The critical ClamAV detection and high-severity heuristics for VBA macros, Workbook_Open execution, and CreateObject point to a malicious downloader. The Workbook_Open macro executes a batch script by reconstructing the command: 'c:\programdata\jledshf.bat'. This batch script, in turn, attempts to download a payload from multiple URLs, including 'http://actividades.laforet.com/wp-admin/BlkdOKDXL/', and executes it. The presence of Wscript.Shell and CreateObject calls further supports the execution of external commands and scripts.

  • Reference to Windows Script Host high SC_STR_WSCRIPT
    Reference to Windows Script Host
  • Workbook_Open macro high OLE_VBA_WBOPEN
    Workbook_Open macro
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject call
  • 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
