In an era where cyber threats are becoming increasingly sophisticated, Japan has found itself at the center of a prolonged and highly targeted cyber-attack campaign. Since 2019, a China-linked threat actor known as MirrorFace, or Earth Kasha, has been systematically targeting Japanese organizations and individuals. The campaign, attributed to this advanced persistent threat (APT) group, has been linked to the theft of sensitive information related to Japan’s national security and cutting-edge technologies. With the National Police Agency (NPA) and the National Center of Incident Readiness and Strategy for Cybersecurity (NISC) sounding the alarm, the stakes have never been higher for Japan’s cybersecurity defenses.
of the MirrorFace Campaign
MirrorFace, believed to be a subgroup of the Chinese state-sponsored hacking collective APT10, has employed a range of sophisticated malware tools, including ANEL, LODEINFO, and NOOPDOOR, to infiltrate Japanese systems. The campaign has been ongoing since December 2019, with several key phases identified:
1. December 2019 to July 2023: MirrorFace targeted government bodies, think tanks, politicians, and media outlets using spear-phishing emails laden with malware such as LODEINFO, LilimRAT, and NOOPDOOR.
2. February to October 2023: The focus shifted to critical sectors like semiconductors, aerospace, and academia. Attackers exploited vulnerabilities in network devices to deploy tools like Cobalt Strike Beacon, LODEINFO, and NOOPDOOR.
3. June 2024 onwards: Think tanks, politicians, and media organizations were targeted with phishing emails carrying ANEL malware.
The group’s tactics are highly advanced, often executing malware within the Windows Sandbox—a virtualized environment that prevents persistent infections. This technique allows the malware to operate undetected by antivirus tools, with all traces erased upon system reboot. Over the five-year period, MirrorFace has been linked to over 200 cyber incidents, affecting government agencies, defense organizations, space research centers, and private firms involved in advanced technologies. Phishing emails often used themes like “Japan-US alliance” and “Taiwan Strait” to lure victims into downloading malicious attachments.
Notable incidents tied to MirrorFace include a cyber-attack on the Japan Aerospace Exploration Agency (JAXA) and a ransomware attack that disrupted operations at the Port of Nagoya in 2023. The NPA has issued warnings to raise awareness and encourage the implementation of robust security measures to mitigate further damage.

What Undercode Say:
The MirrorFace campaign is a stark reminder of the evolving nature of cyber threats and the increasing sophistication of state-sponsored hacking groups. This campaign highlights several critical aspects of modern cybersecurity challenges:
1. The Persistent Nature of State-Sponsored Threats
MirrorFace’s prolonged campaign underscores the persistence and resourcefulness of state-sponsored threat actors. Unlike financially motivated cybercriminals, these groups operate with strategic objectives, often targeting national security and advanced technologies. Their ability to adapt and refine their tactics over time makes them particularly dangerous.
2. Advanced Evasion Techniques
The use of the Windows Sandbox to execute malware is a testament to the group’s technical prowess. By operating in a virtualized environment, MirrorFace ensures that their malware leaves no persistent traces, making detection and attribution significantly more challenging. This technique also highlights the limitations of traditional antivirus solutions in combating advanced threats.
3. The Role of Social Engineering
Spear-phishing remains a cornerstone of MirrorFace’s strategy. By crafting emails with themes like “Japan-US alliance” and “Taiwan Strait,” the group exploits geopolitical tensions to manipulate targets into compromising their systems. This underscores the importance of cybersecurity awareness training for employees at all levels.
4. Sector-Specific Targeting
MirrorFace’s focus on sectors like semiconductors, aerospace, and academia reflects a strategic interest in Japan’s technological advancements. These industries are critical to national security and economic competitiveness, making them prime targets for espionage.
5. The Need for Proactive Defense
The NPA’s public disclosure of MirrorFace’s tactics is a step in the right direction. However, organizations must go beyond awareness and adopt proactive defense measures. This includes regular vulnerability assessments, endpoint detection and response (EDR) solutions, and threat intelligence sharing.
6. Geopolitical Implications
The attribution of MirrorFace to a China-linked group adds another layer of complexity to the already tense geopolitical relationship between Japan and China. Cyber-attacks of this nature are not just about data theft; they are also tools of geopolitical influence and coercion.
7. Lessons for the Global Community
While Japan is the primary target, the MirrorFace campaign serves as a cautionary tale for the global community. State-sponsored cyber-attacks are a transnational issue, and no country is immune. International cooperation and information sharing are essential to countering these threats.
8. The Human Factor
Despite the advanced technical capabilities of threat actors like MirrorFace, the human factor remains a critical vulnerability. Employees must be trained to recognize and report phishing attempts, and organizations should implement multi-factor authentication (MFA) to reduce the risk of credential theft.
9. The Role of AI in Cybersecurity
As cyber threats grow in sophistication, artificial intelligence (AI) and machine learning (ML) will play an increasingly important role in detecting and mitigating attacks. These technologies can help identify anomalous behavior and respond to threats in real-time.
10. A Call to Action
The MirrorFace campaign is a wake-up call for governments, organizations, and individuals to prioritize cybersecurity. In an interconnected world, the consequences of a successful cyber-attack can be far-reaching, affecting not just the targeted entity but also national security and global stability.

In conclusion, the MirrorFace campaign is a testament to the evolving nature of cyber threats and the need for a comprehensive, multi-layered approach to cybersecurity. By understanding the tactics, techniques, and procedures (TTPs) of threat actors like MirrorFace, organizations can better defend themselves against future attacks. The stakes are high, and the time to act is now.
