Malware Insights
The PDF file contains multiple embedded URLs, with one identified as a malicious redirector. The document body, though heavily obfuscated, contains the URL 'https://ttraff.cc/pify?keyword=carcinoma+no+microcitico+de+pulmon+pdf', which is flagged as a malicious redirector. The presence of a large number of external PDF links, many pointing to Shopify domains, suggests an attempt to obscure the true malicious destination or to leverage SEO techniques for distribution. The file was generated using wkhtmltopdf, a tool often used to create PDF documents from web content, which can be abused 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.
