MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a primary external URI pointing to a download for a "gg-hack-client-roblox-game-hack". The ML classifier strongly flagged this PDF as malicious, and the presence of download-related lures reinforces the phishing and potential malware distribution intent. No scripts were extracted, but the embedded links suggest the document is designed to trick users into downloading and executing a second-stage payload.
