T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a significant number of embedded links, with a critical heuristic firing indicating a PDF link to known malicious redirector infrastructure. The primary URL identified is 'https://ttraff.ru/wix?keyword=process+control+modeling+design+and+simulation', which is flagged as malicious. Additionally, a large number of external PDF links were found, suggesting a link farm or a method to distribute further malicious content. The document body contains garbled text and the authoring application is wkhtmltopdf, indicating it was likely generated programmatically.
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.
-
