‘Website Customer Invoice’ Malware Email

Keep in eye out for a malicious email that supposedly contains a website customer invoice. The email, which has the subject “INVOICE [random numbers] Website customer”, claims that you can click a link to access the invoice in Microsoft Word (doc) format.

To make the email seem a little more professional, it includes a confidentiality clause like those that often appear in genuine business messages.

Email Does Not Contain an Invoice – Links to JavaScript Malware

However, the email is not a genuine invoice notification. Clicking the link downloads a malicious JavaScript file that, if opened, can download and install further malware.

JavaScript malware is often used to install ransomware. Once installed, ransomware can lock all of your computer’s files and then demand that you pay a fee to online criminals to receive a decryption key.

Malicious JavaScript is also used to install malware that can steal banking login credentials and other personal information from the infected computer.

The malware email does not specify what product the invoice is supposedly for or what company supposedly sent it. This vagueness is a deliberate ploy to trick people into clicking out of curiosity or concern.
