Internet Explorer Exploit Steals Data From Windows Users-- Even If They Never Use Internet Explorer
by Peter Reutemann 14 Apr '19

14 Apr '19

'Security researcher John Page has revealed a new zero-day exploit that allows remote attackers to exfiltrate Local files using Internet Explorer. "The craziest part: Windows users don't ever even have to open the now-obsolete web browser for malicious actors to use the exploit," reports Mashable. "It just needs to exist on their computer..." [H]ackers are taking advantage of a vulnerability using .MHT files, which is the file format used by Internet Explorer for its web archives. Current web browsers do not use the .MHT format, so when a PC user attempts to access this file Windows opens IE by default. To initiate the exploit, a user simply needs to open an attachment received by email, messenger, or other file transfer service... Most worrisome, according to Page, is that Microsoft told him that it would just "consider" a fix in a future update. The security researcher says he contacted Microsoft in March before now going public with the issue. As ZDNet points out, while Internet Explorer usage makes up less than 10 percent of the web browser market, it doesn't particularly matter in this case as the exploit just requires a user to have the browser on their PC.' -- source: https://it.slashdot.org/story/19/04/14/2232252 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/

Does Wi-Fi Security Really Matter?
by Lawrence D'Oliveiro 11 Apr '19

11 Apr '19

Seems the Wi-Fi Alliance is having yet another crack at coming up with a really secure protocol, this time to be called WPA3 <http://www.theregister.co.uk/2018/01/09/wi_fi_wpa3/>. Does anybody care? Remember that on the Internet, security is implemented between the endpoints, the protocols are designed not to care that everything in-between might be pawed through by eavesdroppers, or even active attackers trying to inject fake data.

Dragonblood Vulnerabilities Disclosed in Wi-Fi WPA3 Standard
by Peter Reutemann 11 Apr '19

11 Apr '19

'Two security researchers disclosed details this week about a group of vulnerabilities collectively referred to as Dragonblood that impact the Wi-Fi Alliance's recently launched WPA3 Wi-Fi security and authentication standard. From a report: If ever exploited, the vulnerabilities would allow an attacker within the range of a victim's network to recover the Wi-Fi password and infiltrate the target's network. In total, five vulnerabilities are part of the Dragonblood ensemble -- a denial of service attack, two downgrade attacks, and two side-channel information leaks. While the denial of service attack is somewhat unimportant as it only leads to crashing WPA3-compatible access points, the other four are the ones that can be used to recover user passwords. Both the two downgrade attacks and two side-channel leaks exploit design flaws in the WPA3 standard's Dragonfly key exchange -- the mechanism through which clients authenticate on a WPA3 router or access point. In a downgrade attack, Wi-Fi WPA3-capable networks can be coerced in using an older and more insecure password exchange systems, which can allow attackers to retrieve the network passwords using older flaws.' -- source: https://mobile.slashdot.org/story/19/04/11/1431219 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/

Gmail Becomes First Major Email Provider To Support MTA-STS and TLS Reporting
by Peter Reutemann 11 Apr '19

11 Apr '19

'Google announced this week that Gmail has become the first major email provider to support two new security standards, namely MTA-STS and TLS Reporting. From a report: Both are extensions to the Simple Mail Transfer Protocol (SMTP), the protocol through which all emails are sent today. The purpose of MTA-STS and TLS Reporting is to help email providers establish cryptographically secure connections between each other, with the main goal of twarthing SMTP man-in-the-middle attacks. SMTP man-in-the-middle attacks are a major problem for today's email landscape, where rogue email server operators can intercept, read, and modify the contents of people's emails. The two new standards will prevent this by allowing legitimate email providers to create a secure channel for exchanging emails.' -- source: https://tech.slashdot.org/story/19/04/11/1822228 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 Workers Are Listening To What You Tell Alexa
by Peter Reutemann 11 Apr '19

11 Apr '19

'Amazon reportedly employs thousands of people around the world to help improve its Alexa digital assistant. "The team listens to voice recordings captured in Echo owners' homes and offices," reports Bloomberg. "The recordings are transcribed, annotated and then fed back into the software as part of an effort to eliminate gaps in Alexa's understanding of human speech and help it better respond to commands." From the report: The team comprises a mix of contractors and full-time Amazon employees who work in outposts from Boston to Costa Rica, India and Romania, according to the people, who signed nondisclosure agreements barring them from speaking publicly about the program. They work nine hours a day, with each reviewer parsing as many as 1,000 audio clips per shift, according to two workers based at Amazon's Bucharest office, which takes up the top three floors of the Globalworth building in the Romanian capital's up-and-coming Pipera district. The modern facility stands out amid the crumbling infrastructure and bears no exterior sign advertising Amazon's presence. The work is mostly mundane. One worker in Boston said he mined accumulated voice data for specific utterances such as "Taylor Swift" and annotated them to indicate the searcher meant the musical artist. Occasionally the listeners pick up things Echo owners likely would rather stay private: a woman singing badly off key in the shower, say, or a child screaming for help. The teams use internal chat rooms to share files when they need help parsing a muddled word -- or come across an amusing recording. Sometimes they hear recordings they find upsetting, or possibly criminal. Two of the workers said they picked up what they believe was a sexual assault. When something like that happens, they may share the experience in the internal chat room as a way of relieving stress. Amazon says it has procedures in place for workers to follow when they hear something distressing, but two Romania-based employees said that, after requesting guidance for such cases, they were told it wasn't Amazon's job to interfere. [...] Amazon, in its marketing and privacy policy materials, doesn't explicitly say humans are listening to recordings of some conversations picked up by Alexa. "We use your requests to Alexa to train our speech recognition and natural language understanding systems," the company says in a list of frequently asked questions. In Alexa's privacy settings, the company gives users the option of disabling the use of their voice recordings for the development of new features. A screenshot reviewed by Bloomberg shows that the recordings sent to the Alexa auditors don't provide a user's full name and address but are associated with an account number, as well as the user's first name and the device's serial number. An Amazon spokesperson said in a statement to Bloomberg: "We take the security and privacy of our customers' personal information seriously. We only annotate an extremely small sample of Alexa voice recordings in order [to] improve the customer experience. For example, this information helps us train our speech recognition and natural language understanding systems, so Alexa can better understand your requests, and ensure the service works well for everyone." They added: "We have strict technical and operational safeguards, and have a zero tolerance policy for the abuse of our system. Employees do not have direct access to information that can identify the person or account as part of this workflow. All information is treated with high confidentiality and we use multi-factor authentication to restrict access, service encryption and audits of our control environment to protect it."' -- source: https://yro.slashdot.org/story/19/04/10/2340251 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/

You Can Now Use Your Android Phone as a 2FA Security Key for Google Accounts
by Peter Reutemann 10 Apr '19

10 Apr '19

'Google said today it will now enable Android users to use their smartphones as a Fast Identity Online (FIDO) security key (for two-step authentication) for their Google accounts, thereby addressing one of the biggest challenges that has slowed the adoption of this security measure: convenience. A report adds: You can thus use your Android phone to protect your personal Google account, and your G Suite, Cloud Identity, and Google Cloud Platform work accounts. (Android tablets aren't supported -- Google specifically limited the functionality since users are more likely to have phones with them.) This means Android phones can move from two-step verification (2SV) to two-factor authentication (2FA). 2SV is a method of confirming a user's identity using something they know (password) and a second thing they know (a code sent via text message). 2FA is a method of confirming a user's identity by using a combination of two different factors: something they know (password), something they have (security key), or something they are (fingerprint). The feature is coming only to Android devices versions 7 and up.' -- source: https://tech.slashdot.org/story/19/04/10/1621253 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/

Google Chrome Wants To Block Some HTTP File Downloads

'Google wants to block some file downloads carried out via HTTP on websites that use HTTPS. The plan is to block EXE, DMG, CRX, ZIP, GZIP, BZIP, TAR, RAR, and 7Z file downloads when the download is initiated via HTTP but the website URL shows HTTPS. Google said it's currently not thinking of blocking all downloads started from HTTP sites, since the browser already warns users about a site's poor security via the "Not Secure" indicator in the URL bar. The idea is to block insecure downloads on sites that appear to be secure (loaded via HTTPS) but where the downloads take place via plain ol' HTTP.' -- source: https://tech.slashdot.org/story/19/04/10/1758206 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/

Mysterious safety-tampering malware infects a second critical infrastructure site
by Peter Reutemann 10 Apr '19

10 Apr '19

'Sixteen months ago, researchers reported an unsettling escalation in hacks targeting power plants, gas refineries, and other types of critical infrastructure. Attackers who may have been working on behalf of a nation caused an operational outage at a critical-infrastructure site after deliberately targeting a system that prevented health- and life-threatening accidents. Game-changing attack on critical infrastructure site causes outage There had been compromises of critical infrastructure sites before. What was unprecedented in this attack—and of considerable concern to some researchers and critical infrastructure operators—was the use of an advanced piece of malware that targeted the unidentified site’s safety processes. Such safety instrumented systems (SIS) are a combination of hardware and software that many critical infrastructure sites use to prevent unsafe conditions from arising. When gas fuel pressures or reactor temperatures rise to potentially unsafe thresholds, for instance, a SIS will automatically close valves or initiate cooling processes to prevent health- or life-threatening accidents. Russia was likely behind dangerous critical infrastructure attack, report says By focusing on the site’s SIS, the malware carried the threat of physical destruction that depending on the site and the type of accident had the potential to be serious if not catastrophic. The malware was alternately named Triton and Trisis, because it targeted the Triconex product line made by Schneider Electric. It’s development was ultimately linked to a Russian government-backed research institute.' -- source: https://arstechnica.com/information-technology/2019/04/mysterious-safety-ta… 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/

Windows XP Dies Final Death As Embedded POSReady 2009 Reaches End of Life
by Peter Reutemann 10 Apr '19

10 Apr '19

'Extended support for Windows Embedded POSReady 2009 -- the last supported version of Windows based on Windows XP -- ended on April 9, 2019, marking the final end of the Windows NT 5.1 product line after 17 years, 7 months, and 16 days. Counting this edition, Windows XP is the longest-lived version of Windows ever -- a record which is unlikely to be beaten. Despite the nominal end of support for Windows XP five years ago, the existence of POSReady 2009 allowed users to receive security updates on Windows XP Home and Professional SP3 through the use of a registry hack. Microsoft dissuaded users from doing this, stating that they "do not fully protect Windows XP customers," though no attempt was apparently made to prevent users from using this hack. With POSReady reaching the end of support, the flow of these security updates will likewise come to an end.' -- source: https://tech.slashdot.org/story/19/04/10/0017208 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/

Several Major Browsers to Prevent Disabling of Click-Tracking 'Hyperlink Auditing'
by Peter Reutemann 08 Apr '19

08 Apr '19

'A HTML standard called hyperlink auditing that allows sites to track link clicks is enabled by default on Safari, Chrome, Opera, and Microsoft Edge, but will soon have no way to disable it. As it is considered a privacy risk, browsers previously allowed you to disable this feature. Now they are going in the opposite direction. Hyperlink auditing is an HTML standard that allows the creation of special links that ping back to a specified URL when they are clicked on. These pings are done in the form of a POST request to the specified web page that can then examine the request headers to see what page the link was clicked on. The article concludes that "Firefox and Brave win the award" for people who want this click-tracking capability disabled -- since "only Brave and Firefox currently disable it by default, and do not appear to have any plans on enabling it in the future."' -- source: https://news.slashdot.org/story/19/04/07/2338244 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/

Why Aren't People Abandoning Windows For Linux?
by Peter Reutemann 08 Apr '19

08 Apr '19

'This weekend SlashGear published "Reasons to Abandon Windows For Linux," making their case to "Windows users who are curious about the state of Linux for mainstream computing." It tries to enumerate specific reasons why Linux might be the better choice, arguing among other things that: * Updates on Linux are fast and "rarely call for a restart" -- and are also more complete. "Updates are typically downloaded through a 'Software Updater' application that not only checks for operating system patches, but also includes updates for the programs that you've installed from the repository." * Windows "tries to serve a variety of markets...cramming in a scattered array of features" -- and along those lines, that Microsoft "has gradually implemented monetization schemes and methods for extracting user data." And yet you're still paying for that operating system, while Linux is less bloated and "free forever." * "Because less people use Linux, the platform is less targeted by malware and tends to be more secure than Windows" The article also touches on a few other points (including battery life), and predicts that problems with Windows are "bound to get worse over time and will only present more of a case for making the switch to Linux." Long-time Slashdot reader shanen shared the article, along with some new thoughts on why people really stay with Windows: I think the main "excuse" is the perception of reliability, which is really laughable if you've actually read the EULA. Microsoft certainly doesn't have to help anyone at all. I would argue that Windows support is neither a bug nor a feature, but just a marketing ploy. Their original submission suggests that maybe Linux needs to buttress the perception of its reliability with a better financial model -- possibly through a new kind of crowd funding which could also be extended to all open source software, or even to journalism).' -- source: https://linux.slashdot.org/story/19/04/07/2111218 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/

Ongoing DNS hijackings target unpatched consumer routers

'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.

'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/
