T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a mass link farm, with a primary link pointing to a known malicious redirector. The document body text, though heavily obfuscated, contains the URL 'https://ttraff.ru/pify?keyword=errores+gramaticales+pdf', suggesting a lure related to PDF grammar errors. The presence of numerous Shopify-hosted PDF links indicates an attempt to obscure the malicious redirector and potentially leverage benign-looking domains for distribution. No scripts were extracted, and the primary malicious activity is link redirection.
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.ru/pify?keyword=errores+gramaticales+pdf
