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

The PDF file exhibits characteristics of a link farm, with numerous embedded URLs pointing to external resources. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and the 'PDF_SEO_LINK_FARM' heuristic strongly suggest a phishing or malware distribution intent. The document body contains a large number of these URLs, with http://pavaxip.dom-gleden.icu/uploads/2020/01/27/perijo.pdf being the first listed and a primary indicator.
