T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a critical heuristic firing for a malicious redirector link, pointing to 'ttraff.com'. Additionally, it exhibits a PDF link farm heuristic, with numerous links to external PDFs, many hosted on Shopify. The document body, though heavily obfuscated, contains text related to 'Bihar tet question paper 2020 download pdf', suggesting a lure for exam-related content. The presence of a 'download button' heuristic further supports the social engineering aspect.
