T1566.002 Spearphishing Attachment
T1059.001 PowerShell
T1204.002 Malicious Link
The PDF contains a malicious redirector link pointing to 'ttraff.com', which is flagged as malicious. The document body and embedded links suggest a lure to download a 'free biology textbook', but the primary link leads to a known malicious redirector. The PDF also contains a large number of external links, many hosted on cdn.shopify.com, indicating a link farm for SEO manipulation. No scripts were extracted, but the presence of malicious redirectors and the SEO link farm pattern strongly suggest a phishing or malware distribution attempt.

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=grade+10+biology+textbook+pdf+free
