MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File T1059.005 Visual Basic

The sample contains a VBA macro that is automatically executed upon opening the document. This macro utilizes PowerShell to download and execute a file from the URL https://mine.yubarajshrestha.info.np/vnxwcry.exe. The presence of the Document_Open macro and the explicit call to PowerShell indicate a clear intent to deliver a secondary payload.

Heuristics 7

Reference to PowerShell high SC_STR_POWERSHELL

Reference to PowerShell
Document_Open macro high OLE_VBA_DOCOPEN

Document_Open macro
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC

Compiled 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.
Visible LOLBin command execution instruction high SE_LOLBIN_RUN_COMMAND

Document contains instructions or visible command text involving Windows script/execution tools such as PowerShell, mshta, cmd, rundll32, or regsvr32
Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
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.
