The heuristic SE_PAYMENT_REDIRECT_LURE indicates the document's content is designed to trick the user into believing there are new or changed bank instructions. The PDF_URI heuristic reveals an external URL that redirects to a malicious domain hosting a document, likely the payload. ClamAV also detected this as a known dropper. No scripts were extracted from this sample.
