Executive Summary

Cybercriminals are increasingly weaponizing SVG (Scalable Vector Graphics) files as delivery vectors for stealthy malware attacks. These vector graphics files appear benign to users as they display legitimate images, but they can be embedded with malicious scripts or code. The technique exploits user trust in visual content, making detection difficult since security filters often whitelist image file formats. Organizations should implement robust file scanning solutions, disable JavaScript execution in SVG rendering applications, and educate users about the risks of opening unexpected file attachments regardless of their apparent file type. Content Security Policies should be configured to restrict inline scripts that could be embedded in SVG files.
