MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

This PDF file was detected as malicious by ClamAV (Pdf.Dropper.Agent-9253366-0) and an ML classifier. It contains a large number of external links, suggesting a link farm or SEO poisoning tactic. The embedded document body text, though partially corrupted, mentions 'high school incident report form', likely a lure. The primary function appears to be distributing or linking to other malicious content via these numerous URLs.
