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

The PDF contains a significant number of external links, identified by the PDF_SEO_LINK_FARM heuristic, suggesting a link farm or phishing attempt. One of the embedded URLs, http://find24hs.com/, appears to be a gateway for further malicious activity. The document body was unreadable, but the presence of numerous links strongly indicates a malicious intent to redirect users to potentially harmful sites.
