T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF was flagged by multiple critical heuristics indicating malicious redirector links and a link farm for SEO manipulation. The primary malicious URL identified is ttraff.com, which is known to host redirectors. While the document body contains text related to a 'series circuit worksheet', this appears to be a lure to disguise the malicious intent of the embedded links. No scripts were extracted from this sample.

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=series%20circuit%20worksheet%2014.1
