– In 2022, Microsoft threat intelligence researchers discovered a new variant of a malware botnet that they called “Zerobot” (also referred to as “ZeroStresser”). This botnet was designed to launch distributed denial‑of‑service (DDoS) attacks and to insert advertisements into legitimate HTTP traffic, primarily targeting victims in China (96% of infections). The botnet was notably upgraded to exploit vulnerabilities in Apache web servers, Apache Spark data processing engines, and Grandstream communication devices. After the upgrade, Zerobot gained seven new DDoS attack capabilities, allowing it to launch more powerful and varied floods.

This paper examines ZeroStresser, a stress-testing/DDoS tool (also called a "stresser") known in cybercrime and security communities. It summarizes functionality, distribution, typical abuse patterns, legal and ethical considerations, detection and mitigation strategies, and recommendations for network defenders and policymakers. zerostresser
