Win.Trojan.BlackEnd-1 · confidence 95%

MITRE ATT&CK
T1059.005 Visual Basic

The file is identified as a legacy Word document containing a WordBasic AutoOpen macro, a known marker for the BlackEnd virus. The document body explicitly states it is the 'BlackEnd AutoMacro Virus' and mentions its generation with a 'DEMOLITION KIT'. The presence of the AutoOpen macro indicates an attempt to automatically execute malicious code when the document is opened, consistent with the BlackEnd family's known behavior.
