T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document contains numerous embedded links, many of which are related to game hacks and cheats, suggesting a lure for users to download malicious content. The presence of a "download button" heuristic further supports this. The ML classifier also strongly indicated maliciousness. No scripts were extracted from this sample, but the overall structure and embedded links point to a phishing or social engineering attack.
