This one is disguised as a letter from World Health Organization regarding necessary precautions against Coronavirus that can be found in the attached document. This malspam campaign has a malicious MS Excel document attached to it. That document is designed to proliferate malicious software called Ursnif. This malware is capable of collecting user-system information, saved logins/passwords, web browsing activity and logging keystrokes. Cyber criminals can use it to steal login credentials for a variety of personal accounts (e.g., email, social media, banking-related accounts), credit card details and various other, sensitive information that could be misused to steal identities, accounts, make fraudulent transactions, purchases, and for other malicious purposes. It is worthwhile to mention that in this case Ursnif could be installed only if recipients would open a malicious attachment and enable macros commands (editing/content) in it. Therefore, files attached to these emails must be left unopened.

How did Mondiale della Sanita - Italia email virus infect my computer?

As mentioned in the second paragraph, Ursnif can be successfully installed only after execution the malicious MS Excel file (document) which is attached to the email. Also, that document cannot cause installation of malware without having macros commands enabled in it. Therefore, computers are safe as long as recipients leave that attachment unopened. t is worthwhile to mention that malicious documents opened with any Microsoft Office suite that was released before MS Office 2010 infect computers automatically. It is because they older versions do not ask for a permission to enable content/editing (macros commands). In other words, they do not include the Protected View mode which prevents malicious documents from installing malware automatically. More examples of files that cyber criminals send via email are malicious PDF documents, Microsoft Word documents, executable files (like .exe), other archive files (like ZIP, RAR), JavaScript files.

How to avoid installation of malware?

It is important to analyze received emails that have attachments or website links in them, especially if such emails are irrelevant and received from unknown, suspicious address. It is common cyber criminals send such emails with a purpose to trick users/recipients into executing a malicious file. Also, it is advised to download any software (and files) only from official, trustworthy pages and via direct links. Third party downloaders, installers, unofficial sites, etc., should not be used. Furthermore, installed software has to be activated and/or updated only with tools or implemented functions that are provided by official developers. Third party activation or updating tools  can cause installation of malware. Also, it is not legal to use any unofficial software activation ('cracking') tools to activate licensed programs. And finally, a computer should be scanned for threats regularly, it should be done with a reputable antivirus or anti-spyware suite. If you've already opened attachment in Mondiale della Sanita - Italia email, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.
