Image of disassembly showing a new macOS backdoor using the deprecated CLI tool 'SetFile'.

This #macOS backdoor uses /usr/bin/SetFile to hide itself in the Finder. SetFile was deprecated in Xcode 6 (that's 2014 to humans)...not sure why it makes sense to declare smth 'deprecated' then leave it in the OS for 10+ years. 🤷‍♂️ #apple #malware
