Security researchers have found that cyber criminals are using booby trapped Microsoft Word documents to try and spread malware among Mac computer users.
Similar malicious Word docs have been used to target Windows users for years, but now the same tactics are being used to infect Macs.
The malicious file contains a Macro that executes in the background without the user knowing. Once executed it downloads software that can monitor webcams, read browser history and steal passwords.
Macro malware has targeted Windows users for well over a decade. However, despite seeing a decrease in this kind of attack on Windows, there has been a surge in the number of cases hitting Mac users.
Macro malware has been around of so long primarily because it is so effective and can lay undetected for long periods of time.
With it being hidden inside an innocent looking Word document, the malicious file doesn’t set off any alarm bells with both users and anti virus software – or at least it doesn’t until a virus has been installed onto the machine, by which point it can sometimes be too late.
This particular new form of macro malware targeting Mac users has proved so effective as it includes include ‘Donald Trump’ in the file name.
If you receive the Word document “U.S. Allies and Rivals Digest Trump’s Victory — Carnegie Endowment for International Peace” from an email address you are not familiar with, whatever you do, do not open it.
