MITRE ATT&CK

T1059.005 Visual Basic

The file contains a Workbook_Open VBA macro, which is a common technique for executing malicious code upon opening the document. The macro source is obfuscated, and a suspicious artifact named 'macros.bas' was extracted. The document body appears to be a form for job data, but the presence of the macro and obfuscated code suggests it's a lure for executing malware. No specific family could be identified.

Heuristics 4

Workbook_Open macro high OLE_VBA_WBOPEN

Workbook_Open macro
Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGE

VBA macros detected medium OLE_VBA_MACROS

Document contains VBA macro code
Embedded URL info EMBEDDED_URL

One 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.
