A new malware attack for Mac OS X systems has been unearthed with serious implications for users. Known informally as "Puper", the attack comes in the form of a Trojan - a term used to describe malware that appears, to the user, to perform a desirable function but, in fact, facilitates unauthorized access to the user’s computer system. The Trojan disguises itself as a video program for OS X systems called "MacCinema" which once installed, infects the user with a script file named "AdobeFlash". The malicious script then launches itself every five hours, and attempts to download and launch other malware on the infected system retrieving important company data. So how can SMEs in the midlands protect themselves from falling foul to this new generation of attack?

When malware writers see an opportunity they go for it. A key reason for the success of this attack is the low levels of malware experienced by Mac users has resulted in greater levels of trust in installing additional programs. SMEs should maintain consistent levels of basic security measures including adopting a suspicious mindset of all program downloads. If presented with an additional program that doesn’t appear to have come from a business’s central IT system or computer vendor, employees should seek clarification from their IT department or management despite the download’s supposed credentials. Checking with Apple on the credibility of the program is also a best practice method as the company regularly reports and updates information on additional programs it has and hasn’t distributed.

Even with the general view that Macs are far less likely to be infected that an ordinary PC, it is essential that users ensure their operating systems are up to date and protected. In the computing world, six months is more than enough time for desktop security to become obsolete and overcome by viruses. SMEs should be vigilant in monitoring that all Macs are regularly checked for valid updates and policies are put in place to that end.

SMEs should be mindful that Apple may also be a victim of its own success. As Apple ownership rises, more malware writers are being drawn to the platform.
