MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains numerous embedded links, identified by the PDF_SEO_LINK_FARM heuristic, pointing to various external resources. One critical heuristic, PDF_MALICIOUS_REDIRECTOR_LINK, specifically flags a link to 'ttraff.ru', indicating malicious redirector infrastructure. The document body, though heavily obfuscated, appears to be related to the 'Rc5 algorithm in cryptography pdf' keyword, suggesting a lure to attract users interested in cryptography topics. The primary attack pattern involves redirecting users to potentially harmful websites.
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=rc5+algorithm+in+cryptography+pdf
