MITRE ATT&CK

T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains multiple embedded links, with a critical heuristic firing for a malicious redirector. The primary malicious URL identified is https://ttraff.ru/pify?keyword=video+games+lana+del+rey+sheet+music+pdf, which is designed to redirect users to further malicious content. Another heuristic indicates a PDF link farm, with https://cdn.shopify.com/s/files/1/0436/4979/4213/files/bejiwevepido.pdf being the first identified link in this farm. The document body contains obfuscated text and the malicious URL.

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.
