T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a heuristic firing for a malicious redirector link pointing to 'https://ttraff.ru/wix?keyword=renaissance+periodization+auto+templ'. It also contains a PDF link farm heuristic, with many links hosted on cdn.shopify.com, one of which is 'https://cdn.shopify.com/s/files/1/0430/7235/6513/files/27309936780.pdf'. The document body contains what appears to be obfuscated text and the malicious URL, suggesting a lure to a malicious site.
Heuristics 4
-
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.
-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
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.ru/wix?keyword=renaissance+periodization+auto+templ
