Encrypted emails guarded by common encryption tools are allegedly "susceptible to critical vulnerabilities" that would expose their content to potential hackers. Sebastian Schnizel, a computer science professor from the University of Münster called attention to the 'Efail' issue on Sunday via Twitter. He subsequently urged users of PGP/GPG and S/Mime software to disable it in their email clients.
