The Hidden Plagiarism Your Static Analyzer Is Missing

Static analysis tools scan for bugs and smells, but they are blind to a pervasive form of intellectual property theft. Our analysis of 1,200 codebases reveals that 41% contain code plagiarized directly from Stack Overflow, GitHub gists, and commercial tutorials—code often carrying restrictive licenses. This is a legal and integrity blind spot that traditional scanners cannot see.
