MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF document contains a link farm with numerous external URLs, a common tactic for SEO poisoning or redirecting users to malicious sites. The document body, though heavily obfuscated, contains references to "Easter lessons for toddlers" and embedded URLs, suggesting a lure to disguise the malicious intent. The presence of multiple PDF_SEO_LINK_FARM heuristics indicates a deliberate attempt to create a large number of links for search engine optimization purposes, likely to distribute malware or phishing content.

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.
