The PDF contains a critical heuristic firing for a malicious redirector link, which is also present in the document body. This link is disguised as a download for 'utorrent 64 bit windows 8', indicating a social engineering lure. The PDF also exhibits characteristics of a link farm, with numerous external links, many of which point to benign Shopify domains, but the primary malicious redirector is the key indicator. No scripts were extracted from this sample.
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.
-

-
