T1566.001 Spearphishing Attachment

The PDF file is identified as malicious by ClamAV and an ML classifier, exhibiting characteristics of a phishing lure. The 'PDF_IMAGE_LURE' heuristic indicates it's an image-only document with an action trigger, likely a disguised clickable link. The embedded URL 'https://fokemale.ru/award?keyword=antioxidant+activity+of+turmeric+pdf' is the primary indicator of malicious intent, suggesting a phishing or malware distribution attempt. No scripts were extracted from this sample.
