MITRE ATT&CK

T1566.002 Spearphishing Attachment T1059.001 PowerShell T1204.002 Malicious Link

The PDF contains embedded JavaScript and a critical heuristic firing for a malicious redirector link. The document body, though heavily obfuscated, contains text that, combined with the heuristic, strongly suggests an advance-fee scam lure. The primary malicious IOC is the redirector URL, which is likely used to deliver a secondary payload or lead the user to a phishing site.

Heuristics 4

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.
Advance-fee lottery/parcel scam lure high SE_ADVANCE_FEE_SCAM_LURE

Document contains lottery/beneficiary or prize language together with large-value draft/funds wording and parcel/courier delivery requirements. This is a classic advance-fee fraud document shape.
Embedded JS stream low PDF_JS

PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
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.
