Broader Implications and Sanctions

Sanctions on Integrity Technology Group

In line with reactionary measures, the Treasury Department’s Office of Foreign Assets Control (OFAC) imposed sanctions on Integrity Technology Group, Incorporated, another Chinese cybersecurity entity. This company was accused of supporting hacking group Flax Typhoon in a sustained campaign against U.S. critical infrastructure. The sanctions signify a firm stance against entities aiding and abetting cybercriminals, sending a strong message about the consequences of such malign activities.

The imposition of sanctions is not an isolated incident; it is part of broader international efforts to address cyber threats at state and corporate levels. Driving accountability and repercussions through economic and state-sanctioned measures aims to deter potential cyber adversaries. At the same time, these actions continuously highlight the importance of cohesive, international collaboration in fighting cybercrime, as intrusions often transcend borders and affect multiple global stakeholders.

Series of Cyber Intrusions by Chinese Actors

Notably, this attack on the Treasury is part of a larger series of cyber intrusions by Chinese actors such as Volt Typhoon and Salt Typhoon, targeting U.S. infrastructure and telecommunications networks. The Wall Street Journal disclosed over the past weekend that among the breached telecom firms by Salt Typhoon were prominent companies like Charter Communications, Consolidated Communications, and Windstream. Previously identified telecom entities include AT&T, T-Mobile, Verizon, and Lumen Technologies.

These attacking campaigns on major telecom providers indicate a concerted effort by Chinese threat actors to disrupt and siphon critical data from essential services. The vulnerabilities exploited by these groups lead to significant security concerns, as telecom systems are integral to the communication infrastructure of a country. Tackling these wide-scale breaches requires not just advanced technical responses but also a deep understanding of the adversaries’ tactics, techniques, and procedures.

Cyberattacks on Taiwanese Entities

Increase in Cyber Incidents

Taiwan’s National Security Bureau (NSB) reports an uptick in cyberattacks by China against both Taiwanese government and private sector entities. The NSB registered 906 cyber incidents in 2024, an increase from 752 in 2023. The attack strategies employ vulnerabilities exploited in Netcom devices, living-off-the-land techniques to avoid detection, and malware deployment for further attacks and data exfiltration. These variations of entry points and tactics highlight the need to modernize and fortify existing cyber defense mechanisms.

The growing number of incidents each year underscores the persistent and evolving threat landscape faced by Taiwan. Not only do these attacks disrupt the operational capabilities of the targeted entities, but they also pose significant risks to sensitive, proprietary, and personal information. Collaborative security efforts between public sectors, private companies, and international partners are key to defending against increasingly sophisticated cyber adversaries.

Methods and Targets

Some common methods include spear-phishing targeting civil servants, distributed denial-of-service (DDoS) assaults on transportation and the financial sector during PLA military drills, ransomware attacks within the manufacturing sector, efforts to steal patented technologies from high-tech startups, and the theft of personal data from Taiwanese nationals for sale on cybercrime forums. The targeted assaults reflect a comprehensive strategy that aligns with broader geopolitical objectives, aiming to weaken and destabilize Taiwan’s vital sectors.

Taiwan’s proactive reporting and management of these security incidents have been pivotal in mitigating the wider repercussions stemming from these cyberattacks. However, elucidating these methods and targets also emphasizes the necessity for increased vigilance and the establishment of more stringent cybersecurity practices not only within Taiwan but also across global networks to preempt and counter cyber threats more effectively.
