Security: Google and Tesla

  • Google and Certbot (Letsencrypt)

    It turns out that Google Safebrowsing had listed those two sites. Visit https://listen.gw90.de/ or https://mail.gw90.de/ today (and maybe for some weeks or months in the future) using Google Chrome (or any other browser that uses the Google Safebrowsing database) and it will tell you the site is “Dangerous” and probably refuse to let you in.

    One thing to note is that neither of those sites has any real content, I only set them up in Apache to get SSL certificates that are used for other purposes (like mail transfer as the name suggests). If Google had listed my blog as a “Dangerous” site I wouldn’t be so surprised, WordPress has had more than a few security issues in the past and it’s not implausible that someone could have compromised it and made it serve up hostile content without me noticing. But the two sites in question have a DocumentRoot that is owned by root and was (until a few days ago) entirely empty, now they have a index.html that just says “This site is empty”. It’s theoretically possible that someone could have exploited a RCE bug in Apache to make it serve up content that isn’t in the DocumentRoot, but that seems unlikely (why waste an Apache 0day on one of the less important of my personal sites). It is possible that the virtual machine in question was compromised (a VM on that server has been compromised before [1]) but it seems unlikely that they would host bad things on those web sites if they did.

    Now it could be that some other hostname under that domain had something inappropriate (I haven’t yet investigated all possibilities). But if so Google’s algorithm has a couple of significant problems, firstly if they are blacklisting sites related to one that had an issue then it would probably make more sense to blacklist by IP address (which means including some coker.com.au entries on the same IP). In the case of a compromised server it seems more likely to have multiple bad sites on one IP than multiple bad subdomains on different IPs (given that none of the hostnames in question have changed IP address recently and Google of course knows this). The next issue is that extending blacklisting doesn’t make sense unless there is evidence of hostile intent. I’m pretty sure that Google won’t blacklist all of ibm.com when (not if) a server in that domain gets compromised. I guess they have different policies for sites of different scale.

  • Google Chrome’s New Password Manager: All You Need To Know & How To Use It [Ed: Google wants you to give it all of your passwords. Foolishly forgetting that, according to Snowden's leaks, the US government too gets access to those]

    Google Chrome Password suggestion

    Similar to other Password managers out there, Chrome has added native support for password suggestions. In other words, when you will type in a new password, Chrome browser will automatically generate a password suggestion for you.

    This undoubtedly leaves out the question of using those puppy names and including your first name in your passwords. Now, don’t ask me why they are considered weak passwords.

  • Google slammed for Chrome change that strips out 'www' from domains [iophk: "machines have names for a reason, this breaks the web"

    Google's move to strip out the www in domains typed into the address bar, beginning with version 69 of its Chrome browser, has drawn an enormous amount of criticism from developers who see the move as a bid to cement the company's dominance of the Web.

  • Tesla Launches Bounty Program; Allows Good Faith Hackers To Inspect Firmware
  • Cory Doctorow: Big Tech: We Can Do Better Than Constitutional Monarchies

    Which brings me to the techlash: the post-Brexit, post-Trump, post-Equifax turning point where suddenly a lot of people start to pay attention to the rules we set for technology users, companies, and practitioners.

    I’m genuinely delighted that this moment has arrived. Tech policy is like climate change: every year we fail to fix it is a year that we accumulate more bad tech debt (insecure systems full of sensitive data and attached to machines, sensors and actuators that can harm or kill us). We are in a race between the point of no return, when it’s too late to fix things, and the point of “peak indifference,” when the number of people who care starts to rise of its own accord, thanks to the gaudy disasters detonating all around us.

    But it’s not enough to do something: we have to do something good. And we’re getting it really wrong.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
