MITRE ATT&CK
T1059.005 Visual Basic
T1203 Exploitation for Client Execution
The sample contains VBA macros that are triggered by the Auto_Close event. These macros construct a URL 'http:// @j.mp/asasdaxaeeedxaskasddkaos' and a command 'mshta '. The `CreateObject` function is used to instantiate a `WScript.Shell` object, which then executes the constructed command and URL, likely to download and execute a second-stage payload. The use of `CreateObject` and `Shell` execution points to a malicious intent to compromise the system.

Neither token alone fires it — it is the pairing that flags p-code-only or source-extraction-failure macro documents where the visible VBA source is unavailable. The matched tokens are named in the detail line below.
