T1566.001 Spearphishing Attachment
T1059.005 Visual Basic
T1204.002 Malicious File
The sample contains Excel 4.0 macros with an Auto_Open entry, indicating automatic execution upon opening. The document body and heuristics suggest a lure impersonating DocuSign to trick the user into enabling macros. The extracted URLs are likely part of the payload delivery chain. The XLM macros are too truncated to determine the exact execution flow, but the presence of Auto_Open and the lure strongly suggests a downloader or initial access mechanism.
Heuristics 4
-
Excel 4.0 Auto_Open defined name critical OLE_XLM_AUTOOPEN_DEFINEDNAMEoletools recovered an Auto_Open / Auto_Close entry from an Excel 4.0 macro sheet. The raw BIFF name can be tokenized or partially opaque to byte-string checks, but the recovered macro listing confirms the workbook has an XLM auto-execution entry.
-
Excel 4.0 (XLM) macro sheet present medium OLE_XLM_AUTOOPENWorkbook contains an Excel 4.0 macro sheet sub-stream — XLM is rarely seen in modern legitimate workbooks and was a major Office malware vector during 2020-2022.
-
Macro/content-enable lure medium SE_ENABLE_LUREDocument instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
-
Document signing service impersonation lure medium SE_DOCUSIGN_LUREDocument impersonates DocuSign, Adobe Sign, or a similar signing service in a signing-request context
