In an era where cyber-espionage has become a critical tool for state-backed actors, Japan finds itself at the center of a sophisticated and ongoing hacking campaign. The National Police Agency (NPA) and the Cabinet Cyber Security Center in Japan have identified the Chinese state-backed hacking group “MirrorFace” as the perpetrator behind a series of cyber-attacks targeting the nation since 2019. This campaign, characterized by its evolving tactics and high-value targets, underscores the growing threat of cyber-espionage in the geopolitical landscape. From exploiting software vulnerabilities to leveraging advanced evasion techniques, MirrorFace has demonstrated a relentless pursuit of Japan’s technological and national security secrets. This article delves into the details of the campaign, its phases, and the measures recommended to counter such threats.

1. The NPA and Cabinet Cyber Security Center in Japan have linked a cyber-espionage campaign to the Chinese state-backed hacking group MirrorFace, active since 2019.
2. MirrorFace, also known as “Earth Kasha,” has targeted Japanese politicians, government entities, and technology sectors to steal advanced technology and national security intelligence.
3. The group employs phishing emails, malware like ‘MirrorStealer’ and ‘LODEINFO,’ and exploits vulnerabilities in networking equipment (e.g., CVE-2023-28461, CVE-2023-27997, CVE-2023-3519).
4. Three distinct campaigns have been identified:
– Campaign A (2019–2023): Targeted think tanks, government entities, politicians, and media via malware-laden emails.
– Campaign B (2023): Exploited software vulnerabilities to target Japan’s semiconductor, manufacturing, ICT, academia, and aerospace sectors.
– Campaign C (2024–present): Used malicious email links to infect academia, think tanks, politicians, and media.
5. MirrorFace employs advanced evasion techniques, including the use of Visual Studio Code (VSCode) tunnels and Windows Sandbox to bypass detection.
6. VSCode tunnels, set up by the ANEL malware, allow remote command execution, while Windows Sandbox isolates malware execution from the host system, evading antivirus detection.
7. The NPA recommends monitoring PowerShell logs, VSCode domain communications, and Windows Sandbox activity to detect and mitigate threats.
8. Organizations are advised to audit process creation on host systems to identify unauthorized use of Windows Sandbox.

What Undercode Say:
The MirrorFace cyber-espionage campaign against Japan is a stark reminder of the evolving sophistication of state-backed hacking groups. This campaign is not just a series of isolated attacks but a well-orchestrated effort to infiltrate and exploit Japan’s technological and governmental infrastructure. Here’s a deeper analysis of the implications and lessons from this campaign:
1. Geopolitical Implications:
The targeting of Japan’s semiconductor, aerospace, and manufacturing sectors highlights China’s strategic interest in acquiring advanced technologies to bolster its own industries. This aligns with China’s broader goals of reducing dependency on foreign technology and achieving self-sufficiency in critical sectors. The campaign also underscores the use of cyber-espionage as a tool for geopolitical leverage, particularly in regions with strained diplomatic relations.
2. Tactical Evolution:
MirrorFace’s use of VSCode tunnels and Windows Sandbox demonstrates a shift towards more sophisticated evasion techniques. By leveraging legitimate tools like VSCode and built-in Windows features, the group minimizes the risk of detection while maintaining persistent access to compromised systems. This tactic is not unique to MirrorFace; other Chinese state-sponsored groups like STORM-0866 and Sandman APT have also adopted similar methods. This trend suggests a growing emphasis on operational security among state-backed hackers.
3. Targeted Sectors:
The focus on
4. Defensive Recommendations:
The
– Regularly updating and patching software to mitigate vulnerabilities.
– Monitoring network traffic for unusual patterns, such as unauthorized communications with VSCode domains.
– Implementing strict access controls and auditing mechanisms to detect the use of tools like Windows Sandbox.
– Educating employees about phishing and social engineering tactics to reduce the risk of initial compromise.
5. Broader Cybersecurity Trends:
The MirrorFace campaign is part of a larger trend of state-sponsored cyber-espionage targeting critical infrastructure and intellectual property. As nations increasingly rely on digital systems, the stakes of cyber-attacks continue to rise. This underscores the need for international cooperation and robust cybersecurity frameworks to deter and respond to such threats.
6. Future Outlook:
The persistence of
In conclusion, the MirrorFace campaign against Japan serves as a case study in the complexities of modern cyber-espionage. It highlights the need for continuous innovation in cybersecurity practices and the importance of collaboration between governments, industries, and cybersecurity experts to safeguard national and economic security. As the digital battlefield expands, the lessons learned from this campaign will be crucial in shaping future defenses against state-backed cyber threats.
