T1204.001 Malicious Link
T1059.001 PowerShell
The PDF file contains a large number of embedded links, identified as a 'PDF SEO Link Farm'. One of these links, 'https://ttraff.ru/pify?keyword=adenosine+mechanism+of+action+pdf', is flagged as a malicious redirector. The document body, though heavily obfuscated, contains metadata suggesting it was generated by wkhtmltopdf, a tool often used to create PDFs from web content. The combination of a link farm and a malicious redirector indicates an attempt to drive traffic to harmful sites, likely for phishing or malware distribution.
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.
