MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file is identified as malicious by ClamAV and an ML classifier. It exhibits characteristics of a phishing lure, being image-only and small in size, with a clickable action pointing to an external URL. The embedded URL, 'https://traffnew.ru/aws?utm_term=adding+subtracting+mixed+numbers+worksheet+pdf', is the primary indicator of compromise, likely serving as a gateway to malicious content.
