MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF contains a large number of external links, many of which point to other PDF files, indicating a link farm designed to distribute malicious content. The document body, despite being partially corrupted, mentions 'Android won't install google play services', likely a lure to trick users into clicking the embedded links. ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports the phishing and malicious distribution intent.

  • 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.
