Attention: We have transitioned to a new AAD or Microsoft Entra ID from the week of May 20, 2024. In case your tenant requires admin consent, please refer to this document located at Overview of user and admin consent - Microsoft Entra ID | Microsoft Learn and grant access to App ID: 6ba09155-cb24-475b-b24f-b4e28fc74365 with graph permissions for Directory.Read.All and User.Read for continued access. While the app may appear unverified, you can confirm its legitimacy by verifying the App ID provided.
We're gradually updating threat actor names in our reports to align with the new weather-themed taxonomy. Learn about Microsoft threat actor names

Summary
VirTool:Win32/VBInject.DN is a detection for an obfuscator wrapper used by malicious executables. The malicious executable is usually encrypted/compressed and stored inside the wrapper. When executed, it decodes the malicious executable and injects it into a clean process, for example, "explorer.exe", or loads it into a new process of its own.
Manual removal is not recommended for this threat. To detect and remove this threat and other malicious software that may have been installed, run a full-system scan with an up-to-date antivirus product such as Microsoft Security Essentials, or the Microsoft Safety Scanner.
