MITRE ATT&CK

T1566.001 Spearphishing Attachment

This PDF document exhibits characteristics of a malicious lure, likely intended to trick users into downloading malware disguised as game cheats or hacks. The document contains a large number of external links, many of which are SEO-optimized and point to other PDFs, creating a link farm. One prominent URL, http://netcdn.co/app/431946152/noclip-hack-roblox-jailbreak-download-game-hack, suggests a direct download of a potentially harmful file.
