MITRE ATT&CK
T1059.005 Visual Basic T1059.001 PowerShell T1204.002 Malicious File

The sample contains a Document_Open VBA macro that utilizes the Shell() function to execute code. The script iterates through a list of URLs, attempting to download and execute content from them. Specifically, it tries to fetch data from 'https://configure.syscatec.com/tp.php?key=xvnd54' and 'https://apsdighi.estttsec.in/lp.php?key=xvnd54'. The script is designed to execute any non-empty response received from these URLs, indicating a downloader or dropper functionality.

Heuristics 7

  • Shell() call in VBA critical OLE_VBA_SHELL
    Shell() call in VBA
  • Reference to Windows Script Host high SC_STR_WSCRIPT
    Reference to Windows Script Host
  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • 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
  • 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.
    URL https://configure.syscatec.com/tp.php?key=xvnd54
    • https://apsdighi.estttsec.in/lp.php?key=xvnd54
    • http://schemas.openxmlformats.org/drawingml/2006/main
