MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF document contains a large number of external links, many of which point to files related to game hacks and cheats, suggesting a lure for users seeking such content. The primary URL, https://netcdn.xyz/app/406889139/coin-master-hack-2021-app-download-game-hack, likely serves as the initial download point for a malicious payload. The PDF structure and extensive link farm indicate a tactic to attract users through search engines and potentially deliver malware.
