Malware Insights
The PDF contains a critical heuristic firing for a malicious redirector link, specifically `https://ttraff.cc/pify?keyword=acls+algorithms+2015+pdf`. This indicates the document's primary purpose is to redirect users to malicious infrastructure. Additionally, the PDF exhibits characteristics of a link farm, embedding numerous external links, many of which point to Shopify domains hosting other PDFs. The document body, though heavily obfuscated, contains the malicious URL and several benign-looking PDF links, reinforcing the lure. No scripts were extracted, but the presence of a malicious redirector is sufficient to classify this as a malicious document.
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.cc/pify?keyword=acls+algorithms+2015+pdf
