T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF was flagged by multiple heuristics, including a machine learning classifier and ClamAV, indicating malicious intent. The presence of an embedded URI pointing to 'resalured.ru' strongly suggests a phishing or credential harvesting attempt. While no scripts were explicitly extracted, the PDF structure and heuristic firings are consistent with a malicious document designed to trick users into visiting a malicious URL.
