Hacker groups based overseas have initiated cyberattacks on China and other nations, leveraging a multitude of malicious websites and IP addresses. These attacks, which involve tactics such as deploying botnets and exploiting backdoor vulnerabilities, pose a significant threat to domestic network entities and internet users. Notably, these malicious addresses are predominantly located in the United States, the Netherlands, Switzerland, Belgium, Poland, South Africa, and Lithuania. In response, national security departments have maintained a heightened state of vigilance against such activities.
