MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment
T1204.001 Malicious Link
T1059.001 Command and Scripting Interpreter: PowerShell
The PDF contains a critical heuristic firing for a malicious redirector link, pointing to 'https://ttraff.link/pify?keyword=yandex+mp3+d%25C3%25B6n%25C3%25BC%25C5%259Ft%25C3%25BCr%25C3%25BCc%25C3%25BC'. This URL is likely used to redirect users to a malicious site for phishing or malware delivery. The document also contains a large number of embedded URLs, many hosted on Shopify, which is characteristic of SEO poisoning or link farm techniques to obscure the final malicious destination.

Heuristics 4
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF 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_FARMSmall 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.
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
-
Embedded URL info EMBEDDED_URLOne 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.URL https://ttraff.link/pify?keyword=yandex+mp3+d%25C3%25B6n%25C3%25BC%25C5%259Ft%25C3%25BCr%25C3%25BCc%25C3%25BC
