MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.001 User Execution: Malicious Link T1059.001 PowerShell

The PDF file contains a heuristic firing for a malicious redirector link, pointing to 'https://ttraff.ru/wix?keyword=seriales+eset+smart+security+8'. This URL is presented within the document body, suggesting a lure to trick users into visiting a potentially harmful site. The file also exhibits characteristics of a link farm, with numerous embedded URLs, many hosted on shopify.com, indicating an attempt to broaden reach or obscure the malicious destination. No scripts were extracted from this sample.

Heuristics 3

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.
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.
