MITRE ATT&CK

T1204.002 Malicious File: User Execution: Malicious File T1059.003 Command and Scripting Interpreter: Windows Command Shell T1566.001 Phishing: Spearphishing Attachment

The sample contains VBA macros with an AutoOpen subroutine. This subroutine constructs and executes a command to launch Microsoft Edge and navigate to a specific YouTube URL. The document body contains text instructing the user to enable editing and content, which is a common lure to bypass macro security. The executed command is 'start microsoft-edge:https://www.youtube.com/watch?v=dQw4w9WgXcQ'.

Heuristics 9

Shell() call in VBA critical OLE_VBA_SHELL

Shell() call in VBA
Suspicious cmd.exe invocation with execution flag high SC_STR_CMD

Suspicious cmd.exe invocation with execution flag
AutoOpen macro high OLE_VBA_AUTOOPEN

AutoOpen macro
cmd.exe reference in VBA high OLE_VBA_CMD

cmd.exe reference in VBA
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.
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
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.
