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

The PDF contains a large number of embedded links to other PDF files, a technique often used for SEO poisoning or to distribute malicious content. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and the ML classifier output strongly indicate malicious intent. The document body, though partially corrupted, contains references to 'Dynamic safety stock calculation in excel' and includes URLs that are part of a link farm, suggesting a lure to download further malicious content.
