Few readers of this blog will believe that there aren't any security issues with Apple's macOS operating system, a point made rather unsubtly by yesterday's discovery of a flaw that lets anyone log into a computer running macOS High Sierra – as the root user, no less.
Those who have been following Patrick Wardle's work will certainly not be surprised by the fact that Macs do have security issues. His Objective See tools are widely lauded for their ability to detect existing and new threats, while his VB talks in 2014, 2015 and 2016 have all been very popular.
Patrick was back at VB2017 in Madrid, this time to look at a specific piece of macOS malware: FruitFly. He presented a paper in which he analysed the malware (more specifically, a variant of it discovered in January of this year) through a custom C&C server – a technique that will be of equal interest to researchers of malware on other platforms.
