MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The sample is a PDF document that employs social engineering tactics, specifically a 'ClickFix' lure, to prompt the user to execute commands or visit malicious URLs. The document body and embedded URLs suggest a lure related to game cheats or generators, aiming to trick users into downloading further malicious content. The ML classifier also strongly indicated maliciousness.

Heuristics 4

ClickFix social engineering attack high SE_CLICKFIX

Document instructs the user to press Win+R or paste a command into a terminal — consistent with ClickFix attacks that bypass macro restrictions by tricking users into running malicious commands directly
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.
