MITRE ATT&CK

T1566.001 Phishing:Spearphishing Attachment T1204.002 Malicious Link

This PDF document contains a large number of embedded external links, a technique commonly used to create SEO link farms. The document body itself is minimal, containing only a title and metadata, suggesting its primary purpose is to host these links. The heuristic firings confirm the presence of a link farm and external URIs, indicating the document is designed to redirect users to a network of potentially malicious websites.
