MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains an embedded URI pointing to a suspicious domain, disguised as a 'Ryanair boarding pass' search. ClamAV and ML classifiers flagged this file as malicious, indicating a phishing or trojan-like behavior. Although no scripts were explicitly extracted, the presence of external URIs and the nature of the embedded text suggest an attempt to redirect the user to a malicious site for credential harvesting or malware delivery.
