MITRE ATT&CK
T1204.002 Malicious File Execution: Malicious File T1059.005 Command and Scripting Interpreter: Visual Basic T1059.001 Command and Scripting Interpreter: PowerShell

The sample is an OLE document containing VBA macros that trigger a Shell() call and a CreateObject call, indicating an attempt to execute external code. The presence of a CVE-2015-0097 heuristic firing suggests exploitation of this specific vulnerability. The embedded URLs are likely used to download and execute a secondary payload. The document body is heavily obfuscated and unreadable, providing no direct clues to the user-facing lure.

  • Shell() call in VBA critical OLE_VBA_SHELL
    Shell() call in VBA
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject call
  • Visible LOLBin command execution instruction high SE_LOLBIN_RUN_COMMAND
    Document contains instructions or visible command text involving Windows script/execution tools such as PowerShell, mshta, cmd, rundll32, or regsvr32
  • 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
