T1204.002 Malicious Link
T1566.002 Spearphishing Attachment
The PDF contains a critical heuristic firing for a malicious redirector link, specifically pointing to 'ttraff.ru'. This URL is associated with a lure for remote support tools like AnyDesk. The document also contains a large number of embedded links, many of which point to PDF files hosted on various domains, suggesting a link farm for SEO poisoning or traffic generation. The presence of a remote-support tool lure in an unsolicited document is a high-risk indicator.
Heuristics 4
-
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.
-
