This article discusses a security flaw in popular AI IDEs like Cursor and Windsurf, which recommended non-existent extensions from Microsoft’s marketplace. The authors proactively claimed vulnerable namespaces on OpenVSX to prevent malicious uploads, securing the environment for developers.

The Glassworm malware campaign has resurfaced with 24 new malicious packages on OpenVSX and the Microsoft Visual Studio Marketplace. This malware uses hidden code to steal developer credentials and cryptocurrency data while providing remote access to attackers. Despite prior containment efforts, it continues to evade detection and reappear on these platforms.

Two harmful extensions on the Visual Studio Code Marketplace, Bitcoin Black and Codo AI, steal sensitive information from developers' machines. They can capture screenshots, credentials, and hijack browser sessions, and were published under the name 'BigBlack.' Microsoft has since removed both extensions from the marketplace.

AI-driven IDEs like Cursor and Google Antigravity recommend extensions that may not exist in the OpenVSX registry. This gap allows malicious actors to claim unregistered namespaces and potentially distribute malware. Researchers have reported the issue and taken steps to prevent exploitation.

A set of ten malicious VSCode extensions on the Microsoft Visual Studio Code Marketplace has been found to infect users with the XMRig cryptominer for Monero. These extensions masquerade as legitimate tools and execute a PowerShell script to install the malware while also disabling critical Windows security features. Microsoft has since removed the extensions and blocked the publisher from the marketplace.

A browser hijacking campaign has infected 2.3 million users of Chrome and Edge through malicious extensions that started as legitimate tools. These extensions, which include features like color pickers and emoji keyboards, were later updated to include malware that tracks user activity and redirects browser sessions. Microsoft has removed the extensions from its store, but Google has not yet responded to the incident.
