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

The PDF document contains a lure for "Betet result 2011 pdf download" and exhibits a PDF link farm heuristic, indicating it's designed to redirect users to external malicious content. Numerous URLs were extracted, suggesting a broad distribution effort. The document body text, though partially obfuscated, contains references to these URLs and the download lure.

Heuristics 4

  • 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.
  • Fake invoice / payment lure low SE_INVOICE_LURE
    Document contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
  • 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.
