I.T. Support ‘Mail Server Upgrade’ Phishing Scam [Explained]

Scammers are constantly coming up with new ways to deceive unsuspecting individuals and steal their personal information. One such scam that has been on the rise is the I.T. Support ‘Mail Server Upgrade’ phishing scam. This article aims to provide valuable insights into this scam, including what it is, how it works, what to do if you have fallen victim, and other relevant data.


What is the I.T. Support ‘Mail Server Upgrade’ Phishing Scam?

The I.T. Support ‘Mail Server Upgrade’ phishing scam is a type of cyber attack where scammers impersonate I.T. support personnel and send fraudulent emails to unsuspecting individuals. These emails typically claim that there is a need to upgrade the mail server and request the recipient to provide their login credentials or other sensitive information.

How Does the Scam Work?

The scam starts with the scammers sending out mass emails to a large number of individuals. These emails are designed to look like legitimate communication from the I.T. department of a company or organization. The email usually contains a message stating that there is a need to upgrade the mail server to improve security or enhance functionality.

To make the email appear more convincing, scammers often use the company’s logo, email signature, and other elements that mimic the organization’s branding. They may also include a sense of urgency, stating that failure to provide the requested information within a certain timeframe will result in account suspension or loss of access to important emails.

Once the recipient falls for the scam and provides their login credentials or other sensitive information, the scammers gain unauthorized access to their email account. They can then use this access to carry out various malicious activities, such as sending spam emails, stealing personal information, or even conducting further phishing attacks on the victim’s contacts.

What to Do If You Have Fallen Victim?

If you have fallen victim to the I.T. Support ‘Mail Server Upgrade’ phishing scam, it is crucial to take immediate action to minimize the potential damage. Here are the steps you should follow:

  1. Change your email account password: As soon as you realize that you have been scammed, change your email account password to prevent further unauthorized access.
  2. Scan your device for malware: Run a scan with Malwarebytes Free or any reputable antivirus software to check for any malware that may have been installed on your device.
  3. Enable two-factor authentication: Enable two-factor authentication for your email account to add an extra layer of security. This will require you to provide a second form of verification, such as a code sent to your phone, in addition to your password.
  4. Check for unauthorized activity: Review your email account for any unauthorized activity, such as unfamiliar emails sent from your account or changes to your account settings.
  5. Report the scam: Report the phishing scam to your email service provider and any relevant authorities, such as the local police or the Federal Trade Commission (FTC).

Other Relevant Data

According to a report by the Anti-Phishing Working Group (APWG), phishing attacks have been on the rise in recent years, with a significant increase in the number of attacks targeting email users. In 2022 alone, there were over 2 million reported phishing attacks, resulting in billions of dollars in financial losses.

It is important to note that scammers are constantly evolving their tactics to make their phishing emails more convincing. They may use advanced techniques such as email spoofing, where they manipulate the email headers to make it appear as if the email is coming from a legitimate source.

To protect yourself from falling victim to phishing scams, it is essential to be vigilant and follow best practices, such as:

  • Double-checking the sender’s email address: Pay close attention to the email address of the sender and look for any suspicious or misspelled domain names.
  • Avoiding clicking on suspicious links: Hover over links in emails to see the actual URL before clicking on them. If the URL looks suspicious or unfamiliar, do not click on it.
  • Verifying requests for sensitive information: If you receive an email requesting sensitive information, such as login credentials or financial details, contact the sender through a separate channel to verify the request.
  • Keeping your software up to date: Regularly update your operating system, web browser, and antivirus software to ensure you have the latest security patches.

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.

    backup sign

    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.

    Be cautious when clicking on links or downloading attachments from unknown sources. These could potentially contain malware or phishing scams.

  10. 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.
