MITRE ATT&CK

T1566.001 Phishing: Spearphishing Attachment T1059.001 Command and Scripting Interpreter: PowerShell

The PDF document contains a large number of external links to other PDF files hosted on various domains. This pattern is indicative of a link farm or SEO abuse, likely intended to generate traffic or ad revenue. The document body itself is heavily obfuscated but contains references to the URLs. No scripts were extracted from this sample.

Heuristics 3

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
External URI info PDF_URI

PDF contains an external URL action
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.
