What is "Coronavirus Email Virus"?

There's a number of variants of Coronavirus spam campaign, cyber criminals spread it with a purpose to deceive recipients into infecting their computers with malicious programs like Emotet, Agent Tesla, TrickBot, and other high-risk malware. They send emails that contain either a website link that is designed to download a malicious file/display unreliable content (e.g., phishing sites) or some malicious attachment. Either way, if opened (executed), those files/attachments install a certain malicious program. We strongly recommend to ignore this email, it has nothing to do with the actual Coronavirus.

Coronavirus Email Virus

This spam campaign variant is disguised as a letter from World Health Organization (WHO) regarding protective measures against the new Coronavirus. It suggests that the attached file or included website link contains information on how to prevent Coronavirus from spreading and avoid being infected with it. However, attached files or a files that get downloaded via the included link are designed to install one or another malicious program. As we mentioned in the introduction, this Coronavirus spam campaign is being used to spread different malicious programs. Either way, it is very likely that cyber criminals behind it attempt to infect computers with some Trojan or ransomware. Nevertheless, they could be using Coronavirus campaign to spread some other type of malware as well. Typically, they spread Trojans that are designed to steal sensitive information like logins, passwords, credit card details (or other banking information), etc., or open backdoors for other malicious software that could allow them do to the same. Ransomware is a type of software that encrypts files so that victims could not decrypt them without a tool (or tools) that usually can be purchased only from its developers. Simply said, victims of ransomware often lose not only data but also money. Research shows that the executable within "CoronaVirus_Safety_Measures.rar" file that is attached to one of the emails of this spam campaign is designed to spread Agent Tesla. A remote access tool which, if installed, allows to take control over the infected computer. One of its main features is keylogging - it can be used to record system keystrokes (record pressed keys). This feature can be used to steal accounts, credentials and a variety of other personal details, information. Nevertheless, no matter what malicious software cyber criminals behind this spam campaign attempt to distribute, attachments or website links in it must not be opened. By opening them recipients would risk to experience monetary, data loss, problems related to privacy, browsing safety, have their identities stolen, and other serious issues.

Here are other examples of spam campaigns that cyber criminals use/used with a purpose to trick recipients into installing malicious software: "Greta Thunberg Email Virus", "Christmas Party Email" and "UPS Email Virus". In most cases these spam campaigns are disguised as important, official letters from legitimate companies. Either way, recipients who open attachments or files downloaded through website links that are included in such emails infect their systems with high-risk malware that cyber criminals spread with a purpose to generate revenue in one or another way.

How did "Coronavirus Email Virus" infect my computer?

Research shows that cyber criminals spread malware through this spam campaign either by including some website link or attaching a malicious file to their email. Most commonly used file formats to spread malware through emails (attachments and/or website links in them) are malicious Microsoft Office, PDF document, executable file like .exe, archive file like ZIP, RAR or JavaScript file. Typically, those files infect systems when recipients execute (open) them. For example, if an attachment (or a file downloaded through a link) is a MS Office document and it is opened with a Microsoft Office 2010 or later, then it will asks for a permission to enable macros commands (editing). By getting such permission malicious document is allowed to install some malicious program. It is worth mentioning that older MS Office versions (that were developed before year 2010) do not include the Protected View mode. It means that they install malware without asking any permission.

How to avoid installation of malware?

No software should be downloaded (or installed) through third party downloaders (or installers), unofficial websites, Peer-to-Peer networks (e.g., torrent clients, eMule), and other similar tools, sources. It should be done by using official websites and direct links. Installed software should not be updated via unofficial, third party tools. The only safe way to achieve it is by using implemented functions and/or tools that are provided by official developers. The same applies to activation of licensed (paid) software. Besides, it is not legal to use various unofficial activation ('cracking') tools for that and they often cause installation of malware. Attachments that are included in irrelevant emails that are received from unknown, suspicious addresses should not be opened. It is worth mentioning that cyber criminals tend to disguise their emails as official, important, legitimate, etc. Attachments and/or website links in emails should be opened only when there is no reason to believe that it may be unsafe. And finally, it is important to regularly scan the operating system with a reputable anti-spyware or antivirus suite installed and remove detected threats as soon as possible. If you've already opened "Coronavirus Email Virus" attachment, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.
