Malware Insights
The PDF file contains embedded links, one of which, 'https://ttraff.ru/pify?keyword=consolidation+settlement+calculation+spreadsheet', is identified as a malicious redirector. The document body, though heavily obfuscated, contains references to 'Consolidation settlement calculation spreadsheet' and also includes the malicious URL, suggesting a lure to trick users into clicking the link. The presence of a 'PDF_SEO_LINK_FARM' heuristic further indicates a pattern of hosting numerous links, likely for SEO manipulation or to distribute malicious content. The file is generated by wkhtmltopdf, a tool often abused for creating malicious PDFs.
Heuristics 4
-
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.
-

-
