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

The PDF document contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic, which is indicative of a phishing or malware distribution campaign. The ClamAV detection further supports its malicious nature. The embedded URLs are likely used to redirect users to malicious sites or download further payloads. The document body, though partially corrupted, contains text related to formal emails, suggesting a potential social engineering lure.

  • 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.
