Matrix Tchap app suffers security breach


Elliot Alderson (better known as Baptiste Robert) is a security researcher who discovered that Tchap's identification system, an application developed by Matrix, contained a vulnerability that allowed access to any user. In his case, he added the text @elysee.fr at the end of his own email address, so that he could send the validation email to his personal account.

Alderson warned both the French government, which has begun to use it as a secure communication platform internally for its employees, and Matrix, which has already solved the vulnerability.
