Heuristics 4

Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE

Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
External URI info PDF_URI
