MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file was identified as malicious due to the presence of numerous embedded links. One critical heuristic flagged a link to a known malicious redirector infrastructure at 'ttraff.com'. Another critical heuristic indicated a PDF link farm, with many links pointing to external PDF files hosted on domains like 'cdn.shopify.com' and others. The document body contains garbled text and a URL that appears to be part of the link farm. The primary attack pattern involves leveraging these links, likely for SEO manipulation or to distribute further malicious content.
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/pify?keyword=an+underground+education+richard+zacks+pdf
