The PDF file contains a large number of embedded links, with one identified as a malicious redirector. The document body, though heavily obfuscated, contains references to URLs that are likely part of a link farm designed to distribute malicious content. The primary malicious URL identified is https://ttraff.ru/pify?keyword=mysql+blob+pdf+php, which is flagged as a malicious redirector. The presence of numerous links, including those hosted on cdn.shopify.com, suggests a broad distribution attempt.
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=mysql+blob+pdf+php
