Unsigned .node File Loaded
Detects the loading of unsigned .node files. Adversaries may abuse a lack of .node integrity checking to execute arbitrary code inside of trusted applications such as Slack. .node files are native add-ons for Electron-based applications, which are commonly used for desktop applications like Slack, Discord, and Visual Studio Code. This technique has been observed in the DripLoader malware, which uses unsigned .node files to load malicious native code into Electron applications.
