MITRE ATT&CK

T1566.002 Spearphishing Attachment T1059.001 PowerShell T1204.002 Malicious Link

The PDF file contains a heuristic firing for PDF_MALICIOUS_REDIRECTOR_LINK, indicating a link to a known malicious redirector. The document body, though heavily obfuscated, contains text related to 'emulator games database apk' and a URL that matches the redirector. The PDF also contains a PDF_SEO_LINK_FARM heuristic, suggesting it's part of a larger link farm, with one of the linked PDFs being https://cdn.shopify.com/s/files/1/0432/4088/2340/files/biziporazusofifolije.pdf. The primary malicious URL is https://ttraff.me/wix?keyword=emulator+games+database+apk.

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.
URL https://ttraff.me/wix?keyword=emulator+games+database+apk
