The researchers found an unusual piece of malware, FruitFly, which infects some Mac computers. FruitFly spies on users through a computer camera, captures images and records keystrokes. There was a second version called FruitFly 2 at the beginning of the year.
It’s unclear how long FruitFly infects computers, but it was found that the code was changed to work with the Mac OS Yosemite, indicating that malware existed before October 2014. In recent years, malware Mac software has increased, but less common than Windows.
