MITRE ATT&CK

T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file was flagged by a machine learning classifier as malicious and contains a large number of embedded external links. The heuristic 'PDF_SEO_LINK_FARM' indicates that the document is designed to host a mass of external links, likely to manipulate search engine results or distribute malicious content. No scripts were extracted from this sample, and the document body was unreadable, so the attack pattern is inferred from the link farm heuristic.

Heuristics 2

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.
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.
