Avoid getting scammed by fake "Maersk" emails

Also Known As: Maersk spam
Damage level: Severe

What is "Maersk Email Virus"?

"Maersk Email Virus" is categorized as a spam campaign and a scam. Like most spam campaigns of this type, cyber criminals (scammers) use it to infect people's computers. To achieve this, they attach a malicious file (or include a website link leading to it) and hope that someone will open it.

In this case, "Maersk Email Virus" is used to distribute a malicious program called Pony. This spam (email) campaign is a typical scam that should not be trusted. More importantly, the included website link should not be opened.

Maersk Email Virus

"Maersk" email virus overview

This scam is presented as an email (invoice) from Maersk, a Danish business conglomerate. It states that an invoice and documents are ready and asks recipients to check them by clicking the "click the attach to View, download and print your invoices and statements" link. Note that Maersk has nothing to do with this.

Scammers often disguise themselves by using names of well-known companies. If clicked, the link will trigger download of the "maersk line invoice.ace" compressed file. This file will download and install Pony, a malicious program that steals personal data.

It records information such as logins and passwords and then sends the details to a remote server controlled by cyber criminals. They use this information to gain access to bank accounts. Therefore, having this program installed can lead to financial loss. To avoid this, we strongly recommend that you ignore the "Maersk Email Virus" email and other similar emails.

Malspam campaign examples

Similar spam campaigns are "Confirm Bank Account Email Virus", "Paychex Email Virus", and "DSKD Email Virus". These are just some examples from many similar scams. All are proliferated to infect computers with malicious programs. Pony is one of many possible infections.

These emails can also be used to infect computers with other high-risk viruses such as Adwind, TrickBot, FormBook, LokiBot, and so on. Cyber criminals generally use them to steal sensitive information that can be used to generate revenue. This can cause financial loss and other problems.

How did "Maersk Email Virus" infect my computer?

In this case, Pony infects computers when the "click the attach to View, download and print your invoices and statements" link is clicked and the downloaded "maersk line invoice.ace" file is opened. It cannot be installed without first clicking the aforementioned link.

The same applies to other spam campaigns: they contain malicious attachments that must first be opened. Typically, cyber criminals attach Microsoft Office or PDF documents, JavaScript files, executables (.exe files), or archives (ZIP, RAR and so on). They cannot cause infections if they remain opened.

How to avoid installation of malware?

Do not open attachments or links included in irrelevant emails received from suspicious, unknown addresses. These emails are usually presented as legitimate (and official), however, they cannot be trusted. Furthermore, do not download software from unofficial websites or using Peer-to-Peer networks (torrent clients, eMule, or other such tools), third party downloaders, etc.

Download from official websites and use direct links. Software (or operating systems) should not be activated using third party "cracking" tools. These allow people to illegally bypass paid activations, however, they are used by cyber criminals to cause computer infections. Have reputable anti-spyware or anti-virus software installed and enabled.

These tools prevent computer infections by malware or other threats. If you have already opened "Maersk Email Virus" attachment, 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. Cyber criminals send these emails by the thousand with the hopes that at least some of the recipients will fall for their scams.

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

If you have provided account credentials - immediately change the passwords of all potentially compromised accounts and contact their official support. And if you have disclosed other private data (e.g., ID card details, credit card numbers, etc.) - contact relevant authorities without delay.

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

No, reading a spam email will not initiate any system infection processes. Malware download/installation is triggered when the attachments or links present in such emails - are opened/clicked.

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

Whether an infection was jumpstarted may depend on the opened file's format. If it was an executable (.exe, .run, etc.) - most likely, yes. However, you might have avoided having your system infected if it was a document (.doc, .xls, .pdf, etc.). Since these formats may require additional user interaction (e.g., enabling macro commands) - to initiate malware download/installation.

Will Combo Cleaner remove malware infections present in email attachments?

Yes, Combo Cleaner can detect and eliminate nearly all known malware infections. However, it must be stressed that sophisticated malicious software usually hides deep within systems - therefore, running a complete system scan is crucial.
