MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The sample is a malicious Office document containing a VBA macro that executes upon opening. The macro attempts to infect the Normal template and other open documents, indicating a self-spreading or persistence mechanism. ClamAV detection as 'Doc.Trojan.Thus-10' further confirms its malicious nature.

Heuristics 5

ClamAV: Doc.Trojan.Thus-10 critical CLAMAV_DETECTION
