MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains a SE_INVOICE_LURE heuristic, indicating it is designed as a fake invoice to trick the user. It also embeds a URL, http://diaoc365.xyz/Document/US_us/Invoice-receipt, which is likely used to deliver a secondary payload. The ClamAV detection 'Pdf.Dropper.Agent-7296669-0' further confirms its malicious nature as a dropper.
