DocuSign Email Virus

Also Known As: DocuSign spam
Damage level: Medium

What is DocuSign Email Virus?

"DocuSign Email Virus" is another spam email campaign used to proliferate a high-risk trojan called TrickBot. Developers send thousands of emails stating that users have received a "secure" document and must review and sign it. This is a scam - the opened MS Word document will stealthily download and install the TrickBot trojan.

DocuSign Email Virus malware

The email essentially states that users must electronically sign documents, however, this is a simple attempt to trick them into opening malicious documents that download and install malware. Note that the email contains the logo of DocuSign, a legitimate company. This is very common amongst cyber criminals.

They register email addresses and domains by including names of popular companies and governmental agencies. This is done to give the impression of legitimacy - it is much simpler to trick users into opening documents received from familiar names.

TrickBot is high-risk trojan designed to gather personal information. Immediately after infiltration, it hijacks browsers and modifies visited website content so that entered logins/passwords are saved on a remote server controlled by cyber criminals.

The criminals can then gain access to users' personal accounts (social networks, emails, banks, etc.) Therefore, the presence of a malware such as TrickBot might lead to serious privacy issues and significant financial loss.

If you have recently opened emails distributed via the "DocuSign Email Virus" spam campaign, you should immediately scan the system with a reputable anti-virus/anti-spyware suite and eliminate all threats.

There are a number of trojans similar to TrickBot including, for example, Adwind, Emotet, and FormBook. Most are distributed using spam email campaigns. In addition, these viruses typically have identical behavior: they collect information.

In some cases, however, trojans also proliferate other high-risk viruses, such as ransomware. In any case, these viruses pose a significant threat to your privacy and Internet browsing safety.

How did DocuSign Email Virus infect my computer?

As mentioned above, "DocuSign Email Virus" distributes a malicious Microsoft Word document that, once opened, asks users to enable macro commands. By complying, users grant permission for macro command within the document to run commands that stealthily download and install malware. This malware distribution method does, however, have a major flaw.

The attachment is unable to download malware if it is opened using any software other than MS Word. If the file is opened using another app that is capable of reading .doc format, TrickBot will not be downloaded. In addition, TrickBot targets only Microsoft Windows Operating System and users of other platforms are safe.

How to avoid installation of malware?

To prevent this situation, be very cautious when browsing the Internet. Carefully analyze each email attachment received. Files that seem irrelevant and those received from suspicious/unrecognizable email addresses should never be opened. They should be deleted immediately, without reading. In addition, have a reputable anti-virus/anti-spyware suite installed and running.

More recent versions (2010 and above) of MS Office open newly-downloaded documents in "Protected View" mode. This prevents malicious attachments from downloading and installing viruses. Therefore, using older MS Office versions is risky and not recommended.

The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. If you have already opened the "DocuSign 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.
