MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites, many of which are hosted on `netcdn.co` and `polycraft.ae`, and promise free in-game currency or hacks. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs and a call-to-action button suggests an attempt to trick users into downloading or visiting malicious sites. No scripts were extracted from this sample, but the overall pattern is consistent with a phishing or malware distribution lure.
