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

The PDF document contains a large number of embedded external links, a technique often used for SEO poisoning or to direct users to malicious sites. The document body, though partially corrupted, suggests a lure related to job offers. The heuristic 'PDF_SEO_LINK_FARM' specifically indicates a mass of external links generated for SEO purposes, pointing towards a malicious intent to drive traffic to potentially compromised or malicious domains.
