Malware Insights
The PDF contains a large number of embedded links, many of which point to external PDF files hosted on various domains, suggesting a link farm for SEO manipulation or to obscure malicious redirects. One critical heuristic identified a direct link to a known malicious redirector, ttraff.cc, which is further obfuscated by a query parameter related to a 'Viber app free for android' lure. The document body contains garbled text but includes the malicious URL and several benign-looking URLs hosted on Shopify, likely part of the link farm. The primary intent appears to be directing users to malicious infrastructure through a deceptive download lure.
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.
