MITRE ATT&CK
T1566.002 Phishing: Spearphishing Link T1204.001 User Execution: Malicious Link

The sample is a small PDF containing a high volume of external links to other PDFs on disparate domains, which is characteristic of an SEO link farm. The document body contains a lure related to a 'Fashion company business plan pdf', and the ClamAV detection 'Pdf.Phishing.TtraffRobotInstall' further supports the phishing nature of the sample.
