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

The PDF file contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic, suggesting a link farm or phishing attempt. The SE_INVOICE_LURE heuristic indicates the document may be disguised as an invoice or payment request. The ClamAV detection further confirms its malicious nature. The primary attack pattern involves luring the user to click on one of the numerous embedded URLs, which likely lead to 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.
