MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of external links, many of which are related to 'FIFA 22', suggesting a lure to download malicious content. One of the primary URLs, http://xtraserp.com/hypothalamus/aftershocks/ZG93bmxvYWR8Rk05TmpOeE1YeDhNVFkxTnpBek5qSXlNM3g4TWpVM05IeDhLRTBwSUhKbFlXUXRZbXh2WnlCYlJtRnpkQ0JIUlU1ZA/borrowings/bringer/chargeability.zubov/jakks.RmlmYSAyMgRml, is likely the malicious payload delivery point. The PDF SEO Link Farm heuristic indicates a deliberate attempt to create a network of links for malicious purposes.
