Rendershock: Weaponizing Trust In File Rendering Pipelines
RenderShock is a comprehensive zero-click attack strategy that targets passive file preview, indexing, and automation behaviours in modern operating systems and enterprise environments.
Unlike traditional phishing or malware campaigns requiring a user’s active participation, RenderShock uses standard system behaviours and trusted automation features to perform malicious actions ranging from reconnaissance and data exfiltration to credential theft and remote code execution. By embedding malicious logic in metadata, preview triggers, and document formats, RenderShock capitalizes on system convenience as an unguarded attack vector..:
