  • Security at the Edge: hardware accelerated AI-based cybersecurity with Canonical Ubuntu and the BlueField-2 DPU

    During GTC last fall, NVIDIA announced an increased focus on the enterprise datacenter, including their vision of the datacenter-on-a-chip. The three pillars of this new software-defined datacenter include the data processing unit (DPU) along with the CPU and GPU. The NVIDIA BlueField DPU advances SmartNIC technology, which NVIDIA acquired through their Mellanox acquisition in 2020. Here at Canonical, we are proud of our long partnership with NVIDIA to provide the best experience to developers and customers on Ubuntu. This work has advanced the state of the art with secure NVIDIA GPU drivers and provisions for GPU pass-through. Our engineering teams collaborate deeply to provide the fastest path to the newest features and the latest patches for critical vulnerabilities. For networking, this has meant partnering with Mellanox (now NVIDIA) engineering to provide not just Ubuntu support but also support for hardware offload going back to the oldest ConnectX devices. In fact, Ubuntu was the first Linux distro enabled on the Bluefield cards back in 2019. Increasingly, Ubuntu, which has long been the operating system of choice for cutting-edge machine learning developers, data scientists, containers and Kubernetes is seeing more enterprise adoption across verticals.

  • Print Friendly & PDF: Full compromise

    I looked into the Print Friendly & PDF browser extension while helping someone figure out an issue they were having. The issue turned out unrelated to the extension, but I already noticed something that looked very odd. A quick investigation later I could confirm a massive vulnerability affecting all of its users (close to 1 million of them). Any website could easily gain complete control of the extension.
