Period Tracker Apps Used By Millions Of Women Are Sharing Incredibly Sensitive Data With Facebook
by Peter Reutemann 10 Sep '19

10 Sep '19

'Period tracker apps are sending deeply personal information about women's health and sexual practices to Facebook, new research has found. From a report: UK-based advocacy group Privacy International, sharing its findings exclusively with BuzzFeed News, discovered period-tracking apps including MIA Fem and Maya sent women's use of contraception, the timings of their monthly periods, symptoms like swelling and cramps, and more, directly to Facebook. Women use such apps for a range of purposes, from tracking their period cycles to maximizing their chances of conceiving a child. On the Google Play store, Maya, owned by India-based Plackal Tech, has more than 5 million downloads. Period Tracker MIA Fem: Ovulation Calculator, owned by Cyprus-based Mobapp Development Limited, says it has more than 2 million users around the world. They are also available on the App Store. The data sharing with Facebook happens via Facebook's Software Development Kit (SDK), which helps app developers incorporate particular features and collect user data so Facebook can show them targeted ads, among other functions. When a user puts personal information into an app, that information may also be sent by the SDK to Facebook.' -- source: https://yro.slashdot.org/story/19/09/10/209208 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 Will Soon Encrypt DNS Requests By Default
by Peter Reutemann 10 Sep '19

10 Sep '19

'This month Firefox will make DNS over encrypted HTTPS the default for the U.S., with a gradual roll-out starting in late September, reports Engadget: Your online habits should be that much more private and secure, with fewer chances for DNS hijacking and activity monitoring. Not every request will use HTTPS. Mozilla is relying on a "fallback" method that will revert to your operating system's default DNS if there's either a specific need for them (such as some parental controls and enterprise configurations) or an outright lookup failure. This should respect the choices of users and IT managers who need the feature turned off, Mozilla said. The team is watching out for potential abuses, though, and will "revisit" its approach if attackers use a canary domain to disable the technology. Users will be given the option to opt-out, explains Mozilla's official announcement. "After many experiments, we've demonstrated that we have a reliable service whose performance is good, that we can detect and mitigate key deployment problems, and that most of our users will benefit from the greater protections of encrypted DNS traffic." "We feel confident that enabling DNS-over-HTTPS by default is the right next step."' -- source: https://news.slashdot.org/story/19/09/08/0318237 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 State Of Windows RT Strike 2
by Lawrence D'Oliveiro 10 Sep '19

10 Sep '19

The IFA show currently on in Berlin <https://www.theregister.co.uk/2019/09/10/windows_on_arm_intel/> has a couple of exhibitors showing off devices running Windows-on-ARM. (Or, more accurately, Windows-on-specific-Qualcomm-ARM-chipsets-only.) While they offer good battery life, they are expensive, and have compatibility issues (no emulation for 64-bit Windows x86 executables, only 32-bit ones). And Intel clearly doesn’t like them.

Mozilla Launches VPN as Part of Resurrected Firefox Test Pilot Program
by Peter Reutemann 10 Sep '19

10 Sep '19

'Mozilla is resurrecting its recently expunged Test Pilot program with a renewed focus on privacy-focused tools and products. The Firefox developer today lifted the lid on the first product to emerge from the new Test Pilot, and it appears to be something akin to a virtual private network (VPN) in all but name. From a report: Firefox Private Network, as the new tool is called, is available in beta today for logged-in Firefox desktop users in the U.S. only, and is accessible through a browser extension. By way of a quick recap, Mozilla debuted Firefox Test Pilot a decade ago but then relaunched it back in 2016. Test Pilot went on to attain an average of 100,000 daily users, each looking to test Mozilla's latest developments -- including a price-tracking feature for online shoppers, content recommendations based on browsing activity, and more. Some of these became full-fledged features within Firefox and others did not, but back in January Mozilla announced it was killing its Test Pilot program altogether. This came as something of a surprise given Mozilla's own statements about the success of the program. At the time, Mozilla said it was "evolving" its approach to experimentation and suggested it was looking to ideate more widely across the company. Fast-forward nine months, and Firefox Test Pilot is back for a third time.' -- source: https://yro.slashdot.org/story/19/09/10/1514241 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/

Weakness in Intel chips lets researchers steal encrypted SSH keystrokes
by Peter Reutemann 10 Sep '19

10 Sep '19

'In late 2011, Intel introduced a performance enhancement to its line of server processors that allowed network cards and other peripherals to connect directly to a CPU's last-level cache, rather than following the standard (and significantly longer) path through the server's main memory. By avoiding system memory, Intel's DDIO—short for Data-Direct I/O—increased input/output bandwidth and reduced latency and power consumption. Now, researchers are warning that, in certain scenarios, attackers can abuse DDIO to obtain keystrokes and possibly other types of sensitive data that flow through the memory of vulnerable servers. The most serious form of attack can take place in data centers and cloud environments that have both DDIO and remote direct memory access enabled to allow servers to exchange data. A server leased by a malicious hacker could abuse the vulnerability to attack other customers. To prove their point, the researchers devised an attack that allows a server to steal keystrokes typed into the protected SSH (or secure shell session) established between another server and an application server.' -- source: https://arstechnica.com/information-technology/2019/09/weakness-in-intel-ch… 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/

Thousands of Servers Infected With New Lilocked (Lilu) Ransomware
by Peter Reutemann 09 Sep '19

09 Sep '19

'Thousands of web servers have been infected and had their files encrypted by a new strain of ransomware named Lilocked (or Lilu). Infections have been happening since mid-July, and have intensified in the past two weeks, ZDNet has learned. Based on current evidence, the Lilocked ransomware appears to target Linux-based systems only. The way the Lilocked gang breaches servers and encrypts their content is currently unknown. A thread on a Russian-speaking forum puts forward the theory that crooks might be targeting systems running outdated Exim (email) software. It also mentions that the ransomware managed to get root access to servers by unknown means. Lilocked doesn't encrypt system files, but only a small subset of file extensions, such as HTML, SHTML, JS, CSS, PHP, INI, and various image file formats. This means infected servers continue to run normally. According to French security researcher Benkow, Lilocked has encrypted more than 6,700 servers, many of which have been indexed and cached in Google search results. However, the number of victims is suspected to be much much higher. Not all Linux systems run web servers, and there are many other infected systems that haven't been indexed in Google search results. Why it should scare you: - affects Linux servers - so far the vector of infection / vulnerability is unknown - you can craft a Google search to watch it spread!

Web Scraping Is Legal--For Now
by Lawrence D'Oliveiro 09 Sep '19

09 Sep '19

LinkedIn has been suing a company called hiQ for scraping information from public user profiles, and so far it has lost, twice <https://www.theregister.co.uk/2019/09/09/hiq_wins_linkedin_appeal/>. But of course LinkedIn, being owned by Microsoft, has much deeper legal pockets, and will simply continue a war of attrition until hiQ gives up.

Guidemaster: How to buy a Chromebook, plus our best picks
by Peter Reutemann 09 Sep '19

09 Sep '19

'Chromebooks dominated the affordable laptop scene in 2018. The same wasn't true just a few years ago, when most were unclear what to do with Google's browser-based operating system. But now, after Chromebooks have successfully infiltrated the education market, users both young and old are familiar with Chrome OS. Chrome OS runs exclusively on Chromebooks, the name for the laptops, two-in-ones, and now tablets that run Google's operating system. If you've used the Chrome Web browser before, you know how to use Chrome OS—the browser is the portal to nearly everything you can do on Chrome OS. Google created an operating system that's simple to use, efficient, and low maintenance in the sense that it doesn't take a ton of power to run a Chromebook well. All of those factors, plus the recent introduction of Android apps into the ecosystem, have made Chromebooks popular with younger users, teachers, and anyone who works and plays primarily within the confines of the Chrome Web browser. As people gravitate to Chromebooks, OEMs have been producing more and more of them. There is a plethora of Chromebooks available now, some at dirt cheap prices and others at premium prices, making it hard to know which you should buy. Luckily, Ars has tested some of the most popular Chromebooks, and we can offer some insight as to which ones are worth your money.' -- source: https://arstechnica.com/gadgets/2019/09/guidemaster-how-to-buy-a-chromebook… 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 Bug Started Mistakenly Sending 'Final Update' Notifications
by Peter Reutemann 09 Sep '19

09 Sep '19

'Like it or not, Chromebooks do have something of an expiration date when you purchase them, namely that one day they'll stop receiving updates. Thankfully, that date is typically over five years after the Chromebook's original release. For some, however, Chrome OS has been wrongly indicating this week that their Chromebook has received its "final update" many years too early. Just like the Chrome browser on desktop and Android, Chrome OS has four different update "channels" -- Stable, Beta, Dev, and Canary. Each one of these after Stable trades a level of stability for more rapid updates, with Canary receiving highly unstable updates almost every day. People who are bold enough to put their Chromebook on Dev or Canary have been facing an interesting new issue for the past few days. Upon restarting their device, Chrome OS immediately displays a notification warning that "this is the last automatic software and security update for this Chromebook." Of course, if you're seeing this message this week, there's a decent chance that this is not actually the case. Instead, these final update warnings are caused by a bug in the most recent versions of Chrome OS.

The Feature-rich Vivaldi Browser Arrives on Android
by Peter Reutemann 09 Sep '19

09 Sep '19

'Almost three years after launching its desktop version, cross-platform browser Vivaldi has finally released its mobile app today. From a report: The brainchild of Opera's co-founder Jon von Tetzchner published an Android beta version today that brings swipe gesture for navigation, built-in note-taking functionality, and privacy controls including a no-tracking option. While the browser is in beta, I've been using it for a few days, and I haven't faced any major hiccups. Here are some of the features I enjoyed in the new mobile version: Easy bookmark management, easy navigation, plenty of option for tab management, and dark mode, screen capture, notes, and no-tracking features.' -- source: https://tech.slashdot.org/story/19/09/09/1610214 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/
