Malware Insights
The PDF file contains embedded links that are designed to appear as legitimate educational content, specifically 'arithmetic sequence practice workshe'. However, static analysis reveals that one of these links, 'https://ttraff.com/wix?keyword=arithmetic+sequence+practice+workshe', points to a known malicious redirector. The PDF also contains a large number of other links, many of which point to benign content, suggesting a link farm used to obscure the malicious redirector. The file's metadata indicates it was generated by wkhtmltopdf, a tool often used to create PDFs from web content, which can be leveraged for malicious purposes.
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.
