The NSA alerts on PRC-Linked botnet threat
This cyber threat underscores the urgent need for enhanced security measures to protect against such pervasive threats.
The National Security Agency (NSA), in conjunction with the Federal Bureau of Investigation (FBI), United States Cyber Command’s Cyber National Mission Force (CNMF), and international allies, has issued a critical cybersecurity advisory. Titled ‘People’s Republic of China-Linked Actors Compromise Routers and IoT Devices for Botnet Operations,’ the advisory reveals the extensive activities of cyber actors affiliated with the People’s Republic of China (PRC).
These actors have breached internet-connected devices worldwide, establishing a massive botnet. To address this threat, the NSA has outlined several key mitigations aimed at helping device vendors, owners, and operators secure their devices and networks. These recommendations include regularly applying patches and updates, turning off unused services and ports, replacing default passwords with strong alternatives, and implementing network segmentation to reduce IoT device risks.
Furthermore, the advisory suggests monitoring network traffic for signs of DDoS attacks, planning device reboots to eliminate non-persistent malware, and upgrading outdated equipment with supported models. Moreover, NSA Cybersecurity Director Dave Luber has emphasised the importance of the advisory, noting that it provides crucial and timely insights into the botnet’s infrastructure, the geographical distribution of the compromised devices, and effective mitigation strategies.
According to the advisory, the botnet encompasses thousands of devices across various sectors, with over 260,000 devices compromised in North America, Europe, Africa, and Southeast Asia as of June 2024. Consequently, this extensive network of affected devices highlights the urgent need for enhanced security measures to protect against such pervasive cyber threats.
