MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual lure suggesting a download. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs points towards a potential download or redirection to a malicious site. While no scripts were explicitly extracted, the PDF structure and embedded content suggest it's designed to trick users into downloading further malicious content, likely related to game cheats or hacks.
