T1059.001 PowerShell
The PDF file contains a heuristic firing for a malicious redirector link, pointing to ttraff.ru. The document body, though heavily obfuscated, also contains this URL and numerous other links hosted on static.usrfiles.com, suggesting a link farm or redirection strategy. The primary malicious IOC is the ttraff.ru URL, which likely leads to further malicious content or phishing pages.

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.
