MITRE ATT&CK

T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

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 designed to attract users with promises of game hacks and free in-game currency. The ML classifier strongly flagged this PDF as malicious, and the presence of a download button lure further supports a malicious intent to trick users into downloading potentially harmful content. The primary attack pattern involves using deceptive content to encourage the download of further malicious payloads.
