T1204.002 Malicious Link
T1566.002 Spearphishing Link
The PDF contains a critical heuristic firing for a malicious redirector link, pointing to 'ttraff.cc'. Additionally, it exhibits a PDF link farm heuristic, with numerous links to Shopify-hosted PDFs, suggesting a tactic to distribute content or mask malicious activity. The document body, though heavily obfuscated, contains text related to 'ctet answer key 2020 paper 2 pdf', aligning with the lure of providing a document. The presence of a 'download button' heuristic further supports the idea of a deceptive download lure.
