MITRE ATT&CK

T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF file contains multiple embedded URLs, one of which is a direct link to a suspicious domain ('garglob.ru') that is likely used to deliver a malicious payload. The ClamAV detection and ML classifier strongly indicate malicious intent, consistent with a phishing or trojan distribution scheme. No scripts were extracted, but the presence of numerous external links suggests a downloader or dropper functionality.
