In early 2025, Chinese-backed espionage activities, particularly by the group RedMike, targeted telecommunications and semiconductor sectors using vulnerabilities in Cisco devices. The group successfully exploited known issues, maintaining control over systems of major global telecom companies. Notable targets included telecom providers and universities in various countries, indicating a focus on acquiring critical technological research. Despite receiving sanctions from the US for these activities, RedMike's attacks continued, posing significant threats to national security through potential exploitation of telecom infrastructure.
In the first half of 2025, it was observed that groups affiliated with China targeted key sectors like telecommunications and semiconductors through advanced cyber espionage activities.
The Chinese-backed espionage group RedMike exploited vulnerabilities in Cisco IOS XE devices, gaining elevated access to global telecommunications companies and maintaining persistent control.
Attacks included targets such as a US subsidiary of a British telecom provider and universities in the US, the Netherlands, Mexico, and Indonesia, focusing on strategic information.
The US imposed sanctions in January 2025 on the Chinese company Sichuan Juxinhe Network Technology due to its involvement with RedMike, indicating severe security risks from cyber activities.
