MITRE ATT&CK
T1204.002 Malicious File T1059.001 PowerShell T1566.002 Spearphishing Attachment

The PDF document contains a large number of external links, a technique often used to distribute malware or redirect users to malicious sites. One heuristic specifically flagged this as a 'PDF_SEO_LINK_FARM'. Additionally, another heuristic identified a URI pointing directly to an IP address, which is a common evasion technique. The presence of these indicators suggests the document is designed to facilitate the download of further malicious content.

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.
  • Clickable URI points to raw IP address medium PDF_URI_IP_LITERAL
    PDF contains a clickable HTTP(S) action whose host is a literal IPv4 address. Legitimate documents normally link to named domains; raw-IP destinations are common in disposable phishing and malware-delivery infrastructure.
  • 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.
