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

The PDF document contains a large number of external links, many of which are SEO-optimized and point to pages offering software cracks. One prominent URL, http://findinform.com/bonhoeffer=stomatologist/crookedly/grayish/deliciouslyyorkshire/pubish.ZG93bmxvYWR8clUxWW5KaU1IeDhNVFkxTmpnNU1qTTFNbng4TWpVM05IeDhLRTBwSUhKbFlXUXRZbXh2WnlCYlJtRnpkQ0JIUlU1ZA?trilogy=TXVzaWMgRXh0cmFjdG9yTXV, appears to be a download lure. The heuristic firings indicate a link farm strategy, suggesting the primary goal is to redirect users to malicious content.
