T1204.002 Malicious Link
The PDF contains a heuristic firing for a malicious redirector link pointing to 'https://ttraff.ru/wix?keyword=core+java+interview+questions+for+experience+pdf'. Additionally, the PDF exhibits characteristics of a link farm, with numerous embedded URLs, many hosted on Shopify. The document body, though heavily obfuscated, contains the same malicious URL and appears to be a lure for 'core java interview questions'. The ML classifier strongly flagged this PDF as malicious.
