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

The PDF contains multiple URLs pointing to files related to Roblox hacks, suggesting a lure to download potentially malicious content. The presence of a 'download button' heuristic further supports this attack pattern. The ML classifier also flagged the PDF as malicious with high confidence.
