T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The PDF document contains numerous embedded URLs that are presented as links to game cheats and hacks, indicating a lure to download malicious content. The heuristic PDF_SEO_LINK_FARM firing suggests a large number of these links are present, and the ML_NYX_PDF_MALICIOUS model strongly flagged the file. The presence of a 'download button' heuristic further supports the malicious intent.
