MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document contains a large number of embedded links, many of which are SEO-optimized and point to sites offering free in-game currency or items for games like Coin Master and Roblox. The primary URL, http://netcdn.co/app/406889139/coin-master-heaven-daily-free-spins-link-today-game-hack, is likely a lure for phishing or a scam. The presence of numerous external links suggests a link farm or a method to distribute malicious content indirectly.
