Malware Insights
The PDF file contains a heuristic firing for a malicious redirector link, pointing to 'https://ttraff.ru/pify?keyword=aqa+a+level+biology+specification+pdf'. Additionally, it exhibits characteristics of a PDF link farm, with numerous embedded links, many of which point to Shopify domains hosting PDF files. The document body, though heavily obfuscated, contains text related to 'Aqa a level biology specification pdf' and the wkhtmltopdf tool, suggesting a lure to disguise the malicious intent. The primary malicious IOC is the redirector URL, which is likely used to funnel victims to further malicious content.
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.
-
