MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links to external PDF files, a technique often used for SEO poisoning or to distribute further malicious content. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and the ML classifier output strongly indicate malicious intent. The document body, though heavily obfuscated, contains references to a 'sales commission agreement letter' and 'job offer letter', suggesting a social engineering lure to direct users to the malicious URLs.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • 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.
