MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment

The PDF employs an image-only lure, a common phishing tactic where a screenshot masks clickable elements. Heuristics confirm this, specifically identifying an 'escaped URI' pointing to 'https://flowersaffairs.com/nece/?DdOuaPKCcKcQPWqKykzHCzDrvDfFTJIMwPujqbaZVeOpHUtenkstHGYMUOocj'. This URL is the primary indicator of malicious intent, likely leading to a phishing page or malware download.

Heuristics 2

  • Image-heavy PDF hides clickable URL with PDF string escapes high PDF_ESCAPED_URI_IMAGE_LURE
    PDF is image-heavy with little real text and its clickable HTTP(S) URI is encoded with PDF octal escapes. This combination is common in credential-phishing PDFs that render a screenshot-like prompt and obscure the destination from simple URL extractors.
  • 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 200 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
