About the issue​

Development extensions are commonly used by software developers to extend the functionality of integrated development environments, code editors, and other developer tools. Extensions are typically distributed through public marketplaces as packages that bundle the extension code with supporting resources. Development extension code implements behaviors that integrate it with the host application. This integration allows extensions to register commands, react to editor events, or provide programming language support. Extension code is loaded and executed automatically by the host application during events such as editor startup, file opening, or user interaction. These events are used by extension developers to set up the environment for nominal extension use, or to respond to activity within the host application. It is unusual for certain types of development extensions to execute commands that can collect sensitive system files. Attackers often abuse development extensions to run commands that collect authentication details such as tokens and credentials, private keys, environment files, and other secrets that could help them gain unauthorized access to the system on which their malicious code was loaded.

How to resolve the issue​

  • Investigate reported detections.
  • Consult Mitre ATT&CK documentation: T1176.002 - Software Extensions: IDE Extensions.
  • If the development extension intent does not relate to the reported behavior, investigate your development environment for software supply chain compromise.
  • You should stop using the development extension until the investigation is completed, or until the issue is risk accepted.
  • Consider replacing the development extension with an alternative.
