T1059.005 Visual Basic
T1566.001 Spearphishing Attachment
The sample contains VBA macros that are configured to auto-execute upon opening, specifically using the 'Document_Open' event to call the 'Shell' function. This indicates a dropper functionality. The heuristic 'SE_MFA_LURE' suggests the document's content is designed to trick users into approving multi-factor authentication requests or providing one-time codes, aligning with credential harvesting tactics. The ClamAV detection 'Doc.Dropper.ZwMacros-6057750-0' further confirms its malicious nature as a macro-based dropper.
Heuristics 5
-
ClamAV: Doc.Dropper.ZwMacros-6057750-0 critical CLAMAV_DETECTIONClamAV detected this file as malware: Doc.Dropper.ZwMacros-6057750-0
-
MFA / one-time-code harvesting lure high SE_MFA_LUREDocument asks for a one-time code, authenticator approval, or MFA confirmation — consistent with credential phishing kits that steal session tokens or abuse multi-factor authentication
-
VBA macros detected medium 1 related finding OLE_VBA_MACROSDocument contains VBA macro code
-
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXECCompiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL http://ns.adobe.com/xap/1.0/ In document text (OLE body)
