More about the "Mail Server Update" scam email

Scammers behind this letter aim to trick recipients into believing that their email service provider has encountered an issue while resolving email server updates that affected their email accounts. They instruct recipients to click the "RESOLVE UPDATE ISSUE" button to resolve the issue (and improve user experience and security and fix bugs).

The "RESOLVE UPDATE ISSUE" button in this email opens a deceptive website (fake login site) designed to extract email addresses and passwords. Scammers use it to steal login credentials.

Similar scam emails in general

Scammers behind phishing emails ask recipients to provide personal information directly via email or a phishing website. They aim to extract credit card details, passwords, ID card information, social security numbers, or other personal information. Usually, they pretend to be legitimate entities (e.g., companies or organizations).

Examples of phishing emails are "Annual Email Version Upgrade Email Scam", "YоuTubе Suppоrt Shared An Item Email Scam", and "FIFTH THIRD BANK Email Scam". Emails can also be used to trick recipients into infecting their computers.

How do spam campaigns infect computers?

Emails used to deliver malware are quite similar to phishing emails. However, they contain malicious links or attachments. Recipients infect computers via those links or files by opening them. Not all files infect computers right after being opened. For example, malicious MS Office documents do not infect computers until users enable macros commands.

Examples of other files that threat actors use to distribute malware are executables, archives (like ZIP and RAR), ISO files, PDF documents, and JavaScript files.

How to avoid installation of malware?

Be careful with emails containing attachments or links. Examine emails before opening their contents (especially when emails are irrelevant and sent from unknown addresses). Avoid downloads from shady pages, third-party downloaders, P2P networks, etc. Download software from reliable sources such as official pages and legitimate stores.

Keep the operating system updated (the same applies to installed programs). Scan your computer for threats regularly. If you've already opened malicious attachments, 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.

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?

The same email was sent to all recipients. It is uncommon for phishing emails to be personal.

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

If you entered your password (and email address) on a phishing page provided in this email, change your passwords as soon as possible. Especially if more than one account can be accessed with the stolen login information.

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

Not all files infect computers after they are opened. For instance, malicious MS Office documents do not infect computers until macros commands are enabled and archives (like ZIP, RAR, etc.) cannot cause harm until malicious files are extracted and executed. However, executables usually infect computers after they are opened. Thus, it depends on the file that was downloaded and opened.

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

It is safe to open emails even when they include malicious attachments or website links.

Will Combo Cleaner remove malware infections that were present in email attachment?

Yes, Combo Cleaner can detect and remove almost all known malware. It is recommended to scan computers using a full scan. High-end malware can be designed to hide deep in the operating system. Thus, running a quick scan is not enough to detect it.
