MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded links that point to known malicious redirector infrastructure, specifically targeting users with lures related to game hacks and cheats. The ML classifier also strongly flagged this PDF as malicious. While no scripts were explicitly extracted, the PDF structure itself facilitates the redirection, likely leading to a second-stage download or phishing page.

  • Embedded URL info EMBEDDED_URL
