MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file was detected by ClamAV as Pdf.Phishing.TtraffRobotInstall-7605656-0. Static analysis revealed a large number of external links, many of which follow a pattern indicative of SEO link farming or hosting phishing content. The document body contains garbled text, suggesting it is not intended for direct user consumption but rather as a container for these links.

Heuristics 3

    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.
