MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious File

The PDF document contains a large number of embedded links, many of which point to external resources offering game hacks and cheats. The ML classifier strongly indicated maliciousness, and the presence of a download button lure reinforces the intent to trick users into downloading further malicious content. The primary URL http://netcdn.co/app/406889139/fbchampion-game-hack is likely a distribution point for a second-stage payload.
