MITRE ATT&CK

T1566.001 Spearphishing Attachment T1059.005 Visual Basic T1105 Ingress Tool Transfer T1218.007 Client Execution: Bitsadmin

The sample is an Excel document with a high-confidence heuristic firing for macro usage and a lure to enable content. It also references Windows Script Host and bitsadmin, indicating a likely download and execution chain. The embedded URL `http://www.mva.by/tags/scan_ctm_req.exe` is likely the second-stage payload.

Heuristics 5

Reference to Windows Script Host high SC_STR_WSCRIPT

Reference to Windows Script Host
Reference to bitsadmin (download) high SC_STR_BITSADMIN

Reference to bitsadmin (download)
LOLBin token sequence in document text high SE_LOLBIN_RUN_COMMAND

Extracted document text contains a Windows script/execution tool name (PowerShell, mshta, cmd, rundll32, regsvr32, …) within 220 characters of a dangerous flag, command verb, or URL. This is a visible 'run this' instruction in HTML/PDF/RTF lure bodies, or — in macro-laden Office files — the macro's own string-pool entries appearing adjacent in extracted text.
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 — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
