MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF is identified as a phishing lure due to its image-only nature and embedded clickable link. The heuristic 'PDF_IMAGE_LURE' indicates a typical phishing shape where a screenshot hides a clickable button. The embedded URL, https://trafffe.ru/aws?utm_term=mbbs+full+form+in+tamil, is the primary indicator of malicious intent, likely serving as a redirect to a phishing or malware distribution site.
