T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file contains a critical heuristic firing for a malicious redirector link, pointing to 'ttraff.ru'. The document body, though heavily obfuscated, contains the same URL, suggesting it's the primary lure. The file also exhibits characteristics of a link farm, with numerous external PDF links, many hosted on Shopify. The ML classifier strongly indicates maliciousness. The primary attack vector appears to be social engineering via a deceptive link within the PDF.

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.
