MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 User Execution: Malicious Link

The PDF file contains a lure for 'Arcane quest legends offline apk' and embeds a link that redirects to malicious infrastructure. The PDF_MALICIOUS_REDIRECTOR_LINK heuristic confirms the redirection to a known malicious site. Additionally, the PDF_SEO_LINK_FARM heuristic indicates a large number of outbound links, suggesting a spam or phishing campaign. The presence of a download-themed call-to-action further supports a social engineering attack.

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.
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
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.
