Is Bob Sending Mixed Signals?
Is Bob Sending Mixed Signals? Michael Schliep Ian Kariniemi Nicholas Hopper University of Minnesota University of Minnesota University of Minnesota [email protected] [email protected] [email protected] ABSTRACT Demand for end-to-end secure messaging has been growing rapidly and companies have responded by releasing applications that imple- ment end-to-end secure messaging protocols. Signal and protocols based on Signal dominate the secure messaging applications. In this work we analyze conversational security properties provided by the Signal Android application against a variety of real world ad- versaries. We identify vulnerabilities that allow the Signal server to learn the contents of attachments, undetectably re-order and drop messages, and add and drop participants from group conversations. We then perform proof-of-concept attacks against the application to demonstrate the practicality of these vulnerabilities, and suggest mitigations that can detect our attacks. The main conclusion of our work is that we need to consider more than confidentiality and integrity of messages when designing future protocols. We also stress that protocols must protect against compromised servers and at a minimum implement a trust but verify model. 1 INTRODUCTION (a) Alice’s view of the conversa-(b) Bob’s view of the conversa- Recently many software developers and companies have been inte- tion. tion. grating end-to-end encrypted messaging protocols into their chat applications.

Obstacles to the Adoption of Secure Communication Tools
Obstacles to the Adoption of Secure Communication Tools Ruba Abu-Salma M. Angela Sasse Joseph Bonneau University College London, UK University College London, UK Stanford University & EFF, USA Anastasia Danilova Alena Naiakshina Matthew Smith University of Bonn, Germany University of Bonn, Germany University of Bonn, Germany Abstract—The computer security community has advocated Recent mobile phone-based secure communication tools widespread adoption of secure communication tools to counter have often been designed to hide security from the user com- mass surveillance. Several popular personal communication tools pletely (albeit at some security cost [1]). WhatsApp famously (e.g., WhatsApp, iMessage) have adopted end-to-end encryption, and many new tools (e.g., Signal, Telegram) have been launched deployed E2E encryption to approximately a billion users with security as a key selling point. However it remains unclear through a code update to its application for messages, voice if users understand what protection these tools offer, and if they calls and video communications [18], with only negligible value that protection. In this study, we interviewed 60 partici- changes to the user experience. Some other communication pants about their experience with different communication tools tools (e.g., Signal, Threema) have launched with security and their perceptions of the tools’ security properties. We found that the adoption of secure communication tools is hindered by as an explicit selling point, but they also hide nearly all fragmented user bases and incompatible tools. Furthermore, the cryptographic details. vast majority of participants did not understand the essential There are key differences in the security model of dif- concept of end-to-end encryption, limiting their motivation to ferent E2E-encrypted tools, in addition to a large gap in adopt secure tools. -
Untraceable Links: Technology Tricks Used by Crooks to Cover Their Tracks
UNTRACEABLE LINKS: TECHNOLOGY TRICKS USED BY CROOKS TO COVER THEIR TRACKS New mobile apps, underground networks, and crypto-phones are appearing daily. More sophisticated technologies such as mesh networks allow mobile devices to use public Wi-Fi to communicate from one device to another without ever using the cellular network or the Internet. Anonymous and encrypted email services are under development to evade government surveillance. Learn how these new technology capabilities are making anonymous communication easier for fraudsters and helping them cover their tracks. You will learn how to: Define mesh networks. Explain the way underground networks can provide untraceable email. Identify encrypted email services and how they work.
