MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF is identified as malicious by ClamAV and an ML classifier, and exhibits characteristics of a phishing lure due to its image-heavy nature and a single clickable action. The embedded URL, https://trafffi.ru/aws?keyword=cod+black+ops+zombies+apk+pure, is likely the destination for the user's interaction, aiming to deliver a malicious payload or phish for credentials. No scripts were extracted, but the PDF structure itself suggests a malicious intent.
