The PDF file contains a link to a known malicious redirector, ttraff.ru, which is likely used to direct users to malicious content. The document body, though heavily obfuscated, contains the same URL and appears to be a lure related to song lyrics. The presence of numerous other benign-looking PDF links suggests a link farm or SEO poisoning attempt to mask the malicious URL.

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.
-
