Statement from Directtrust Regarding the EFAIL Vulnerability
Statement from DirectTrust regarding the EFAIL Vulnerability Summary EFAIL is a set of attacks used to exploit vulnerabilities in email clients that decrypt and display PGP and S/MIME encrypted messages by coercing them into sending the decrypted text of the emails to an attacker. Properly implemented, Direct is NOT vulnerable. However, we recommend that if you are exchanging with anyone outside of the DirectTrust Network, you will want to understand at a reasonable depth how their implementation protects against EFAIL. How does EFAIL work? EFAIL consists of two different attack scenarios that create “backchannels” to send the decrypted text to an attacker. Both require an attacker to first obtain the encrypted message. 1. The attacker “wraps” the encrypted body with carefully crafted markup that can result in an email client decrypting the message and sending the decrypted body to the attacker. 2. The attacker manipulates the encrypted body of the message using well known S/MIME weaknesses that produce a message that can send the decrypted body to the attacker once rendered in the email client. Although the attacks are different, the end result is the same: a vulnerable email client sends the decrypted text to the attacker. How is this relevant to Direct? Direct uses S/MIME to encrypt messages, so in theory every Direct message could be vulnerable to this attack. However, Direct, when implemented correctly, is NOT vulnerable. The vulnerability is only applicable if decryption and rendering of the message are done in certain email clients like Thunderbird, iOS, Apple Mail, and some versions of Outlook. -

[Hal-00744922, V1] Improving Content Availability in the I2P Anonymous
Improving Content Availability in the I2P Anonymous File-Sharing Environment Juan Pablo Timpanaro, Isabelle Chrisment*, Olivier Festor INRIA Nancy-Grand Est, France *LORIA - ESIAL, Universit´ede Lorraine Email: fjuanpablo.timpanaro, [email protected] Email: [email protected] Abstract. Anonymous communication has gained more and more inter- est from Internet users as privacy and anonymity problems have emerged. Dedicated anonymous networks such as Freenet and I2P allow anony- mous file-sharing among users. However, one major problem with anony- mous file-sharing networks is that the available content is highly reduced, mostly with outdated files, and non-anonymous networks, such as the BitTorrent network, are still the major source of content: we show that in a 30-days period, 21648 new torrents were introduced in the BitTor- rent community, whilst only 236 were introduced in the anonymous I2P network, for four different categories of content. Therefore, how can a user of these anonymous networks access this varied and non-anonymous content without compromising its anonymity? In this paper, we improve content availability in an anonymous environment by proposing the first internetwork model allowing anonymous users to access and share content in large public communities while remaining anonymous. We show that our approach can efficiently interconnect I2P users and public BitTorrent swarms without affecting their anonymity nor their performance. Our model is fully implemented and freely usable. 1 Introduction Peer-to-peer file-sharing has always been one of the major sources of the Internet hal-00744922, version 1 - 24 Oct 2012 traffic, since its early beginnings in 2000. It has been moving from semi-central approaches (eDonkey2000, for example), to semi-decentralized approaches (Kazaa, for instance) to fully decentralized file-sharing architectures (like the KAD net- work). -

From Wikipedia: Secure Shell (SSH) is a cryptographic network protocol for secure data communication, remote command-line login, remote command execution, and other secure network services between two networked computers that connects, via a secure channel over an insecure network, a server and a client (running SSH server and SSH client programs, respectively). i.e., ssh gives you a secure command line interface on remote machines… Topics • Where SSH applies directly to dealing with these two areas of security: - Confidentiality - Keeping our data safe from prying eyes • Authentication and Authorization - Is this person who they claim to be? - With keys alternative method to passwords Where to get SSH • First see if SSH is installed on your system and what version. Easiest way is: $ ssh ±V • Commonly used SSH in Linux and FreeBSD is OpenSSH. You can find the home page here: http://www.openssh.org/ • You can install OpenSSH via packages on Linux and FreeBSD.
