In 2011, IDC reported that Mac sales increased by 51% among small offices (fewer than 10 employees). Meanwhile, Mac sales among small businesses (with 10–99 employees) and medium-sized businesses (with 100–499 employees) rose by 93.5% and 56.7%, respectively.
Macs aren’t immune to malware
In fact, Mac malware have been seen since floppy disks were still in use. Mac malware, then known as “viruses,” like Elk Cloner, MDEF, and nVIR spread via floppy disks as early as 1982. Worms like LEAP and LAMZEV also wreaked havoc on Macs in the past. And as the Mac user base continued to grow, so did the Mac malware volume, specifically Domain Name System (DNS) changers and rogue antivirus tailor-made for the OS X platform.
The Flashback malware outbreak in 2012 infected over 600,000 Macs.
Cross-platform vulnerabilities are affecting Macs
Java exploits—zero day or not—are transcending boundaries. Cross-platform vulnerabilities continue to grow in number, giving bad guys control over infected systems, regardless of OS. Sophisticated malware like Crisis, which transforms Macs into audio surveillance devices, also plagued users in an attack.
Unpatched virtual environments on Macs are potential holes cybercriminals can exploit as well. Just because you don’t use applications all the time, that doesn’t mean they should remain unpatched.
Though regular patching on your part helps, it’s also not a cure-all. Vendor failure to issue patches also puts you at risk. The Flashback incident, for instance, put Apple in a bad light. The company was accused of being slow in issuing patches compared with competitors, indirectly causing users grief as they fell prey to click-fraud Trojans.
Apple recorded its highest number of vulnerabilities and issued a record number of 83 patches for security flaws in Safari in March 2012.
Apple’s "walled garden" approach doesn’t ensure iOS security
The close restrictive control that Apple applies to its device ecosystem forms its so-called “walled garden.” This can be both a good and a bad thing.
It’s good because Apple adheres to rigorous processes against threats. This doesn’t translate to malware immunity though, as the Flashback outbreak showed.
It’s bad because organizations can mistakenly use the walled garden as an excuse for lax security measures. Trend Micro is one of the vendors providing business security software for Apple computers.
