MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a fake CAPTCHA lure, designed to deceive users into interacting with a malicious link. The primary external URI points to a URL that suggests a game hack, further supporting the lure. The document body and embedded links contain multiple URLs, one of which is the main indicator of the attack pattern.
