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

The PDF file contains a significant number of embedded external links, identified as a PDF SEO link farm. The primary purpose appears to be directing users to a large collection of other PDF documents hosted on various domains. One of the embedded URLs is http://thetravelbucket.net/uploads/1/3/0/3/130313320/130313320.html#baby+doll+dj+song++pagalworld, which is also present in the document body. This suggests a coordinated effort to manipulate search engine results or distribute potentially harmful content through a network of linked pages.

Heuristics 3

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
