The sophisticated RapperBot botnet campaign targeted digital video recorders (DVRs) worldwide, exploiting vulnerable IoT devices to execute large-scale DDoS attacks. The campaign, a variant of the Mirai malware, compromised DVR systems to gain unauthorized access to surveillance cameras, leading to significant privacy and security issues. The attack on X (formerly Twitter) on March 10, 2025, caused a service disruption, demonstrating the malware's persistence and evolution over three years. The attackers exploited weak default passwords and infrequent firmware updates in DVRs, making them ideal for long-term botnet recruitment. The campaign's reach was amplified by targeting DVRs manufactured by Korean OEM ITX Security, distributed across multiple brands.
