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

The PDF document contains multiple embedded URLs, with a critical heuristic firing for repeated invisible links designed to deliver a payload. The primary malicious URL identified is http://resumeskayako.site/Free-Annual-Rental-History-Report/pdf/yourexperiencesmatter.com. The document body itself contains a mix of URLs and what appears to be obfuscated or corrupted text, further indicating a malicious intent to redirect the user to a compromised site for payload delivery.

Heuristics 2

  • Invisible/repeated PDF links deliver payload file critical PDF_REPEATED_PAYLOAD_LINK_LURE
    PDF uses invisible link annotations and points to a direct payload download. Repeated invisible links or lure-like payload names such as document/unlock/verify archives match malware-delivery PDF carriers where the page is only a prompt and the real payload is fetched from the linked 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.
