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

The PDF document contains numerous external links, a technique often used for SEO poisoning or to redirect users to malicious sites. The document body mentions 'Sniper elite 3 game guide', suggesting a lure to attract clicks. The heuristic 'PDF_SEO_LINK_FARM' confirms the presence of a link farm, indicating a malicious intent to drive traffic to potentially compromised or malicious domains.
