How Hackers Use Visual Studio Code Tunnels to Spy on Computers
Imagine you’re running a business and suddenly, a group of hackers sneaks in without you noticing, using a common tool you trust daily. That’s what happened with a cyber attack called “Operation Digital Eye,” which used Visual Studio Code Remote Tunnels—a tool primarily designed for programmers—to spy on IT providers. This sneaky mission, allegedly orchestrated by hackers linked to China, is a wake-up call for all small business owners and entrepreneurs about the importance of cybersecurity.
Who Are the Hackers?
The operation is believed to be the work of a group potentially connected to China. However, pinpointing the exact group is challenging due to the common sharing of tools and methods among such hacker groups in the region.
Tools and Tricks Used
The hackers cleverly utilized popular tools like Visual Studio Code Remote Tunnels and Microsoft’s Azure services. These platforms are legitimate and widely used, so their activities didn’t stand out as suspicious at first glance. This allowed them to maneuver freely and undetected, which is a serious concern for any business using these tools.
How Did the Hackers Get In?
Think of it like finding a hidden door into a secret club. The hackers used a trick called SQL injection to break into systems through weaknesses in internet-facing applications. They used a tool named SQLmap to automate this process, making it efficient and effective for penetrating security defenses.
Once inside, they set up a digital trap door with a tool known as PHPsert, allowing them to come and go as they pleased. To make matters worse, they employed a modified version of Mimikatz—a tool that steals passwords—letting them operate as if they were legitimate users.
The Attack Strategy
The hackers’ primary aim was to remain hidden while gaining control over IT companies. Taking over these companies wasn’t just about accessing their data but also about leveraging their connections to infiltrate other businesses. Because these IT providers have access to various systems, a breach there could cascade, affecting multiple businesses down the line.
Significance of Working Patterns
The hacking activities were noted to align with Chinese business hours, offering more clues about their origins. Moreover, the methods they used showed similarities with past Chinese cyber espionage tactics.
Catching the Cybercriminals
Fortunately, the intrusion was detected and stopped before the hackers could steal any data, thanks to vigilant cybersecurity measures. This highlights the importance of staying vigilant and having robust security protocols in place to protect your business from such threats.
Lessons for Entrepreneurs and Small Business Owners
This incident underscores the pressing need for strong cybersecurity defenses, especially if you use popular tools like Visual Studio Code. Like a lock on your front door, you need to ensure your digital doors are secure to prevent hackers from sneaking in and causing potential harm to your business and your clients’ businesses.

Conclusion
Operation Digital Eye serves as a cautionary tale for entrepreneurs and small business owners about how vulnerabilities in trusted tools can be exploited by cybercriminals. By understanding these risks and strengthening your cybersecurity measures, you can protect your business from becoming the next target. Stay informed and vigilant, as effective security is not just about having the latest technology but also about being aware and prepared for potential threats.
