File-based attack

Refers to an attack where threat actors use certain file types, usually those bearing document file extensions like .DOCX and .PDF, to entice users to open them. The file in question has been embedded with a malicious code (malcode); thus, once opened, this code is also executed. Usually, the malcode delivers an equally malicious payload.

Below are other file types used in malicious attacks:

  • Binary executables: EXE, DLL, MSI
  • Scripts: JS, VBS, PowerShell
