MITRE ATT&CK

T1059.001 PowerShell T1218.005 Client Execution: Mshta

The PowerPoint file contains a VBA macro with an Auto_Open subroutine. This macro utilizes a Shell() call and references mshta.exe, indicating an attempt to execute external commands. The presence of the 'SE_LOLBIN_RUN_COMMAND' heuristic further supports the use of mshta.exe to execute a command from the document body. The reconstructed command likely involves downloading and executing a second-stage payload from the embedded URL.

Heuristics 8

Shell() call in VBA critical OLE_VBA_SHELL

Shell() call in VBA
Reference to mshta.exe high SC_STR_MSHTA

Reference to mshta.exe
Auto_Open macro high OLE_VBA_AUTO

Auto_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.
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.
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.
