T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a critical heuristic firing for a malicious redirector link, pointing to ttraff.cc. The document body, though heavily obfuscated, contains the same URL and appears to be a lure for "Mcse notes server 2016 pdf" with a call-to-action button. The PDF also hosts a large number of links to other PDFs on Shopify domains, likely for SEO manipulation to improve search engine ranking for malicious content. The primary malicious URL is https://ttraff.cc/wb?keyword=mcse%20notes%20server%202016%20pdf.
