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 SHA1: 609088c54b99432aab212f35cfe74030b52f0320
Image of disassembly showing a new macOS backdoor using the deprecated CLI tool 'SetFile'.
