Israeli Researchers Uncover Malicious Add-Ons Threatening Organizations Worldwide
A group of Israeli researchers has uncovered significant security vulnerabilities within the Visual Studio Code (VSCode) Marketplace, revealing that malicious extensions have infiltrated over 100 organizations. By trojanizing a popular theme, Dracula Official, the researchers demonstrated how easily risky code can be embedded. Their findings indicate the presence of thousands of dangerous extensions with millions of installations.
Visual Studio Code, a widely-used source code editor published by Microsoft, offers an extensive marketplace for extensions that enhance its functionality. However, previous reports have highlighted critical security gaps within this marketplace. Issues such as extension and publisher impersonation and theft of developer authentication tokens have been confirmed, exacerbating the risks.
The researchers emphasized the severity of the problem, stating, "VSCode extensions are an abused and exposed attack vertical, with zero visibility, high impact, and high risk. This issue poses a direct threat to organizations and deserves the security community’s attention."
Microsoft's current lack of stringent controls and code review mechanisms on the VSCode Marketplace has allowed threat actors to exploit the platform extensively. Despite responsible reporting of the malicious extensions to Microsoft, most remain available for download.
In response to this alarming situation, the researchers plan to release 'ExtensionTotal,' a free tool designed to help developers scan their environments for potential threats. This tool, along with details about its operational capabilities, will be published next week.
