Cyber espionage campaigns are becoming increasingly sophisticated, with nation-state actors deploying advanced malware to infiltrate critical diplomatic and governmental infrastructures. One such operation, Operation AkaiRyū (RedDragon), has been attributed to the China-linked threat actor MirrorFace, a subgroup of APT10. This campaign targets a Central European diplomatic institute, using spear-phishing lures themed around the upcoming World Expo in Osaka to deliver powerful backdoors and remote access tools.
The attack demonstrates a tactical shift from MirrorFace’s traditional targeting of Japanese entities, marking a significant expansion in its victim profile to include European diplomatic channels.
European Faces in the Mirror: A New Target Set
MirrorFace’s infiltration of European embassies, consulates, and foreign ministries threatens the security of classified documents, strategic communications, and diplomatic negotiations. The operation endangers not only national security but also broader international relations.
Targeted entities include:
Diplomatic institutes and embassies in Central and Western Europe.
Foreign ministries responsible for international cooperation and treaty negotiations.
Government-affiliated organizations handling sensitive political and economic data.
The scale of these attacks highlights MirrorFace’s growing ambition to expand beyond its known Japanese targets, posing a direct threat to European diplomatic security frameworks.
The Perilous Reflex: MirrorFace’s Complex Attack Chain
Operation AkaiRyū employs a multi-layered, highly covert intrusion strategy:
Spear-Phishing Delivery – Victims receive emails with lures referencing the World Expo in Osaka.
DLL Side-Loading with ANELLDR – Clicking the malicious link triggers a loader component (ANELLDR) that decrypts and executes:
ANEL backdoor (aka UPPERCUT)
HiddenFace modular malware (also known as NOOPDOOR)
AsyncRAT Custom Variant Deployment – A customized version of AsyncRAT is used for stealthy surveillance and data exfiltration.
Stealth Access via Visual Studio Code Remote Tunnels – Attackers establish concealed remote access to infected devices.
Operational Security Techniques – MirrorFace uses advanced tactics, including:
Deletion of delivered tools post-execution.
Clearing Windows event logs to erase forensic traces.
Running malware inside Windows Sandbox to avoid detection and analysis.
This evolving toolkit showcases the sophistication and adaptability of MirrorFace’s espionage operations.
Sealing Diplomatic Channels: Defensive Measures
Defending against such state-level cyber espionage operations requires robust and proactive security measures. Organizations handling diplomatic or governmental communications should adopt the following:
Advanced Email Security – Deploy solutions that detect spear-phishing and social engineering attacks.
Sandboxing of Attachments – Isolate and analyze potentially malicious documents in a safe environment.
Endpoint Monitoring – Detect unusual tunneling activity and suspicious remote access behavior.
Strict Log Retention Policies – Ensure that logs are archived and protected to identify and investigate cover-up attempts.
Threat Intelligence Integration – Keep abreast of APT tactics and indicators of compromise (IOCs) for MirrorFace and related groups.
Regular Security Audits and Penetration Testing – Validate that security controls can withstand sophisticated attacks.
Operation AkaiRyū marks a significant escalation in the cyber espionage landscape, with MirrorFace expanding its operations to target European diplomatic institutions. The deployment of customized malware, use of advanced evasion techniques, and targeting of high-value geopolitical entities highlight the group’s strategic intent.
To counter these advanced threats, organizations must implement multi-layered defenses, continuous monitoring, and strong incident response plans. As geopolitical tensions rise, vigilance and readiness are essential to protect sensitive information from the digital flames of the MirrorFace Red Dragon.
