MITRE ATT&CK

T1059.005 Visual Basic for Applications T1204.002 Malicious File

The presence of Excel 4.0 (XLM) macros, specifically an Auto_Open defined name, indicates an attempt to automatically execute code upon opening the document. The heuristic 'SE_ENABLE_LURE' suggests the document prompts the user to enable macros, a common social engineering tactic. The extracted URLs are likely used to download and execute further stages of the attack. The confidence is slightly reduced due to the lack of script content to directly analyze the payload.

Heuristics 4

Excel 4.0 Auto_Open defined name critical OLE_XLM_AUTOOPEN_DEFINEDNAME

oletools 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_AUTOOPEN

Workbook 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_LURE

Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — context-specific rules above attribute URLs they actually evaluated; this rule lists URLs that were present in the bytes but were not otherwise tied to a specific finding.
