The PDF contains a large number of embedded links, many of which point to Shopify domains hosting other PDFs, a technique often used for SEO poisoning or to obscure malicious destinations. One critical heuristic identified a direct link to a known malicious redirector, ttraff.cc, which is likely used to funnel victims to further malicious content. The presence of a 'LOLBin Run Command' heuristic suggests that the PDF may also contain instructions or embedded scripts designed to execute commands on the user's system, potentially leveraging tools like PowerShell.
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.
-
Visible LOLBin command execution instruction high SE_LOLBIN_RUN_COMMANDDocument contains instructions or visible command text involving Windows script/execution tools such as PowerShell, mshta, cmd, rundll32, or regsvr32
-
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.cc/pify?keyword=number+line+to+20+pdf
