MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a mass external link farm, with many links pointing to potentially malicious redirectors. The primary heuristic firing indicates a PDF redirector link to 'ttraff.cc', which is known malicious infrastructure. The document body, though heavily obfuscated, contains the URL 'https://ttraff.cc/pify?keyword=cambridge+b2+speaking+exam+pdf', suggesting a lure related to a Cambridge B2 speaking exam. The numerous embedded links, including those hosted on Shopify, are likely part of a link farm designed to obscure the malicious destination.
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=cambridge+b2+speaking+exam+pdf
