MITRE ATT&CK

T1566.001 Spearphishing Attachment

This PDF document contains a large number of external links, many of which appear to be part of an SEO link farm. The document body, though partially corrupted, contains a URL that suggests a lure for game-related cheats or hacks. The presence of a "download button" heuristic further supports the idea that the document is designed to trick users into clicking links that likely lead to malicious content or further compromise.
