Magecart Attacks Evade Detection by Hiding in EXIF Data of Favicons

Magecart payloads can evade detection by hiding within the EXIF data of dynamically loaded third-party favicons, as the malicious code does not reside in the repository itself. Static analysis tools like Claude Code Security fail to identify such threats because they operate at the boundary between code scanning and client-side runtime execution. The attack vector exploits the technical limitation of repository scanners, which cannot analyze code injected post-deployment. No specific dates, CVE IDs, or affected vendors were mentioned in the provided excerpt. The impact involves undetected client-side skimming attacks that bypass traditional security measures.
