciousness. Most commonly, companies call you by your name. Lack of this information could signal a phishing attempt.
  • Check the links in the email: Hover your mouse over the link presented in the email, if the link that appears seems suspicious, don't click it. For example, if you received an email from Microsoft and the link in the email shows that it will go to firebasestorage.googleapis.com/v0... you shouldn't trust it. It's best not to click any links in the emails but to visit the company website that sent you the email in the first place.
  • Don't blindly trust email attachments: Most commonly, legitimate companies will ask you to log in to their website and to view any documents there; if you received an email with an attachment, it's a good idea to scan it with an antivirus application. Infected email attachments are a common attack vector used by cybercriminals.

To minimise the risk of opening phishing and malicious emails we recommend using Combo Cleaner Antivirus for Windows

What to do if you fell for an email scam?

  • If you clicked on a link in a phishing email and entered your password - be sure to change your password as soon as possible. Usually, cybercriminals collect stolen credentials and then sell them to other groups that use them for malicious purposes. If you change your password in a timely manner, there's a chance that criminals won't have enough time to do any damage.
  • If you entered your credit card information - contact your bank as soon as possible and explain the situation. There's a good chance that you will need to cancel your compromised credit card and get a new one.
  • If you see any signs of identity theft - you should immediately contact the Federal Trade Commission. This institution will collect information about your situation and create a personal recovery plan.
  • If you opened a malicious attachment - your computer is probably infected, you should scan it with a reputable antivirus application. For this purpose, we recommend using Combo Cleaner Antivirus for Windows.
  • Help other Internet users - report phishing emails to Anti-Phishing Working Group, FBI’s Internet Crime Complaint Center, National Fraud Information Center and U.S. Department of Justice.

Frequently Asked Questions (FAQ)

Why did I receive this email?

Spam emails are not personal. Thousands of users receive identical letters.

I have provided my personal information when tricked by this spam email, what should I do?

If you have disclosed log-in credentials - change the passwords of all potentially compromised accounts and inform their official support. And if the exposed information is of a different personal nature (e.g., ID card details, credit card numbers, etc.) - contact the corresponding authorities without delay.

I have allowed cyber criminals to remotely access my computer, what should I do?

If you have permitted cyber criminals to remotely access your device, you must first disconnect it from the Internet. Afterward, remove the software the criminals used (e.g., TeamViewer, AnyDesk, etc.), as they may not need your consent to re-access your computer. Lastly, perform a full system scan. If any threats are detected - use an anti-virus to remove them without delay.

I have read a spam email but didn't open the attachment, is my computer infected?

No, merely reading a spam email will not result in a system infection. Malware download/installation processes are triggered when the files attached to or linked inside these letters are opened. However, the cyber criminals behind this mail can also infect victims' computers if they are allowed to access them remotely.

I have downloaded and opened a file attached to a spam email, is my computer infected?

If it was an executable (.exe, .run, etc.) - most likely, yes - your system was infected. However, document formats (.doc, .xls, .pdf, etc.) may require additional actions (e.g., enabling macro commands) to begin downloading/installing malware.

Will Combo Cleaner remove malware infections?

Yes, Combo Cleaner is designed to detect and remove threats. It is capable of eliminating most of the all known malware infections. However, it is essential to perform a complete system scan - since sophisticated malicious software tends to hide deep within systems.
