Chinese Hackers Exploit VSCode Remote Tunnels for Espionage
Chinese Cyberespionage Targets South European IT Service Providers in Operation Digital Eye
In a recent alarming development, major South European business-to-business (B2B) IT service providers have fallen victim to a suspected Chinese cyberespionage operation, part of the broader Operation Digital Eye campaign. This wave of cyber attacks, reported by The Hacker News, took place between June and July and involved sophisticated techniques that exploited Visual Studio Code Remote Tunnels and Microsoft Azure infrastructure for command-and-control operations.
The attackers aimed to infiltrate internet-exposed applications and database servers using SQL injection, allowing them to establish a foothold before deploying a series of advanced tactics including PHPsert webshell distribution, reconnaissance, credential compromise, and lateral movement. This operation underscores the growing threat of cyberespionage in the B2B sector, highlighting the need for enhanced cybersecurity measures.
Overview of the Operation Digital Eye Attack Campaign
- Attack Timeline: The cyber campaign unfolded between June and July.
- Primary Target: Major South European B2B IT service providers.
- Exploitation Techniques:
- SQL Injection: Initial compromise of internet-exposed apps and database servers.
- PHPsert Webshell Distribution: Utilized for maintaining access and furthering the attack.
- Mimikatz Injection: Custom techniques for pass-the-hash intrusions.
How the Attackers Operated
The threat actors demonstrated a calculated approach by leveraging trusted tools. Here’s how they executed their strategy:
- Visual Studio Code Remote Tunnels: This commonly used development tool was exploited to disguise malicious activities as legitimate operations.
- Microsoft Azure: The attackers utilized Azure infrastructure to enhance their command-and-control capabilities.
- Remote Code Execution: Both VSCode Remote Tunnels and SSH were employed to facilitate sophisticated remote code execution.
According to research from SentinelOne SentinelLabs and Tinextra Cyber, the use of Visual Studio Code Remote Tunnels highlights the practical and solution-oriented strategies employed by Chinese Advanced Persistent Threat (APT) groups to evade detection.
Implications for Cybersecurity
The Operation Digital Eye attacks reveal significant vulnerabilities in the cybersecurity landscape for B2B IT service providers. Organizations must take proactive measures to defend against such sophisticated threats, including:
- Regular Security Audits: Conducting comprehensive assessments of applications and infrastructure.
- Enhanced Monitoring: Implementing robust monitoring solutions to detect unusual activities.
- Employee Training: Educating staff about cybersecurity best practices to reduce risks associated with human error.
