MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains numerous embedded links designed to appear as helpful resources for popular games, but they lead to external sites. The heuristic findings indicate a PDF link farm and a malicious ML classification, strongly suggesting these links are part of a scam or phishing attempt to redirect users to malicious content. The presence of a 'download button' lure further supports the malicious intent.

Heuristics 4

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow

PDF contains an external URL action
Embedded URL info EMBEDDED_URL
