US Campaign Aims to Eject China's 'Salt Typhoon' Hackers From Telecom Networks
The United States and its allies have launched a major effort to remove the "Salt Typhoon" Chinese state-sponsored hacking group from their countries' telecommunication networks. This coordinated campaign is part of a 37-page joint alert published by the FBI, National Security Agency, and partner agencies in Canada, Europe, and Japan.
The Threat: Understanding the Salt Typhoon Group
The Salt Typhoon group has been identified as a significant threat to global telecommunications' privacy and security norms. Investigators have discovered that the group has been active since at least 2019, conducting a major cyber-espionage campaign that breached multiple countries' networks. This espionage activity targeted over 80 countries, including Australia, Canada, New Zealand, the United Kingdom, and many others.
The scope of the Salt Typhoon Group's activities
FBI Assistant Director Brett Leatherman revealed in an interview with The Wall Street Journal that Salt Typhoon targeted more than 600 companies for spying purposes. This raises concerns about the group's intentions and capabilities. The hackers may have been infiltrating US networks for years, enabling them to steal call data from millions of people.
The Unsettling Reality: How Salt Typhoon Hacks
The Salt Typhoon group accesses telecom networks through existing software flaws in networking products, rather than publicly unknown ones. This means that the hackers are exploiting vulnerabilities that have been previously discovered and patched by manufacturers or made available to the public. However, it's essential to note that exploitation of zero-day vulnerabilities has not been observed to date.
The tactics, techniques, and procedures (TTPs) used by Salt Typhoon
The alert notes that Salt Typhoon focuses on targeting vulnerable "backbone" and other "edge" routers at telecommunication providers. These actors often modify routers to maintain persistent, long-term access to networks. This highlights the need for companies and organizations to prioritize network security and implement effective measures to detect and prevent malicious activity.
The US Response: A Call to Action
The FBI has published a joint alert to offer practical steps to improve visibility and detect malicious activity early, involving Salt Typhoon. The agency emphasizes the importance of stronger collaboration with partners to identify and counter this activity at the earliest stages. This is particularly crucial given Beijing's indiscriminate targeting of private communications.
The US today published the alert as a call to action for companies, organizations, and individuals to take immediate steps to protect themselves from the Salt Typhoon group's activities. The alert serves as a reminder that cybersecurity is everyone's responsibility and that vigilance is key in preventing cyber-attacks.
To stay safe from the Salt Typhoon group's activities:
* Regularly update your software and operating system to ensure you have the latest security patches. * Implement robust network security measures, including firewalls, intrusion detection systems, and antivirus software. * Conduct regular security audits to identify vulnerabilities in your networks and address them promptly.
