On April 7, 2014, The Heartbleed Bug—a serious vulnerability in encryption technology used by most Web servers to secure communications over the Internet was announced. The good news is that the Martus servers (where all data is stored and backed up) are not affected by Heartbleed. The Martus Desktop client, too, was not affected by the Heartbleed bug. However, Android 4.1.1 is vulnerable. If you use Mobile Martus, we recommend you update Android, then delete and recreate your Martus Mobile account, so that a new private key is generated. If you are unable to update Android 4.1.1 we strongly suggest that you do not use Mobile Martus.
