MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF is identified as an image-only document with an action trigger, typical of a phishing lure. It contains an embedded URI pointing to a suspicious domain, which is likely intended to lead the user to a malicious site or download. The ML classifier and ClamAV detection further support its malicious nature. No scripts were extracted, but the overall structure and embedded URL suggest a phishing or malware distribution attempt.
