T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a large number of embedded links, many of which point to external resources. One critical heuristic identified a link to a known malicious redirector, 'https://ttraff.ru/pify?keyword=mathworksheets4kids+ordering+integers'. Another critical heuristic flagged the PDF as a link farm, with numerous links hosted on cdn.shopify.com. The document body contains text related to 'mathworksheets4kids ordering integers' and includes the malicious redirector URL and a Shopify URL, suggesting a lure to potentially 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.
-
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.ru/pify?keyword=mathworksheets4kids+ordering+integers
