A new malware has been found targeting macOS users and spreading as an update for a legitimate program, as it looks to steal people’s sensitive data, establish persistence on the vulnerable device and, ultimately, deploy ransomware. 

Cybersecurity researchers Bitdefender recently discovered the campaign, called RustDoor, and found it was built on the Rust programming language, granting its operators a number of possibilities, including listing running processes, executing arbitrary shell commands, creating new directories, changing and removing existing ones, exfiltrating files, terminating other malware processes, and more.
