Noroboto: Lying fonts and mitigation in Rust

The article discusses a novel 'lexploit' called Noroboto, which involves creating malicious fonts that misrepresent Unicode characters in legal documents. This vulnerability could be exploited to manipulate document content while appearing legitimate, potentially creating legal advantages. The author explores mitigation strategies using Rust programming language to address this security concern in legal tech stacks.

Background

Modern legal tech stacks rely on complex combinations of open-source and proprietary software for document processing, creating potential vulnerabilities in text rendering and interpretation. The Unicode specification's complexity and the existence of private use areas provide opportunities for exploitation.
