This PDF file is identified as malicious by ClamAV and an ML classifier. It employs a common phishing tactic by presenting a full-page screenshot as a lure, with a hidden clickable action. The embedded URL, https://jacksth.ru/aws?utm_term=how+do+i+renew+my+license+during+covid+in+pa, is likely the destination for this malicious action, potentially leading to credential harvesting or further malware deployment.
