MITRE ATT&CK

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

The sample is a Microsoft Office document containing VBA macros. Heuristics indicate the presence of CreateObject and CallByName functions, commonly used for executing malicious code. The VBA macros are heavily obfuscated, making it difficult to determine the exact payload, but the presence of these functions strongly suggests an attempt to download and execute a second-stage payload. The document body contains JavaScript-like obfuscated code, further supporting the malicious intent.

Heuristics 4

CreateObject call high OLE_VBA_CREATEOBJ

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.
