  • A [Windows] virus has thrown Philadelphia’s court system into chaos

     

    Since May 21st, a virus has shut down Philadelphia’s online court system, bringing network access to a standstill. The problems started unexpectedly: suddenly, no one could seem to access the system to file documents. “It wasn’t working,” says Rachel Gallegos, a senior staff attorney with the civil legal aid organization Community Legal Services. “I thought it was my computer.”

  • Linux Command-Line Editors Vulnerable to High-Severity Bug

     

    Vim and Neovim have both released patches for the bug (CVE-2019-12735) that the National Institute of Standards and Technology warns, “allows remote attackers to execute arbitrary OS commands via the :source! command in a modeline.”
     

    “Beyond patching, it’s recommended to disable modelines in the vimrc (set nomodeline), to use the securemodelinesplugin, or to disable modelineexpr (since patch 8.1.1366, Vim-only) to disallow expressions in modelines,” the researcher said.

  • The bits and bytes of PKI

    In two previous articles—An introduction to cryptography and public key infrastructure and How do private keys work in PKI and cryptography?—I discussed cryptography and public key infrastructure (PKI) in a general way. I talked about how digital bundles called certificates store public keys and identifying information. These bundles contain a lot of complexity, and it's useful to have a basic understanding of the format for when you need to look under the hood.

28 facts about Linux for its 28th birthday

Nearly three decades ago, Linus Torvalds sent the email announcing Linux, a free operating system that was "just a hobby" and not "big and professional like GNU." It's fair to say that Linux has had an enormous influence on technology and the world in general in the 28 years since Torvalds announced it. Most people already know the "origin story" of Linux, though. Here's 28 things about Linux (the kernel and larger ecosystem) you may not already know. 1 - Linux isn't very useful alone, so folks took to creating Linux distributions to bundle user software with it, make it usable and easier to install. The first Linux distribution was Softlanding Linux System (SLS), first released in 1992 and using the .96p4 Linux kernel. You could buy it on 5.25" or 3.5" floppies, or CD-ROM if you were high-tech. If you wanted a GUI, you needed at least 8MB of RAM. 2 - SLS didn't last, but it influenced Slackware Linux, which was first released in 1993 and is still under development today. Slackware is the oldest surviving Linux distribution and celebrated its 26th birthday on July 17th this year. 3 - Linux has the largest install base of any general purpose operating system. It powers everything from all 500 of the Top 500 Supercomputers to Android phones, Chomebooks, and all manner of embedded devices and things like the Kindle eBook readers and smart televisions.
