What percentage of websites 'leak' their source code, logins, passwords, and keys?

The article discusses a significant security flaw affecting some of the most visited websites. Research by Truffle Security revealed that 4,500 of the top one million websites leaked source code secrets and other sensitive data. The authors emphasize that poor practices in information security can lead to serious breaches. Letters, numbers, and sometimes even API keys and authentication data were found in public repositories, becoming increasingly common. This not only poses a risk to website owners but also to users, as it can lead to data theft. At the core of the issue lies a lack of security education and the need for proper code audits that both companies and developers should undergo.
