MITRE ATT&CK

T1566.001 Spearphishing Attachment

This PDF document is identified as a phishing lure due to its small size and image-only content, typical of a screenshot designed to trick users into clicking an external link. The primary malicious URL, https://baarspo.ru/award?keyword=malaria+treatment+guidelines+2020+pdf, is likely used to deliver a malicious payload or redirect to a phishing page. The presence of numerous other PDF links suggests an attempt to obscure the malicious intent or participate in link farming.
