MITRE ATT&CK

T1204.001 Malicious Link T1566.002 Spearphishing Attachment

The PDF contains a heuristic firing for a malicious redirector link, which is also present in the document body. The document also exhibits characteristics of a link farm and uses a social engineering lure to prompt the user to install a browser extension or viewer. The primary malicious URL identified is ttraff.cc, which redirects to a page related to 'watch dogs 2 mods pc'.

Heuristics 4

PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

PDF 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_FARM

Small 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.
Browser extension / update installation lure high SE_BROWSER_INSTALL_LURE

Document tells the user to install a browser extension, plugin, viewer, or browser update to view content — a common social-engineering path for credential theft and malware installation
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
