MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs, including one that directly links to a potential download. The ML classifier strongly flagged this PDF as malicious, and the presence of a visual download button lure further supports a malicious intent. The document's content and embedded links suggest a phishing attempt to trick users into downloading malware disguised as game cheats or currency generators for Roblox.
