"Although security vulnerabilities are discovered in Mac OS X on a monthly basis, the operating system remains a backwater for malware hackers. "We have seen an increase in bugs, but they haven't been critical," Amol Sarwate, vulnerability research manager for Qualys, a security auditing and vulnerability management company in Redwood Shores, Calif., told MacNewsWorld.
"There aren't enough Mac OS systems being used, to be exploited publicly by viruses and worms" he added...
Though incidents are increasing, most malware targeting OS X remains one-off,
proof-of-concept code. "They're things that show up once," he explained. "They serve no greater purpose other than
to show that they could be done."
