Cybersecurity researcher Mazin Ahmed discovered that attackers are exploiting VS Code and AI-powered IDEs like Cursor AI by publishing malicious extensions that bypass security screening. A fake Python linter called "Piithon-linter" successfully made it through Microsoft's marketplace security checks and could steal developer credentials and deploy remote access tools. The malware activates automatically when VS Code launches, first checking for antivirus software before harvesting sensitive environment variables. It uses geofencing to avoid detection during Microsoft's sandbox testing and can target Windows, macOS, or Linux systems. Most concerning is that OpenVSX marketplace, which powers Cursor AI, performs virtually no security verification. Since developers have access to source code, credentials, and production systems, these compromised extensions could lead to major supply chain attacks targeting entire organizations. **Source:** [Cybersecurity News](https://cybersecuritynews.com/hackers-compromising-developers-with-malicious-vs-code/)
