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

The PDF file contains a large number of embedded URLs, forming a link farm, which is a common technique for SEO poisoning and distributing malicious content. The heuristic 'SE_ADVANCE_FEE_SCAM_LURE' strongly indicates that the document's content is designed to deceive users with fake prize or parcel delivery schemes. The ClamAV detection further confirms its malicious nature. The embedded URLs likely lead to further stages of the attack, such as phishing pages or malware downloads.

  • 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.
