MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs, including one pointing to 'netcdn.co', which are likely intended to redirect users to download malicious payloads or visit phishing sites. The ML classifier strongly flagged this PDF as malicious, and the presence of a visual download button lure further supports a malicious intent. No scripts were extracted from this sample, but the overall structure and embedded URLs suggest a downloader or phishing campaign.
