T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a lure for a vocabulary quiz, which is a common social engineering tactic to entice users to click on embedded links. The primary link, 'https://ttraff.cc/wix?keyword=the+great+gatsby+vocabulary+quiz', is identified as a malicious redirector. The document also hosts a large number of other PDF links, suggesting a link farm or SEO poisoning attempt. No scripts were extracted, and the document body was heavily obfuscated, but the presence of the malicious redirector is a strong indicator of malicious intent.
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/wix?keyword=the+great+gatsby+vocabulary+quiz
