The world's most advanced cyber espionage group, Salt Typhoon, has been targeting edge network devices across the globe, exploiting vulnerabilities in Cisco, Ivanti, Palo Alto Networks, and other manufacturers to breach over 600 organizations. With its sophisticated tactics and unique advantage in telecommunications systems, Salt Typhoon poses a significant threat to global cybersecurity.
Salt Typhoon is a China-linked advanced persistent threat (APT) actor carrying out highly sophisticated cyber espionage campaigns. The group has been targeting networks since at least 2019, exploiting vulnerabilities in edge network devices from various manufacturers. Salt Typhoon's attacks involve gaining initial access into networks through exploited vulnerabilities, then leveraging compromised devices and trusted connections to pivot into other networks. The group often modifies routers to maintain persistent, long-term access to networks, allowing for extensive discovery actions and capture of credentials. Salt Typhoon's familiarity with telecommunications systems offers a unique advantage in defense evasion, making it challenging for defenders to detect and respond to threats. The group has been observed using various tactics, including enabling sudo privileges on Cisco IOS XR devices and utilizing authentication protocols like TACACS+ Salt Typhoon's attacks have been characterized by their sophistication and scale, targeting over 600 organizations worldwide. The impact of Salt Typhoon's attacks cannot be overstated, posing significant challenges for defenders due to the group's unique advantage in telecommunications systems.
The world of cybersecurity has been abuzz with the news of a highly sophisticated and coordinated cyber espionage campaign carried out by a group known as Salt Typhoon. This China-linked advanced persistent threat (APT) actor has been wreaking havoc on networks across the globe, leaving a trail of compromised devices and exploited vulnerabilities in its wake.
According to a joint cybersecurity advisory published by authorities from 13 countries, including Australia, Canada, the Czech Republic, Finland, Germany, Italy, Japan, the Netherlands, New Zealand, Poland, Spain, the U.K., and the U.S., Salt Typhoon has been actively targeting networks since at least 2019. The group's modus operandi involves exploiting vulnerabilities in edge network devices from various manufacturers, including Cisco, Ivanti, Palo Alto Networks, Fortinet firewalls, Juniper firewalls, Microsoft Exchange, Nokia routers and switches, Sierra Wireless devices, and Sonicwall firewalls.
The exploitation of these vulnerabilities allows Salt Typhoon to gain initial access into the networks of targeted organizations. However, it is crucial to note that these vulnerabilities are not exhaustive, and the threat actors may also target other devices such as network-attached storage (NAS) systems and industrial control systems (ICS).
Once inside the network, Salt Typhoon leverages compromised devices and trusted connections to pivot into other networks. The group often modifies routers to maintain persistent, long-term access to networks. This allows them to conduct extensive discovery actions and capture network traffic containing credentials, which they use to burrow deeper into the networks.
The agencies pointed out that Salt Typhoon's familiarity with telecommunications systems offers them a unique advantage when it comes to defense evasion. The group's knowledge of these systems enables them to tailor their attacks to specific targets, making it challenging for defenders to detect and respond to the threats in time.
Furthermore, Salt Typhoon has been observed enabling the sshd_operns service on Cisco IOS XR devices to create a local user and grant it sudo privileges to obtain root on the host OS after logging in via TCP/57722. This allows the group to establish persistent access to target networks and conduct lateral movement within the environment.
The threat actors also utilize authentication protocols such as Terminal Access Controller Access Control System Plus (TACACS+) to enable lateral movement across network devices, while simultaneously conducting extensive discovery actions and capturing network traffic containing credentials via compromised routers.
According to Google-owned Mandiant, which was one of the many industry partners that contributed to the advisory, Salt Typhoon's attacks are characterized by their sophistication and scale. The group has been observed targeting over 600 organizations worldwide, including 200 in the U.S., and 80 countries.
John Hultquist, Chief Analyst at Google Threat Intelligence Group, stated, "An ecosystem of contractors, academics, and other facilitators is at the heart of Chinese cyber espionage." Contractors are used to build tools and valuable exploits as well as carry out the dirty work of intrusion operations. They have been instrumental in the rapid evolution of these operations and growing them to an unprecedented scale.
The impact of Salt Typhoon's attacks cannot be overstated. The group has demonstrated a remarkable ability to adapt and evolve, exploiting vulnerabilities in edge network devices and leveraging compromised devices to pivot into other networks. This level of sophistication poses significant challenges for defenders, who must contend with the threat actors' unique advantage in telecommunications systems.
In light of these findings, it is essential that organizations take proactive measures to defend against Salt Typhoon's attacks. This includes implementing robust security controls, conducting regular vulnerability assessments, and providing employees with awareness training on cybersecurity best practices.
Furthermore, governments and international organizations must also take a closer look at the issue of Chinese cyber espionage. The revelation that Salt Typhoon is linked to three Chinese entities, Sichuan Juxinhe Network Technology Co., Ltd., Beijing Huanyu Tianqiong Information Technology Co., Ltd., and Sichuan Zhixin Ruijie Network Technology Co., Ltd., raises serious concerns about the scope and scale of China's cyber espionage activities.
As the cybersecurity landscape continues to evolve, it is crucial that we remain vigilant and proactive in defending against threats like Salt Typhoon. By working together, governments, organizations, and individuals can mitigate the impact of these attacks and protect the integrity of our global networks.
