  • Atom Hackable Text Editor Gets Asynchronous Context Menus, Read-Only TextEditors

    GitHub updated today its open-source and cross-platform Atom hackable text editor app to add asynchronous context menus, read-only TextEditors, and automatic scrolling on unfolding and folding.

    Atom 1.24 is now available for Linux, Windows, and macOS, bringing asynchronous context menus to no longer lock up the even loop on right-click and allow other rendering and processing operations to occur when the context menu is displayed, a new LanguageMode API, automatic scrolling when folding or unfolding, and read-only TextEditors.

    "Packages can apply a read-only attribute to TextEditors to disable input," says Ash Wilson in the release notes. "This is useful when you wish to display code with syntax highlighting and allow copying to the clipboard, but it doesn’t make sense for the user to be able to change it, for example because it’s code in your git history or it isn’t on your local drive."

Security: Japan's Top Cybersecurity Official, SuperCooKey, Information Breach on HealthCare.gov

  • Security News This Week: Japan's Top Cybersecurity Official Has Never Used a Computer
  • SuperCooKey – A SuperCookie Built Into TLS 1.2 and 1.3

    TLS 1.3 has a heavily touted feature called 0-RTT that has been paraded by CloudFlare as a huge speed benefit to users because it allows sessions to be resumed quickly from previous visits. This immediately raised an eyebrow for me because this means that full negotiation is not taking place.

    After more research, I’ve discovered that 0-RTT does skip renegotiation steps that involve generating new keys.

    This means that every time 0-RTT is used, the server knows that you’ve been to the site before, and it knows all associated IPs and sign-in credentials attached to that particular key.

    In October 2018, a breach occurred within the Marketplace system used by agents and brokers. This breach allowed inappropriate access to the personal information of approximately 75,000 people who are listed on Marketplace applications.

The Spectre/Meltdown Performance Impact On Linux 4.20, Decimating Benchmarks With New STIBP Overhead

As outlined yesterday, significant slowdowns with the Linux 4.20 kernel turned out to be due to the addition of the kernel-side bits for STIBP (Single Thread Indirect Branch Predictors) for cross-HyperThread Spectre Variant Two mitigation. This has incurred significant performance penalties with the STIBP support in its current state with Linux 4.20 Git and is enabled by default at least for Intel systems with up-to-date microcode. Here are some follow-up benchmarks looking at the performance hit with the Linux 4.20 development kernel as well as the overall Spectre and Meltdown mitigation impact on this latest version of the Linux kernel. Some users have said AMD also needs STIBP, but at least with Linux 4.20 Git and the AMD systems I have tested with their up-to-date BIOS/microcode, that hasn't appeared to be the case. Most of the AMD STIBP references date back to January when Spectre/Meltdown first came to light. We'll see in the week ahead if there is any comment from AMD but at this time seems to be affecting up-to-date Intel systems with the Linux 4.20 kernel. Read more
