MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF file contains heuristics indicating an external URI and is flagged as malicious by ML and ClamAV. The embedded URL, 'https://jottigo.ru/strik?utm_term=washington+dc+airport+transportation+to+hotels', is likely used to redirect the user to a phishing or malware distribution site. Although no scripts were explicitly extracted, the nature of the PDF and the malicious URL suggest an attempt to trick the user into visiting a harmful site, likely as part of a phishing campaign.
