A huge batch of malicious emails designed to impersonate accounting giant MYOB is hitting inboxes this morning, posing a risk to those curious enough to view the attachment.
The email, delivered at a rate of thousands per minute, indicates that an invoice has been issued and requires payment.
Various iterations of the email have been sent across the morning, with different company names and invoice amounts being used. This is most likely an attempt to outrun antivirus software.
The fake invoice generally tells recipients they owe between $6300 and $6400, with the amount due today.
Adding to the likelihood that some recipients will fall for the scam, the well-formatted fraud email looks like a legitimate invoice from a company using MYOB software. It includes links to the real MYOB website.
But rather than being sent from MYOB, it’s delivered by the newly-registered domain myob-australia.com.
Those who click the link to ‘view invoice’ are directed to a compromised SharePoint website, which hosts a Trojan in the form of a JavaScript file. In some versions the link points to a zip file which encloses the JavaScript payload.
When executed, the JavaScript payload file installs itself to autorun at Windows startup and attempts to steal private information from internet browsers.
