MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF is identified as an image-only lure, typical for phishing attacks. It contains an embedded URI that, while marked as benign, suggests a redirection mechanism. Two other URLs were extracted, one of which is hosted on a potentially compromised website, indicating a likely path for delivering a second-stage payload or redirecting to a phishing page.
