Release of OpenSSH 9.6 with vulnerability fixes

Posted on

The release of OpenSSH 9.6 has been published, an open-source implementation of a client and server for working with SSH 2.0 and SFTP protocols. The new version addresses three security issues: a vulnerability in the SSH protocol (CVE-2023-48795, the 'Terrapin' attack) that allows a MitM attack to downgrade the connection to use less secure authentication algorithms and disable protection against attacks through side channels that recreate input via […]

Terrapin — a vulnerability in the SSH protocol that can reduce the security of the connection.

Posted on

A group of researchers from Ruhr University Bochum (Germany) has introduced a new technique for a MitM attack on SSH — Terrapin, which exploits a vulnerability (CVE-2023-48795) in the protocol. An attacker capable of conducting a MitM attack can block the transmission of a message setting protocol extensions during the connection negotiation phase to reduce the security level of the connection. A prototype toolkit for performing the attack has been published on GitHub. In the context of OpenSSH, the vulnerability […]

The Linux kernel 6.8 is set to include the first network driver written in Rust.

Posted on

Changes have been added to the net-next branch, which develops changes for the Linux kernel 6.8, incorporating an initial Rust wrapper over the phylib abstraction layer and using this wrapper for the ax88796b_rust driver, which provides support for the PHY interface of the Asix AX88772A Ethernet controller (100MBit). The driver consists of 135 lines of code and is positioned as a simple working example for creating network drivers in Rust, ready […]

postmarketOS 23.12 is now available, a Linux distribution for smartphones and mobile devices.

Posted on

After 6 months of development, the postmarketOS 23.12 release has been presented, which develops a Linux distribution for smartphones based on the Alpine Linux package base, the standard C library Musl, and the BusyBox utility set. The objective of the project is to provide a Linux distribution for smartphones that is independent of the life cycle of support for official firmware and is not tied to typical solutions from major industry players dictating the direction of development. The builds […]

Release of Radix cross Linux distribution 1.9.300

Posted on

The next version of the Radix cross Linux distribution 1.9.300 is available, built using the proprietary Radix.pro build system, which simplifies the creation of distributions for embedded systems. The distribution builds are available for devices based on ARM/ARM64, MIPS, and x86/x86_64 architectures. The boot images, prepared according to the instructions in the Platform Download section, contain a local package repository and therefore do not require an Internet connection for system installation. […]

SSH3 has been introduced, a variant of the SSH protocol that uses HTTP/3

Posted on

The first official release of the experimental implementation of the server and client for the SSH3 protocol is available. This is designed as an extension over the HTTP/3 protocol, utilizing QUIC (based on UDP) and TLS 1.3 to establish a secure communication channel and employ HTTP mechanisms for user authentication. The project is being developed by François Michel, a PhD student at the Catholic University of Leuven (Belgium), with the participation of Olivier Bonaventure, […]

Hacking MongoDB infrastructure

Posted on

In the infrastructure of the company MongoDB, which develops the eponymous document-oriented DBMS and the cloud service MongoDB Atlas, traces of a breach were found. According to a notification sent to the company's clients, the attackers managed to gain access to some corporate systems, which included, among other things, information about customer accounts and user contact details. Evidence indicates that the attackers accessed the data, […]

Mining cards AMD BC-250 with defective chips from Sony PlayStation 5 have appeared on eBay

Posted on

The AMD BC-250 graphics card was a sort of Frankenstein's monster — it was equipped with defective chips for the Sony PlayStation 5 and was intended for cryptocurrency mining. While mining with graphics cards was profitable, some companies produced such equipment on a large scale using any chips, but now it is more of a museum exhibit, and it has been spotted on eBay, albeit at a high price. […]
