According to a post by F-Secure Labs
, the number of Mac-based security threads jumped in 2011 but still remain far below that of Windows PCs. A total of 58 unique variants were detected from April through December according to the Labsí Threat Research Team.
Of the 57, nearly half (29 to be specific) were Trojan downloaders, which F-Secure
defines as a type of Trojan horse program that secretly downloads a slew of malicious files from a remote server, then installs and executives them.
The company didnít compare directly the 2011 results with the Macís 2010 threat numbers, or with Windowsí comparable numbers, except to show that there had been an increase in the number of threads for the Mac in 2011. The company didnít reveal additional data either but their recent blog post did link to the full Excel file spreadsheet on the emerging Mac threats.
The second most common threat category, with 15 detected issues, were backdoors, or remote administration utilities that are designed to slip past security mechanisms to secretly control a program, computer, or even a network. Of the remaining detected viruses were seven Trojans were described by F-Secure
to be non-replicating, deceptive programs that perform additional actions without the userís knowledge or permission. The other seven were rogues or antivirus program software that uses false or deceptive tactics to pressure users into installing the code, which once loaded, would not work as claimed.
The research found by the company shows what appears to be a bit of a roller-coaster threat cycle for Macs last year. Threats continue to rise then fell, peaking in June and again in October.
