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

The sample contains VBA macros that are automatically executed upon opening the document via the Document_Open subroutine. These macros utilize the Shell() function to execute ping commands targeting several suspicious domains: innocentangels.com, whitesonly.net, kkk.com, and daddysgirl.com. This indicates an attempt to download or connect to malicious infrastructure.

Heuristics 5

  • ClamAV: Doc.Trojan.Ping-6 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.Ping-6
  • VBA macros detected medium 3 related findings OLE_VBA_MACROS
    Document contains VBA macro code
  • Shell() call in VBA critical OLE_VBA_SHELL
    Shell() call in VBA
  • 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.
