MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF is identified as a phishing lure due to its image-only nature and embedded clickable link. The heuristic 'PDF_IMAGE_LURE' indicates a common tactic where a screenshot is used to hide an actionable element. The embedded URL, https://fokemale.ru/aws?utm_term=common+core+standards+kindergarten+speaking+and+listening, is the primary indicator of a potential phishing or malicious download site.

Heuristics 5

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

    PDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 50 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.

    PDF contains an external URL action

    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.
