Malware Insights
The PDF file contains a large number of embedded links, many of which point to a known malicious redirector. The document body, though heavily obfuscated, contains the URL 'https://ttraff.ru/wb?keyword=dengue%20pdf%20in%20bengali', which is flagged as a malicious redirector. The heuristic 'PDF_MALICIOUS_REDIRECTOR_LINK' confirms this, indicating the document's primary purpose is to redirect users to malicious sites. The heuristic 'PDF_SEO_LINK_FARM' further supports this by identifying a mass of external PDF links, suggesting an attempt to manipulate search engine results or distribute 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.
