MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment T1059.001 Command and Scripting Interpreter: PowerShell

The PDF file contains a large number of embedded URLs pointing to other PDF files hosted on various domains. This behavior is indicative of a link farm or a distribution mechanism for malicious content, as suggested by the 'PDF_SEO_LINK_FARM' heuristic and ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0'. The document body itself contains a mix of legitimate-sounding text and the list of URLs, reinforcing the phishing or content distribution intent.

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.
