I better appreciate the importance of the authenticated encryption with this attack! The data of 0.25 billion users could quite easily be decrypted by whoever had access to MEGA’s systems (including governments and MEGA). It also shows the importance of open source code. I suspect there are far more vulnerabilities and backdoors in closed source proprietary software.
