VBScript dropper distributed via WhatsApp Web targeting corporate users. Observed in the wild 2026-06-18.

UAC bypass via ConsentPromptBehaviorAdmin=0 (16x loop via ShellExecute runas)

LOLBin masquerade (curl.exe renamed ntdll.dll, bitsadmin.exe renamed kernel32.dll)

stage-2 download from Backblaze B2 (f005.backblazeb2.com/file/baxihaoa/baosduoa.zip) with certutil/bitsadmin/curl fallback chain, self-deletion via ping delay.

Consistent with Microsoft Defender WhatsApp VBS campaign (Feb-Apr 2026).

Prevented by EDR. Host: Windows 11 workstation, healthcare sector Brazil.
