MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

This PDF document exhibits characteristics of a phishing or scam attempt, specifically a lure for game hacks. It contains numerous external links, many of which are structured as SEO-optimized PDF links, suggesting a link farm. The document explicitly requests recovery secrets or private keys, a high-risk indicator for credential harvesting. The primary URL points to a 'coin-master-hack-download' resource, reinforcing the scam narrative.

Heuristics 5

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.
Recovery secret / private key request critical SE_SECRET_RECOVERY_LURE

Document requests recovery phrases, private keys, backup codes, or saved passwords. Requests for these secrets in a document are high-risk.
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
External URI info PDF_URI

PDF contains an external URL action
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.
