The PDF file contains a large number of embedded links, many of which point to a redirector service (ttraff.com). The document body text is garbled but appears to contain keywords related to 'sheet metal fabrication company in pune', suggesting a lure to trick users into clicking the malicious links. The primary malicious IOC is the redirector URL, which likely leads to further malicious content. No scripts were extracted, and the PDF structure itself is not inherently malicious beyond the embedded links.

Heuristics 3

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
  • 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.
