MITRE ATT&CK
T1204.002 Malicious Link

The PDF file is identified as a malicious phishing lure due to its image-heavy nature and the presence of a direct link to a payload. The heuristic PDF_IMAGE_LURE indicates a common tactic where a visual deception hides a clickable element. The critical PDF_DIRECT_PAYLOAD_LINK heuristic confirms that the embedded URL, https://webmail.une.net.co/home/info@serviciosylogisticaha.com.co/Briefcase/Factura-Digital.7z?disp=a&ver=1, directly leads to a downloadable archive, likely containing malware.

Heuristics 3

  • PDF link points directly to executable/archive payload critical PDF_DIRECT_PAYLOAD_LINK
    PDF contains a clickable HTTP(S) URI whose path ends in an executable, script, shortcut, disk image, or archive extension. Documents can legitimately link to installers, so this is a high-risk delivery indicator rather than a standalone exploit fingerprint.
  • Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE
    PDF has 2 image(s), only 0 text block(s), carries a click-outward action, and is only 253 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
  • 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.
