T1566.001 Phishing: Spearphishing Attachment T1204.002 Malicious File: Malicious Link

The PDF file contains a large number of embedded URLs, identified as a 'PDF_SEO_LINK_FARM' heuristic. These URLs likely lead to further malicious content, such as phishing pages or malware downloads. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports the phishing and malicious intent. No scripts were extracted from this sample.
