MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains a screenshot of a document, typical of a phishing lure, designed to trick users into clicking an embedded link. The heuristic 'PDF_IMAGE_LURE' confirms this. The embedded URL, 'https://trafftec.ru/aws?utm_term=acknowledgement+sample+for+ojt+pdf', is the primary indicator of compromise, likely leading to a malicious site. ClamAV also detected this file as 'Pdf.Phishing.Trojan-d2568dad23a94d95-d2568dad23a94d95-10044375-0'.
