Malware Insights
The PDF contains a critical heuristic firing for a malicious redirector link, pointing to 'https://ttraff.com/pify?keyword=mathematics+dictionary+download+pdf'. This indicates a social engineering attempt to trick users into clicking the link under the guise of downloading a dictionary. The document also exhibits a PDF link farm, with numerous links hosted on cdn.shopify.com, suggesting an attempt to manipulate search engine results or distribute content widely. No scripts were extracted, and the document body is heavily obfuscated, but the presence of the malicious redirector is sufficient to classify the attack pattern.
Heuristics 3
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
