MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File

The sample is a Microsoft Word document containing VBA macros. The document body suggests a financial lure, and the 'SE_PASSWORD_ARCHIVE_LURE' heuristic indicates it may instruct the user to decrypt a password-protected archive, a common tactic to evade gateway scanning. The presence of VBA macros and a 'macros.bas' file strongly suggests the execution of malicious code via Visual Basic. The 'SC_STR_WSCRIPT' heuristic further supports the execution of scripts.

Heuristics 7

Heap-spray pattern detected high SC_HEAP_SPRAY

Repeated 0x41 (A) bytes found
Reference to Windows Script Host high SC_STR_WSCRIPT

Reference to Windows Script Host
CreateObject call high OLE_VBA_CREATEOBJ

CreateObject call
Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE

Document gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
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.
