Malware Insights
The PDF file contains a large number of embedded links, many of which point to domains associated with link farms and redirectors, such as ttraff.com. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK indicates that at least one of these links directs to known malicious infrastructure. The PDF_SEO_LINK_FARM heuristic further confirms the malicious intent by identifying a large collection of external PDF links, likely intended to manipulate search engine rankings or distribute malware. No scripts were extracted from this sample, and the document body is heavily obfuscated, but the presence of numerous links to potentially malicious sites strongly suggests a phishing or redirection attack.
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.com/wb?keyword=quadratic%20standard%20to%20vertex%20form%20worksheet
