MITRE ATT&CK

T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF contains a critical heuristic firing for a malicious redirector link, specifically pointing to 'ttraff.ru'. The document body, though heavily obfuscated, contains the same URL and a reference to 'John deere 5520', suggesting a lure. The PDF also exhibits a link farm heuristic, with numerous links pointing to Shopify-hosted PDFs, indicating a potential attempt to distribute further malicious content or engage in SEO manipulation for malicious purposes. 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.
