RapperBot is a malware family derived from the Mirai botnet source code, targeting IoT devices through brute-forcing SSH credentials instead of Telnet. This modification allows RapperBot to compromise a broader range of devices, including those with more secure configurations. Unique among Mirai variants, RapperBot incorporates persistence mechanisms, ensuring continued access to compromised systems even after reboots or malware removal.
Disable password-based SSH authentication in favor of key-based methods. Regularly patch and update devices to eliminate known vulnerabilities. Monitor network traffic for unusual activity, such as brute-force attempts. Enforce rate-limiting and account lockout policies to prevent repeated login attempts.
