Malware Insights
The PDF file contains a heuristic firing for a malicious redirector link, specifically 'https://ttraff.cc/pify?keyword=approval+sheet+meaning'. It also exhibits characteristics of a PDF link farm, embedding a large number of external links, many of which point to potentially malicious or unknown domains. The document body, though heavily obfuscated, contains references to the redirector URL and other PDF links, suggesting an attempt to disguise malicious activity as a document sharing or information retrieval process. The primary attack pattern involves luring the user through these embedded links to a malicious site.
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=approval+sheet+meaning
