MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

This PDF document contains a large number of external links, many of which point to other PDF files hosted on the same domain, suggesting a link farm or redirection scheme. The document body and heuristics indicate a lure for game-related hacks and free in-game currency, likely to trick users into downloading malware or visiting malicious sites. The ML classifier strongly supports the malicious verdict.
