T1566.001 Spearphishing Attachment
T1204.001 User Execution: Malicious Link
The PDF document contains a large number of external links, many of which point to SEO-optimized PDF files hosted on potentially malicious domains. The presence of a fake CAPTCHA heuristic suggests the document is designed to trick users into interacting with these links. The primary URL, https://netcdn.xyz/app/406889139/2021-free-spins-on-coin-master-game-hack, is likely the initial lure, leading to further malicious content.
