MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file contains a large number of embedded links, many pointing to external PDF files, which is characteristic of a link farm designed for SEO manipulation or to host malicious content. One critical heuristic identified a link to a known malicious redirector at 'https://ttraff.ru/pify?keyword=chuy%25E1%25BB%2583n+file+pdf+sang+jpg'. The document body, though heavily obfuscated, contains this URL and other URLs hosted on potentially suspicious domains. The primary attack pattern involves luring users through these links, likely to a malicious site.
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=chuy%25E1%25BB%2583n+file+pdf+sang+jpg
