Ongoing DNS hijackings target unpatched consumer routers
by Peter Reutemann 05 Apr '19

05 Apr '19

'A wave of DNS hijacking attacks that abuse Google's cloud computing service is causing consumer routers to connect to fraudulent and potentially malicious websites and addresses, a security researcher has warned. By now, most people know that Domain Name System servers translate human-friendly domain names into the numeric IP addresses that computers need to find other computers on the Internet. Over the past four months, a blog post published Thursday said, attackers have been using Google cloud service to scan the Internet for routers that are vulnerable to remote exploits. When they find susceptible routers, the attackers then use the Google platform to send malicious code that configures the routers to use malicious DNS servers.' -- source: https://arstechnica.com/information-technology/2019/04/ongoing-dns-hijackin… 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 End of the Desktop?
by Peter Reutemann 04 Apr '19

04 Apr '19

'Steven J. Vaughan-Nichols, writing for ComputerWorld : Of course, at one time, to get any work done with a computer, you first had to learn a lot, about computers, operating systems, commands and more. Eventually, "friendly" became the most important adverb in computing circles, and we've reached the point in user-friendliness that people don't even talk about it anymore. Today, Google has shown with its Chrome OS that most of us can pretty much do anything we need to do on a computer with just a web browser. But Google's path is not Microsoft's path. Instead, it's moving us first to Windows as desktop as a service (DaaS) via Microsoft Managed Desktop (MMD). This bundles Windows 10 Enterprise, Office 365 and Enterprise Mobility + Security and cloud-based system management into Microsoft 365 Enterprise. The next step, Windows Virtual Desktop, enables companies to virtualize Windows 7 and 10, Office 365 ProPlus apps and other third-party applications on Azure-based virtual machines. If all goes well, you'll be able to subscribe to Windows Virtual Desktop this fall. Of course, Virtual Desktop is a play for business users -- for now. I expect Virtual Desktop to be offered to consumers in 2020. By 2025, Windows as an actual desktop operating system will be a niche product. Sound crazy? Uh, you do know that Microsoft already really, really wants you to "rent" Office 365 rather than buy Office 2019, don't you? But what about games, you say? We'll always have Windows for games! Will we? Google, with its Google Stadia gaming cloud service, is betting we're ready to move our games to the cloud as well. It's no pipe dream. Valve has been doing pretty well for years now with its Steam variation on this theme. So where is all this taking us? I see a world where the PC desktop disappears for all but a few. Most of us will be writing our documents, filling out our spreadsheets and doing whatever else we now do on our PCs via cloud-based applications on smart terminals running Chrome OS or Windows Lite. If you want a "real" PC, your choices are going to be Linux or macOS.' -- source: https://tech.slashdot.org/story/19/04/04/1724248 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/

'Following the release of Visual Studio 2019 for Windows and Mac platforms, Microsoft today is releasing a snap version of Visual Studio Code. A report adds: No, the source-code editor is not the Windows-maker's first snap -- it also released one for Skype, for instance. "As of today, Visual Studio Code is available for Linux as a snap, providing seamless auto-updates for its users. Visual Studio Code, a free, lightweight code editor, has redefined editors for building modern web and cloud applications, with built-in support for debugging, task running, and version control for a variety of languages and frameworks," says Canonical. Joao Moreno, Software Development Engineer, Microsoft Visual Studio Code offers the following statement: "The automatic update functionality of snaps is a major benefit. It is clear there is a thriving community around snaps and that it is moving forward at great pace. The backing of Canonical ensures our confidence in its ongoing development and long-term future."' -- source: https://linux.slashdot.org/story/19/04/04/1854252 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/

'SPURV' Project Brings Windowed Android Apps To Desktop Linux
by Peter Reutemann 04 Apr '19

04 Apr '19

'A new "experimental containerized Android environment" from a company called Collabora allows Android apps to run in floating windows alongside native applications on desktop Linux. You can read all the technical details at the source link, but put simply, 'SPURV' creates a virtual Android device on your Linux computer, much like Bluestacks and other similar tools. There are various components of SPURV that allow the Android environment to play audio, connect to networks, and display hardware-accelerated graphics through the underlying Linux system. The most interesting part is 'SPURV HWComposer,' which renders Android applications in windows, alongside the windows from native Linux applications. This is what sets SPURV apart from (most) other methods of running Android on a computer. For this to work, the Linux desktop has to be using the Wayland display server (some Linux-based OSes use X11). Pre-built binaries for SPURV are not currently available -- you have to build it yourself from the source code. Still, it's an interesting proof-of-concept, and hopefully someone turns it into a full-featured product.

Serious Apache server bug gives root to baddies in shared host environments
by Peter Reutemann 04 Apr '19

04 Apr '19

'The Apache HTTP Server, the Internet’s most widely used Web server, just fixed a serious vulnerability that makes it possible for untrusted users or software to gain unfettered control of the machine the software runs on. CVE-2019-0211, as the vulnerability is indexed, is a local privilege escalation, meaning it allows a person or software that already has limited access to the Web server to elevate privileges to root. From there, the attacker could do just about anything. The vulnerability makes it possible for unprivileged scripts to overwrite sensitive parts of a server’s memory, Charles Fol, the independent researcher who discovered the bug, wrote in a blog post. A malicious script could exploit the vulnerability to gain root. The vulnerability poses the most risk inside Web-hosting facilities that offer shared instances, in which a single physical machine serves content for more than one website. Typically, such servers prevent an administrator of one site from accessing other sites or from accessing sensitive settings of the machine itself.' -- source: https://arstechnica.com/information-technology/2019/04/serious-apache-serve… 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/

Millions of Facebook Records Found on Amazon Cloud Servers
by Peter Reutemann 03 Apr '19

03 Apr '19

'Researchers at UpGuard, a cybersecurity firm, found troves of Facebook user information hiding in plain sight, inadvertently posted publicly on Amazon.com's cloud computing servers. From a report: The discovery shows that a year after the Cambridge Analytica scandal exposed how unsecure and widely disseminated Facebook users' information is online, companies that control that information at every step still haven't done enough to seal up private data, Bloomberg News reports. In one instance, Mexico City-based media company Cultura Colectiva openly stored 540 million records on Facebook users, including identification numbers, comments, reactions and account names. That database was closed on Wednesday after Bloomberg alerted Facebook to the problem and Facebook contacted Amazon. Facebook shares pared their gains after the Bloomberg News report. UpGuard adds: The data sets vary in when they were last updated, the data points present, and the number of unique individuals in each. What ties them together is that they both contain data about Facebook users, describing their interests, relationships, and interactions, that were available to third party developers. As Facebook faces scrutiny over its data stewardship practices, they have made efforts to reduce third party access. But as these exposures show, the data genie cannot be put back in the bottle. Data about Facebook users has been spread far beyond the bounds of what Facebook can control today. Combine that plenitude of personal data with storage technologies that are often misconfigured for public access, and the result is a long tail of data about Facebook users that continues to leak' -- source: https://yro.slashdot.org/story/19/04/03/182215 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/

Linus Torvalds on Social Media: 'It's a Disease. It Seems To Encourage Bad Behavior.'
by Peter Reutemann 03 Apr '19

03 Apr '19

'From a wide-ranging interview of Linus Torvalds with Linux Journal on the magazine's 25th anniversary: Linux Journal: If you had to fix one thing about the networked world, what would it be? Linus: Nothing technical. But, I absolutely detest modern "social media" -- Twitter, Facebook, Instagram. It's a disease. It seems to encourage bad behavior. I think part of it is something that email shares too, and that I've said before: "On the internet, nobody can hear you being subtle". When you're not talking to somebody face to face, and you miss all the normal social cues, it's easy to miss humor and sarcasm, but it's also very easy to overlook the reaction of the recipient, so you get things like flame wars, etc., that might not happen as easily with face-to-face interaction. But email still works. You still have to put in the effort to write it, and there's generally some actual content (technical or otherwise). The whole "liking" and "sharing" model is just garbage. There is no effort and no quality control. In fact, it's all geared to the reverse of quality control, with lowest common denominator targets, and click-bait, and things designed to generate an emotional response, often one of moral outrage. Add in anonymity, and it's just disgusting. When you don't even put your real name on your garbage (or the garbage you share or like), it really doesn't help. I'm actually one of those people who thinks that anonymity is overrated. Some people confuse privacy and anonymity and think they go hand in hand, and that protecting privacy means that you need to protect anonymity. I think that's wrong. Anonymity is important if you're a whistle-blower, but if you cannot prove your identity, your crazy rant on some social-media platform shouldn't be visible, and you shouldn't be able to share it or like it. Linux Journal: Is there any advice you'd like to give to young programmers/computer science students? Linus: I'm actually the worst person to ask. I knew I was interested in math and computers since an early age, and I was largely self-taught until university. And everything I did was fairly self-driven. So I don't understand the problems people face when they say "what should I do?" It's not where I came from at all.' -- source: https://tech.slashdot.org/story/19/04/03/1829244 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/

How (Not) To Damage A Flash Storage Device
by Lawrence D'Oliveiro 02 Apr '19

02 Apr '19

Came across this article <http://wiki.laptop.org/go/How_to_Damage_a_FLASH_Storage_Device> on the OLPC wiki about some of the things to beware of when reformatting a flash device (USB stick or SD card -- what about SSDs?). Basically, if there is a mismatch between the blocking of data at the filesystem level and the device page size, then you could be increasing the number of hardware-level writes by a factor of 2 or more. This leads to a corresponding reduction in the life of the device.

Mozilla Will Run Two Experiments This Month With Firefox To Explore Ways To Fight Push Notification Permission Spam
by Peter Reutemann 02 Apr '19

02 Apr '19

'Mozilla said this week that it intends to run two experiments over the course of this month to determine the most adequate way of dealing with push notification spam, a growing problem that is slowly deteriorating the web experience for everyone. From a report: The experiments will run in Firefox Nightly (v68) and Firefox Beta (v67). The Firefox Nightly experiment will run from April 1 to April 29. During this time, Mozilla said Firefox Nightly would only allow websites to show a push notification permission only after the user has clicked or pressed a key while on a website. All attempts to show a push notification permission request before a click or key press will be blocked by default. [...] In the last two weeks of the experiment, Firefox will show an icon in the URL bar, but with no visible popup on the page. Users can click this icon and accept any push notification permission requests if they wish so.' -- source: https://news.slashdot.org/story/19/04/02/1941232 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/
