However, the messages are encrypted end-to-end and both the encrypted messages and keys in the key pools are authenticated end-to-end. Message securityīy compromising the server, the attacker gains access to encrypted messages as well as public ephemeral key pools. We discuss each type of attack in the sections that follow. Attacks aimed at availability, or the destruction of data.Attacks aimed at information and metadata, or collecting and weaponizing sensitive information about the system or its users.Attacks aimed at message security, or accessing plaintext message content.
It also provides centralized user directory services, permission sets, and profile and setting synchronization.Īttacks attempting to exploit the Wickr server can be generally categorized as follows: The Wickr server plays a key role in message delivery in support of both synchronous and asynchronous communication. To understand what an attacker can do with a Wickr server compromise, we need to understand the role of the server in Wickr architecture and consider the value of the data contained in back end components and databases. It summarizes key elements of Wickr’s security architecture that provide resilience to back-end server compromise and discusses the event in terms of actual attacker capabilities, or real-world impact. This paper examines the issue of security and server compromise more broadly.
As part of our recently released Customer Security Promises, a leading independent security firm validated that message content is not readable on our back-end server components. Third-party experts have continuously vetted our end-to-end encryption and security from the start.
