MITRE ATT&CK

T1204.001 Malicious Link T1566.002 Spearphishing Attachment

The PDF contains a critical heuristic firing for a malicious redirector link. The document body, though heavily obfuscated, contains the same URL. A low-signal heuristic for a 'download button' further supports the lure mechanism. The primary IOC is the malicious redirector URL.

Heuristics 3

PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
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
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
