Detected macro logic that will automatically execute on document open. Most malware contains some execution hook.

Macro with File System Write

Detected macro logic that can write data to the file system.

Macro Execution Coercion

Detected a document that appears to social engineer the user into activating embedded logic.

Macro Contains Suspicious String

Detected a macro with a suspicious string. Suspicious strings include privileged function calls, obfuscations, odd registry keys, etc...

Macro with DLL Reference
