MITRE ATT&CK

T1559.002 Component Object Model Hijacking T1204.002 Malicious File

The PDF contains embedded Flash content, indicated by the PDF_RICHMEDIA and PDF_EMBEDDED heuristics. The embedded file is named 'exploit.swf', strongly suggesting its malicious intent. This type of embedding is often used to deliver exploits targeting Flash Player vulnerabilities or to host further stages of an attack. No JavaScript or VBA scripts were extracted, limiting the analysis of direct execution methods.
