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

The PDF file is identified as a screenshot lure, typical of phishing campaigns. It contains numerous external links, with the primary one being http://ginabugstupperware.com/uploads/1/3/0/9/130969904/130969904.html#pentair+sand+dollar+above+ground+pool+sand+filter+system. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass of generated SEO links, suggesting a broad phishing or spam distribution effort. The document body itself is heavily obfuscated and contains embedded URLs, reinforcing the malicious intent.

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 20 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.
