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

The PDF document contains a large number of external links, many of which are hosted on domains that appear to be part of a link farm. The document body mentions 'Tropical smoothie cafe job requirements', suggesting a lure to entice users to click on these malicious links. The primary attack pattern involves redirecting users to a network of compromised websites, likely for further exploitation or phishing.

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.
