rkhunter for Mac

rkhunter is a security tool used to check whether a system has been infected by a rootkit; its name translates literally to "rootkit hunter." A rootkit is a type of malicious program that excels at hiding deep within a system, making it very difficult for ordinary users to detect. rkhunter helps uncover suspicious tampering and hidden traces by scanning key locations in the system and comparing file signatures. It runs as a command-line tool and is suited to users with some Linux or Unix experience who care about server or local machine security, such as system administrators and security enthusiasts. If you suspect a machine has been compromised, or want to perform a regular security check, it can serve as a practical troubleshooting measure.
