  • [Update: Arriving] Chromebook Pixel 2015, 8 more Chrome OS devices to get Linux apps support soon

    The ability to run Linux apps has opened the door for Chromebooks to become more than just a glorified web browser, but an actual workstation. Many older devices, however, were unable to get Linux apps support, due to not having the necessary hardware. Other Chromebooks were held back because their underlying Linux kernel for Chrome OS was much older and thus didn’t have everything necessary to integrate Linux apps properly.

    A handful of devices from 2015, including that year’s Chromebook Pixel, were stuck in an awkward place, being too outdated for Linux apps to be easily possible and being too new to be ignored completely. Last August, the Chromium team said that the fate of these devices was still “undecided,” which is why they’re not explicitly mentioned in Chromium documentation.

    In the intervening months, Google has been hard at work on a project called “kernelnext,” which seems poised to update the Linux kernel of certain devices, starting with the 2015 Chromebook Pixel (aka Samus), from version 3.14 to 4.14. There are actually eight other Chrome OS devices built on the same Broadwell generation Intel processors found in the 2015 Chromebook Pixel, all of which are also being tested with “kernelnext.”

Security Leftovers

  • Security Researchers Find Several Bugs in Nest Security Cameras

    Researchers Lilith Wyatt and Claudio Bozzato of Cisco Talos discovered the vulnerabilities and disclosed them publicly on August 19. The two found eight vulnerabilities that are based in the Nest implementation of the Weave protocol. The Weave protocol is designed specifically for communications among Internet of Things or IoT devices.

  • Better SSH Authentication with Keybase

    With an SSH CA model, you start by generating a single SSH key called the CA key. The public key is placed on each server and the server is configured to trust any key signed by the CA key. This CA key is then used to sign user keys with an expiration window. This means that signed user keys can only be used for a finite, preferably short, period of time before a new signature is needed. This transforms the key management problem into a user management problem: How do we ensure that only certain people are able to provision new signed SSH keys?

  • Texas ransomware attacks deliver wake-up call to cities [iophk: Windows TCO]

    The Texas Department of Information Resources has confirmed that 22 Texas entities, mostly local governments, have been hit by the ransomware attacks that took place late last week. The department pointed to a “single threat actor” as being responsible for the attacks, which did not impact any statewide systems.

    On Security Now, Steve Gibson talks about a huge ransomware attack. 23 cities in Texas were hit with a well-coordinated ransomware attack last Friday, August 16th.

  • CVE-2019-10071: Timing Attack in HMAC Verification in Apache Tapestry

    Apache Tapestry uses HMACs to verify the integrity of objects stored on the client side. This was added to address the Java deserialization vulnerability disclosed in CVE-2014-1972. In the fix for the previous vulnerability, the HMACs were compared by string comparison, which is known to be vulnerable to timing attacks.

GNOME Feeds is a Simple RSS Reader for Linux Desktops

Feedreader, Liferea, and Thunderbird are three of the most popular desktop RSS readers for Linux, but now there’s a new option on the scene. GNOME Feeds app is simple, no-frills desktop RSS reader for Linux systems. It doesn’t integrate or sync with a cloud-based service, like Feedly or Inoreader, but you can import a list of feeds via an .opml file. “Power” users of RSS feeds will likely find that GNOME Feeds a little too limited for their needs. But the lean feature set is, arguably, what will make this app appeal to more casual users. Read more

GNU Radio Launches 3.8.0.0, First Minor-Version Release In Six Years

The GNU Radio maintainers have announced the release of GNU Radio 3.8.0.0, the first minor-version release of the popular LimeSDR-compatible software defined radio (SDR) development toolkit in over six years. “It’s the first minor release version since more than six years, not without pride this community stands to face the brightest future SDR on general purpose hardware ever had,” the project’s maintainers announced this week. “What has not changed is the fact that GNU Radio is centred around a very simple truth: Let the developers hack on DSP. Software interfaces are for humans, not the other way around. And so, compared to the later 3.7 releases, nothing has fundamentally modified the way one develops signal processing systems with GNU Radio: You write blocks, and you combine blocks to be part of a larger signal processing flow graph.” Read more

IBM/Red Hat Leftovers

  • Accelerating the journey to open hybrid cloud with Red Hat Modernization and Migration Solutions

    The integration of technology into all areas of a business (the "digital transformation" we hear so much about) is fundamentally changing how organizations operate as well as how they deliver value to customers. An example is Lockheed Martin, who opted to undergo an eight-week agile transformation labs residency to implement an open source architecture onboard the F-22 and simultaneously disentangle its web of embedded systems. But such transformation can also create new challenges, from additional competitive pressures to increased customer expectations. To help overcome these challenges, Red Hat is introducing a family of solutions to help optimize infrastructure, modernize applications and accelerate innovation while supporting customers in their journey to the open hybrid cloud. Red Hat Modernization and Migration Solutions are designed to help customers realize the benefits of open technologies and adopt containers, Kubernetes and hybrid cloud-ready platforms. The family of solutions offers a path for customers from restrictive, proprietary environments to more flexible and (often) less costly open source alternatives, in an iterative approach.

  • Let’s talk about Privacy by Design

    Privacy by Design or Privacy by Default (PbD) is not a new concept. However PbD received renewed attention when the GDPR added PbD as a legal requirement. PbD refers to the process of building in technical, organizational and security measures at the beginning stage of product development and throughout the product lifecycle. [...] One PbD tool we use to build in privacy to our development process is our Privacy Impact Assessment, also known as a PIA. The PIA is a process which assists developers at the early stages in identifying and mitigating privacy risks associated with the collection and use of personal data. The PIA tool begins with a self assessment that asks a lot of questions about the planned project or product. This initiates a process of review by individuals trained in privacy and security. The process is collaborative and creates an on-going dialogue about privacy with respect to the product, system or application at hand.
