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

The PDF document contains embedded URLs and text that promote free Robux and game hacks, acting as a lure for users to click on malicious links. The ML classifier strongly flagged this PDF as malicious, and the presence of a download button heuristic further supports a malicious intent to trick users into downloading unwanted content. The primary IOC is the external URI pointing to a suspicious domain.
