MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document was identified as malicious due to the presence of a large number of embedded links, a technique commonly used for SEO poisoning and redirecting users to malicious sites. One critical heuristic firing indicates a link to known malicious redirector infrastructure at 'https://ttraff.ru/pify?keyword=neither+nor+either+or+worksheet+pdf'. The document body contains garbled text and the wkhtmltopdf application name, suggesting it was programmatically generated to host these links.
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.
-
