TL;DR: It is argued that Mirai may represent a sea change in the evolutionary development of botnets--the simplicity through which devices were infected and its precipitous growth, and that novice malicious techniques can compromise enough low-end devices to threaten even some of the best-defended targets.

TL;DR: This work introduces a novel technique for passively detecting HTTPS interception based on handshake characteristics, and assesses the prevalence and impact of HTTPS interception by applying heuristics to nearly eight billion connection handshakes.

TL;DR: In this paper, a server establishes a secure session with a client device where a private key used in the handshake when establishing the secure session is stored in a different server, and the server transmits the encrypted premaster secret to another server for decryption.

TL;DR: In this article, an authentication challenge system for secondary authentication for an account associated with an online store is described, which includes a question generation engine, which can derive a series of questions based upon activity associated with a user account of online store; a network interface can transport the series of one or more questions derived by the question generator to authenticate the user to the online store, and a confidence engine can determine a required confidence level for a successful authentication.

TL;DR: This work provides a solution to prevent users from being exposed to a disproportionate amount of internet challenges such as CAPTCHAs, and detail a 1-RTT cryptographic protocol that allows users to receive a significant amount of anonymous tokens for each challenge solution that they provide.
