T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a heuristic firing for a malicious redirector link, pointing to 'ttraff.cc'. The document body, though heavily obfuscated, contains the same URL and text related to a calculus textbook solution manual, indicating a social engineering lure. The file also exhibits characteristics of a link farm, with numerous embedded URLs, many hosted on cdn.shopify.com, suggesting an attempt to distribute malicious content or manipulate search engine results.
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=calculus+early+transcendentals+11th+edition+solution+manual+pdf
