MITRE ATT&CK

T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains a link disguised as a 'Google play music exporter' tool. This link, https://ttraff.cc/wix?keyword=google+play+music+exporter, redirects to malicious infrastructure, indicating a phishing or redirection attempt. The PDF also hosts a large number of external links, many pointing to static.usrfiles.com, suggesting a link farm or SEO manipulation tactic to obscure the malicious redirector. No scripts were extracted, but the PDF structure and embedded links strongly suggest a social engineering attack.

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.
