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

The PDF document contains a large number of embedded links to external websites, a technique commonly used for SEO poisoning or to redirect users to malicious content. The document body, while partially obfuscated, contains the phrase 'Que es la propilenglicol' and references 'wkhtmltopdf', suggesting a lure related to chemical information. The primary attack vector appears to be directing users to a network of linked PDF files hosted on various domains, likely to distribute further malware or engage in phishing.

Heuristics 3

  • 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.
  • 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.
