DNS-over-HTTPS Will Eventually Roll Out in All Major Browsers, Despite ISP Opposition
by Peter Reutemann 09 Nov '19

09 Nov '19

' All major browsers -- including Chrome, Firefox, Safari, Opera, Microsoft Edge, Vivaldi, Brave -- have plans to support DNS-over-HTTPS (or DoH), a protocol that encrypts DNS traffic and helps improve a user's privacy on the web. From a report: The DoH protocol has been one of the year's hot topics. It's a protocol that, when deployed inside a browser, it allows the browser to hide DNS requests and responses inside regular-looking HTTPS traffic. Doing this makes a user's DNS traffic invisible to third-party network observers, such as ISPs. But while users love DoH and have deemed it a privacy boon, ISPs, networking operators, and cyber-security vendors hate it. A UK ISP called Mozilla an "internet villain" for its plans to roll out DoH, and a Comcast-backed lobby group has been caught preparing a misleading document about DoH that they were planning to present to US lawmakers in the hopes of preventing DoH's broader rollout. However, this may be a little too late. ZDNet has spent the week reaching out to major web browser providers to gauge their future plans regarding DoH, and all vendors plan to ship it, in one form or another.' -- source: https://it.slashdot.org/story/19/11/08/189243 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox Turns 15
by Peter Reutemann 09 Nov '19

09 Nov '19

'On November 9 2004, a new version of Mozilla's browser called Firefox shipped. It was taking on one of the most daunting monopolies in tech: Microsoft's Internet Explorer, which had more than 90 percent market share. But Firefox was really good, and it became an instant hit, ending Microsoft's dominance of the web. Over at Fast Company, Sean Captain took a look at the browser's original rise, the challenges it faced after Google's Chrome arrived on the scene, and the moves it's currently making to put user privacy first.' -- source: https://news.slashdot.org/story/19/11/08/162243 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

GitLab Director Resigns, Says It's Engaging In 'Retaliatory Behavior'
by Peter Reutemann 09 Nov '19

09 Nov '19

'Candice Ciresi, GitLab's director of risk and global compliance, has resigned after less than six months on the job, apparently saying that the $2.75 billion startup is "engaging in discriminatory and retaliatory behavior." Business Insider reports: Notably, Ciresi resigned in public: GitLab espouses a culture of transparency, whereby all major product and corporate policy decisions are announced and discussed where anybody can see. She posted her resignation in response to one such discussion -- an active debate over a proposed GitLab policy, in which it would ban the hiring of people who live in China or Russia for any role that would require access to customer data. At the time of writing, Ciresi's post announcing her resignation had been reviewed and then "redacted" by GitLab, citing concerns that it would "further inflame this situation." However, Ciresi's comment went out via email to GitLab users who had subscribed to this particular discussion. Per a screenshot posted to Reddit, Ciresi wrote: "As I believe GitLab is engaging in discriminatory and retaliatory behavior, I have tendered my resignation." "We did decide to moderate this post for review, as there have already been credible personal and physical threats against GitLab employees in this issue thread," GitLab says, in part, in place of Ciresi's comment. "While this particular post did not contain a personal threat to anyone, we were concerned it would further inflame this situation." GitLab confirmed Ciresi's departure but didn't comment any further' -- source: https://developers.slashdot.org/story/19/11/08/2216219 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Chrome OS 78 Rolling Out With Picture-In-Picture Support For YouTube, Split Browser/Device Settings, More
by Peter Reutemann 08 Nov '19

08 Nov '19

'The latest version of Chrome OS, version 78, adds separate browser and device settings, click-to-call, and picture-in-picture support for YouTube. It also introduces virtual desktop support for the operating system with a feature called Virtual Desks. 9to5Google reports: Chrome is getting another cross-device sharing feature after "Send this page" widely rolled in September. With "click-to-call," you can right-click on phone number links -- like tel:800-800-8000 -- to have them sent to your Android device. It's quicker than manually entering those digits or transferring via email. Chrome OS 78 will separate browser and device settings. The former is accessible directly at chrome://settings and what opens when clicking "Settings" at the bottom of the Overflow menu in the top-right corner of any browser window. It opens as a tab and provides web-related preferences. Meanwhile, chrome://os-settings opens as its own window, and can be accessed from the quick settings sheet. It provides device options like Wi-Fi, Bluetooth, and Assistant in a white Material Theme UI with an icon in the launcher/app shelf. YouTube for Android now supports picture-in-picture with Chrome OS 78. After starting a video in the mobile client, switching to another window, covering, or minimizing the app will automatically open a PiP in the bottom-right corner. Available controls include switching to audio, play/pause, and skipping to the next track. In the top-left, you can expand the window and a settings gear on the other side allows you to open system settings. Tapping in the center expands and returns you to the YouTube Android app. Chrome OS 78 simplifies the printing experience by automatically listing compatible printers without any prior setup required. There are also a number of Linux on Chrome OS enhancements in this version: - Backups of Linux apps and files can now be saved to local storage, external drive, or Google Drive. That copy can be then restored when setting up a new computer. - Crostini GPU support will be enabled by default for a "crisp, lower-latency experience." - You'll be warned when using a Linux app that does not support virtual keyboard in tablet mode.' -- source: https://linux.slashdot.org/story/19/11/07/2341228 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Amazon Ring Doorbells Exposed Home Wi-Fi Passwords To Hackers
by Peter Reutemann 08 Nov '19

08 Nov '19

'Security researchers have discovered a vulnerability in Ring doorbells that exposed the passwords for the Wi-Fi networks to which they were connected. Bitdefender said the Amazon-owned doorbell was sending owners' Wi-Fi passwords in cleartext as the doorbell joins the local network, allowing nearby hackers to intercept the Wi-Fi password and gain access to the network to launch larger attacks or conduct surveillance. "When first configuring the device, the smartphone app must send the wireless network credentials. This takes place in an unsecure manner, through an unprotected access point," said Bitdefender. "Once this network is up, the app connects to it automatically, queries the device, then sends the credentials to the local network." But all of this is carried out over an unencrypted connection, exposing the Wi-Fi password that is sent over the air. Amazon fixed the vulnerability in all Ring devices in September, but the vulnerability was only disclosed today.' -- source: https://mobile.slashdot.org/story/19/11/07/2125208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft’s Project Silica offers robust thousand-year storage
by Peter Reutemann 08 Nov '19

08 Nov '19

Not strictly Linux or open source related, but I wouldn't mind having a backup that lasts longer than just a few years! 'Ars spoke Tuesday with Dr. Ant Rowstron, a principal researcher at Microsoft Research in Cambridge, UK, about an innovative cold storage project called Silica. Silica aims to replace both tape and optical archival discs as the media of choice for large-scale, (very) long duration cold storage. Microsoft Research is partnering with film giant Warner Bros., which is directly interested in reducing costs and increasing reliability in its own cold storage programs. The medium in question is a block of high-purity glass, which has voxels etched into it with femtosecond lasers. Each voxel stores multiple bits in two properties, retardance and angle, which may in turn be read using microscope imaging and polarized light. Voxels may be written 100 or more layers deep in a 2mm-deep piece of glass, by focusing the laser to the desired depth within the block itself. The speed of both reads and writes to Silica currently leave something to be desired—it took approximately a week to etch Superman's roughly 76GB of data last year, and Rowstron estimates it would take about three days to re-read the data, with advances made since. The technology is still in its infancy, of course, and large decreases in time required for both writing and reading are expected moving forward. Rowstron says he still doesn't expect anyone is likely to try to actually play Superman directly from its Silica record—but that's not what it's intended for.' -- source: https://arstechnica.com/gadgets/2019/11/microsofts-project-silica-offers-ro… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The Original Google Pixel Will Get One Final Update In December
by Peter Reutemann 06 Nov '19

06 Nov '19

'Google has confirmed to The Verge that it will release "one final software update" next month for the original Google Pixel and Pixel XL. From the report: As of yesterday, it looked like the original Pixel was done getting updates, as Google released its November security update for most Pixel phones, but nothing for the Pixel or Pixel XL. Google tells The Verge that the Pixels won't get that November update, but it says December's "encapsulates a variety of updates" from the November and December updates that were issued for other Pixels. It wasn't too surprising to see that Google's original Pixels didn't get yesterday's update. When Google announced the phones in 2016, the company said they would get two years of guaranteed Android version updates and three years of security updates, which is also reflected on Google's support page. That said, Google surprised Pixel owners earlier this year by letting them run Android 10, which is one more year of Android than Google originally promised, and now, they have one final update to look forward to as well.

Android Bug Lets Hackers Plant Malware Via NFC Beaming
by Peter Reutemann 05 Nov '19

05 Nov '19

'Google patched last month an Android bug that can let hackers spread malware to a nearby phone via a little-known Android OS feature called NFC beaming. NFC beaming works via an internal Android OS service known as Android Beam. This service allows an Android device to send data such as images, files, videos, or even apps, to another nearby device using NFC (Near-Field Communication) radio waves, as an alternative to WiFi or Bluetooth. Typically, apps (APK files) sent via NFC beaming are stored on disk and a notification is shown on screen. The notification asks the device owner if he wants to allow the NFC service to install an app from an unknown source. But, in January this year, a security researcher named Y. Shafranovich discovered that apps sent via NFC beaming on Android 8 (Oreo) or later versions would not show this prompt. Instead, the notification would allow the user to install the app with one tap, without any security warning. The CVE-2019-2114 bug resided in the fact that the Android Beam app was also whitelisted, receiving the same level of trust as the official Play Store app. Google said this wasn't meant to happen, as the Android Beam service was never meant as a way to install applications, but merely as a way to transfer data from device to device. The October 2019 Android patches removed the Android Beam service from the OS whitelist of trusted sources. However, many millions of users remain at risk. If users have the NFC service and the Android Beam service enabled, a nearby attacker could plant malware (malicious apps) on their phones. Since most newly-sold devices have the NFC feature enabled by default, you'll have to disable Android Beam and NFC or update your phone to receive the October 2019 security updates if you want to protect yourself from this bug.' -- source: https://it.slashdot.org/story/19/11/04/216228 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Researchers hack Siri, Alexa, and Google Home by shining lasers at them
by Peter Reutemann 05 Nov '19

05 Nov '19

'Siri, Alexa, and Google Assistant are vulnerable to attacks that use lasers to inject inaudible—and sometimes invisible—commands into the devices and surreptitiously cause them to unlock doors, visit websites, and locate, unlock, and start vehicles, researchers report in a research paper published on Monday. Dubbed Light Commands, the attack works against Facebook Portal and a variety of phones. Shining a low-powered laser into these voice-activated systems allows attackers to inject commands of their choice from as far away as 360 feet (110m). Because voice-controlled systems often don’t require users to authenticate themselves, the attack can frequently be carried out without the need of a password or PIN. Even when the systems require authentication for certain actions, it may be feasible to brute force the PIN, since many devices don’t limit the number of guesses a user can make. Among other things, light-based commands can be sent from one building to another and penetrate glass when a vulnerable device is kept near a closed window. The attack exploits a vulnerability in microphones that use micro-electro-mechanical systems, or MEMS. The microscopic MEMS components of these microphones unintentionally respond to light as if it were sound. While the researchers tested only Siri, Alexa, Google Assistant, Facebook Portal, and a small number of tablets and phones, the researchers believe all devices that use MEMS microphones are susceptible to Light Commands attacks.' -- source: https://arstechnica.com/information-technology/2019/11/researchers-hack-sir… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Linus Torvalds: 'I'm Not a Programmer Anymore'
by Peter Reutemann 04 Nov '19

04 Nov '19

'Linus Torvalds, Linux's creator, doesn't make speeches anymore. But, what he does do, and he did again at Open Source Summit Europe in Lyon France is have public conversations with his friend Dirk Hohndel, VMware's Chief Open Source Officer. In this keynote discussion, Torvalds revealed that he doesn't think he's a programmer anymore. So what does the person everyone thinks of as a programmer's programmer do instead? Torvalds explained: "I don't know coding at all anymore. Most of the code I write is in my e-mails. So somebody sends me a patch ... I [reply with] pseudo code. I'm so used to editing patches now I sometimes edit patches and send out the patch without having ever tested it. I literally wrote it in the mail and say, 'I think this is how it should be done,' but this is what I do, I am not a programmer." So, Hohndel asked, "What is your job?" Torvalds replied, "I read and write a lot of email. My job really is, in the end, is to say 'no.' Somebody has to say 'no' to [this patch or that pull request]. And because developers know that if they do something that I'll say 'no' to, they do a better job of writing the code."' -- source: https://linux.slashdot.org/story/19/11/03/2230223 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
