T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'ttraff.ru'. This URL is presented within the document body, disguised as a calculus formula PDF. The file also exhibits a PDF link farm heuristic, indicating a large number of outbound links, many of which are to benign Shopify domains, likely for SEO manipulation. The primary malicious IOC is the redirector URL.
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.
