Malware Insights
The PDF file contains a link farm designed to redirect users to malicious infrastructure, specifically identified by the critical heuristic PDF_MALICIOUS_REDIRECTOR_LINK. The primary malicious URL is https://ttraff.ru/pify?keyword=carrier+air+conditioner+brochure+pdf. The document body, though heavily obfuscated, contains references to 'Carrier air conditioner brochure pdf' and the authoring application 'wkhtmltopdf', suggesting a lure to disguise the malicious links. The presence of numerous links to Shopify-hosted PDFs, many of which are benign, indicates an attempt to blend malicious content with seemingly legitimate resources.
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.
