MITRE ATT&CK

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

The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'https://ttraff.com/wix?keyword=persona+5+shadow+fukurai'. Additionally, it exhibits characteristics of a PDF link farm, with numerous links to external PDFs, suggesting a broader distribution or redirection strategy. The 'SE_PASSWORD_ARCHIVE_LURE' heuristic indicates the document may be part of a multi-stage attack, where the user is instructed to open a password-protected archive, likely containing the actual payload.

Heuristics 4

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.
Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE

Document gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
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.
