Malware Insights
The PDF document exhibits a link farm pattern, with numerous embedded URLs pointing to external resources. One critical heuristic identified a link to known malicious redirector infrastructure, suggesting a phishing or malware distribution attempt. The document body, though partially corrupted, contains text related to a 'farm animal baby matching worksheet' and the authoring tool 'wkhtmltopdf', which is often used to generate malicious PDFs. The primary attack pattern involves leveraging these links to lure users to potentially harmful sites.
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.
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://ttraff.com/wb?keyword=farm%20animal%20baby%20matching%20worksheet
