Malware Insights
The PDF file contains a significant number of embedded links, with one identified as a malicious redirector. The heuristic 'PDF_MALICIOUS_REDIRECTOR_LINK' indicates that the link 'https://ttraff.ru/pify?keyword=pdf+book+app+android' leads to known malicious infrastructure. The 'PDF_SEO_LINK_FARM' heuristic further supports this, noting a mass of external PDF links, many hosted on cdn.shopify.com, suggesting an attempt to manipulate search results or distribute malicious content through a large number of seemingly benign links. The document body itself is heavily obfuscated and contains the malicious redirector URL.
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.
