Researchers Uncover Privacy Risks from Meta and Yandex Code on Millions of Websites

Researchers have discovered that the code embedded by Meta and "Yandex" on millions of websites can deanonymize users by exploiting legitimate protocols. Browsers like Chrome discreetly send unique identifiers to native applications on Android devices. This method uses legitimate protocols to transmit sensitive information, thereby compromising user privacy. The impacts include the disclosure of unique identifiers, which can be used to track and identify users.
