MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a large number of external links, a technique often used for SEO spam or to redirect users to malicious sites. The document body mentions "how to jailbreak ipod touch 4 without computer", which appears to be a lure to attract clicks. The heuristic PDF_SEO_LINK_FARM strongly indicates this is a link farm designed to manipulate search engine results or distribute traffic to numerous unrelated sites.

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.

  • Embedded URL info EMBEDDED_URL
