MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The document contains multiple embedded URLs and a prominent external URI pointing to a download site, disguised as a guide for hacking Roblox. The ML classifier strongly flagged this PDF as malicious, indicating a high probability of it serving a malicious payload or leading to a phishing attempt. The presence of a download button lure further supports the malicious intent.
