The Glassworm attack technique has resurfaced, using invisible Unicode characters to create malicious packages that appear legitimate in GitHub, npm, and VSCode. This sophisticated attack bypasses traditional detection methods by exploiting visual similarity in code repositories. The technique poses significant supply chain security risks as attackers can hide malicious code within seemingly normal-looking files.
Background
Unicode-based attacks exploit character encoding ambiguities to create files that appear legitimate but contain hidden malicious content. These attacks have evolved to target software repositories and development tools where visual inspection is common.
