MITRE ATT&CK

T1059.005 Visual Basic T1059.003 Windows Command Shell

The PowerPoint file contains VBA macros, including an Auto_Close macro, which is designed to execute malicious code. The macros utilize WScript.Shell and the Shell() function, indicating an attempt to run arbitrary commands or download and execute a second-stage payload. The presence of these critical heuristics strongly suggests a macro-based attack. No specific family could be identified.

Heuristics 9

Shell() call in VBA critical OLE_VBA_SHELL

Shell() call in VBA
WScript.Shell usage critical OLE_VBA_WSCRIPT

WScript.Shell usage
Reference to Windows Script Host high SC_STR_WSCRIPT

Reference to Windows Script Host
Auto_Close macro high OLE_VBA_AUTOCLOSE

Auto_Close macro
CreateObject call high OLE_VBA_CREATEOBJ

CreateObject call
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.
VBA macros detected medium OLE_VBA_MACROS

Document contains VBA macro code
Suspicious extracted artifact medium 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.
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.
