More about the "Mail Cloud Server" scam email

This phishing email "informs" the recipient that their password will expire on 10/03/2025 (the date may vary) and urges them to take action to keep their credentials unchanged. The email instructs the recipient to use the provided link ("Keep Same Password") to keep the same password. It also claims to be from the administrator of the recipient's email account.

During our examination of the email, the website presented in it was down. However, it is highly likely that the site was intended to mimic a legitimate email account login page. The purpose of such sites is to steal email account login credentials.

Scammers can exploit this information to gain access to email accounts and potentially other accounts if users reuse the same login credentials across different platforms. Once accessed, email accounts can be used to collect additional data, send phishing emails, distribute malware, and engage in other malicious activities.

If other accounts are compromised, they could be exploited to steal funds, make fraudulent purchases, commit identity theft, and more. Additionally, scammers may sell the stolen data to third parties. Therefore, it is crucial to avoid replying to suspicious messages from unknown senders, and avoid clicking links in them.

How do spam campaigns infect computers?

Threat actors spread malware via email by including malicious files or links in their deceptive messages. Some of these files can trigger an infection as soon as they are opened, while others may require the user to perform an action, such as enabling macros in a compromised Office document, to activate the malicious software.

More examples of files commonly used to deliver malware via email are PDFs, script files, archives, and executable files. When such emails contain links, clicking them can take users to sites that automatically download malware or deceive users into installing malicious programs manually.

How to avoid installation of malware?

Be wary of unsolicited, irrelevant emails from unfamiliar addresses, particularly those with links or attachments. If you receive such an email, do not open its contents. Avoid interacting with pop-ups, ads, or links on suspicious websites (and do not permit web pages of this kind to show notifications).

Always download software and files from reputable sources, such as official websites or trusted app stores. Keep your operating system and software up to date, and perform regular scans with a reliable security tool. If you have 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 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.

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 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. 

Example of a spam email:

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.
