Malware Insights
The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'ttraff.com'. Additionally, it exhibits characteristics of a PDF link farm, embedding numerous external links, with the primary one being 'https://cdn.shopify.com/s/files/1/0433/0097/8853/files/84215774092.pdf'. The document body, though heavily obfuscated, contains text referencing 'Casti guidebook to asme b31. 3 pdf' and the 'wkhtmltopdf' tool, suggesting a lure to a fake document. The presence of multiple external PDF links indicates an attempt to distribute content or redirect users to potentially malicious sites.
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.
