Peer DSTJ is dead, long live peer Y924

Peer DSTJ is dead, long live peer Y924

After some issues with our infrastructure we needed to replace our bootstrapping peer. To avoid problems when connecting to GNUnet the operator of a peer needs to update its node by removing the peer ID DSTJBRRKZ8TBW3FGK6B0M5QXWT9WYNZ45H5MCV4HY7ST64Q8T9F0 from the system. Here are two strategies to find copies of the respective file:

GNUnet 0.11.5

GNUnet 0.11.5 released

We are pleased to announce the release of GNUnet 0.11.5.
This is a bugfix release for 0.11.4, mostly fixing a few minor bugs and improving performance, in particular for identity management with a large number of egos. In the wake of this release, we also launched the REST API documentation . In terms of usability, users should be aware that there are still a large number of known open issues in particular with respect to ease of use, but also some critical privacy...

GNUnet Hacker Meeting 2019 at La Décentrale, Switzerland

The members of the GNUnet community met again in the wonderful souroundings of St. Imier to hack on GNUnet. New people joined our sessions until late at night. From bug squashing to digging our own dog food, from workshops to theoretical discussions of new services and usecases. And of course, pizza was in the game.

How to Create a Malware Detection System With Machine Learning

In this post we’ll talk about two topics I love and that have been central elements of my (private) research for the last ~7 years: machine learning and malware detection.

Having a rather empirical and definitely non-academic education, I know the struggle of a passionate developer who wants to approach machine learning and is trying to make sense of formal definitions, linear algebra and whatnot. Therefore, I’ll try to keep this as practical as possible in order to allow even the less formally-educated reader to understand and possibly start having fun with neural networks.

Moreover, most of the resources out there...

GNUnet 0.11.4

GNUnet 0.11.4 released

We are pleased to announce the release of GNUnet 0.11.4.
This is a bugfix release for 0.11.3, mostly fixing a few build issues. In terms of usability, users should be aware that there are still a large number of known open issues in particular with respect to ease of use, but also some critical privacy issues especially for mobile users. Also, the nascent network is tiny (about 200 peers) and thus unlikely to provide good anonymity or extensive amounts of interesting information. As a result, the 0.11.4 release is...

GNUnet 0.11.0 released

We are pleased to announce the release of GNUnet 0.11.0.
This is a major release after about five years of development. In terms of usability, users should be aware that there are still a large number of known open issues in particular with respect to ease of use, but also some critical privacy issues especially for mobile users. Also, the nascent network is tiny (about 200 peers) and thus unlikely to provide good anonymity or extensive amounts of interesting information. As a result, the 0.11.0 release is still...

Pwning WPA/WPA2 Networks With Bettercap and the PMKID Client-Less Attack

In this post, I’ll talk about the new WiFi related features that have been recently implemented into bettercap, starting from how the EAPOL 4-way handshake capturing has been automated, to a whole new type of attack that will allow us to recover WPA PSK passwords of an AP without clients.

We’ll start with the assumption that your WiFi card supports monitor mode and packet injection (I use an AWUS1900 with this driver), that you have a working hashcat (v4.2.0 or higher is required) installation (ideally with GPU support enabled) for cracking and that you know how to use it properly either...
