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

The PDF document contains a large number of external links, many of which point to other PDF files with SEO-optimized titles, suggesting a link farm designed to attract users searching for software cracks. The primary URL, http://evacdir.com/..., appears to be a download endpoint for malicious content. The document body was heavily obfuscated and unreadable, preventing a more detailed analysis of its specific lure.
