MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs that lead to a suspicious domain, likely serving as a lure for downloading malware. The critical heuristic 'SE_VIRAL_VIDEO_CLICKBAIT_LINK' indicates the document is designed to trick users into clicking on links related to popular search terms, such as service manuals, to download malicious content. The presence of multiple CDN links and a direct link to a suspicious URL suggests a downloader or redirector pattern.

Heuristics 4

  • Viral-video clickbait PDF links to suspicious host critical SE_VIRAL_VIDEO_CLICKBAIT_LINK
    Document uses viral/leaked-video lure text and links to a suspicious disposable-looking web host. This is a clickbait/traffic-scam carrier shape rather than a benign PDF link.
  • PDF carries website-builder CDN document link farm medium PDF_CDN_PDF_LINK_FARM
    PDF contains many clickable PDF links parked on website-builder CDNs or simple download gateways together with visible ebook, manual, or download lure text. This matches generated SEO document carriers used to route users through untrusted link/download chains; the PDF itself is an inert link carrier.
  • 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.
