T1566.001 Spearphishing Attachment
The PDF document contains numerous links to external websites, many of which are hosted on zephyrtoys.com and appear to be part of a link farm designed to attract users searching for game cheats and hacks. The primary URL http://netcdn.co/app/431946152/roblox-hack-smurf-backpack-game-hack suggests a download lure. The presence of a PDF_SEO_LINK_FARM heuristic firing further supports the assessment of a malicious link distribution scheme.
