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

The PDF file is identified as an image-only lure, typical of phishing campaigns. It contains numerous external links, with a primary link pointing to 'http://tumekiadaniels.net/uploads/1/3/0/5/130550755/130550755.html#commentary+1+thessalonians+3'. The heuristic 'PDF_SEO_LINK_FARM' indicates a large number of generated links, suggesting an attempt to manipulate search engine results or distribute malicious content across multiple domains. The document body is heavily obfuscated but contains references to the primary URL, reinforcing the phishing lure.

Heuristics 4

  • 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.
  • Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE
    PDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 26 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
  • 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.
