Alphabet's Cybersecurity Group Touts Its New Open Source Private VPN
by Peter Reutemann 25 Nov '18

25 Nov '18

'Alphabet's cybersecurity division Jigsaw has designed a new open source private VPN aimed at journalists and the people sending them data. "Their work makes them more vulnerable to attack," said Santiago Andrigo, Jigsaw's product manager. "It can get really scary when they're outed and you're passing over information." Unscrupulous VPN providers can steal your identity, peek in on your data, inject their own ads on non-secure pages, or analyze your browsing habits and sell that information to advertisers, says one Jigsaw official. And you can't know for sure whether you can trust them, no matter what they say in the app store. "Journalists should be aware that their online activities might be subject to surveillance either by government agencies, their internet service providers or a hacker with malicious intent," said Laura Tich, technical evangelist for Code for Africa, a resource for African journalists. "As surveillance becomes ubiquitous in today's world, journalists face an increasing challenge in establishing secure communication in the digital space." The new private VPN, dubbed "Outline", is specifically designed to be resistant to censorship — because it's harder to detect as a VPN (and therefore is less likely to be blocked). Outline uses an encrypted socks5 proxy that looks like normal internet traffic. Once the user chooses a server location, Outline spins up a DigitalOcean server on Ubuntu, installs Docker, and imports an image of the actual server. It's been named Outline because in places where internet use may be restricted — it gives you a line out.' -- source: https://yro.slashdot.org/story/18/11/25/0117226 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/

New Gmail Bug Allows Sending Messages Anonymously
by Peter Reutemann 25 Nov '18

25 Nov '18

'Earlier this week software developer Tim Cotten discovered a serious glitch in Gmail. An anonymous reader quotes BleepingComputer: Tampering with the 'From:' header by replacing some text with an <object>, <script> or <img> tag causes the interface to show a blank space instead of the sender's address.... Opening the email does not help, either, as the sender's address continues to remain hidden and shows no info even when hovering on it, an action that typically reveals the details.... Trying to reply to the message is also of no help. Cotten attempted this thinking that Gmail would read the original email headers and determine the destination. "Wrong again! Gmail is at a complete loss at what to do!" Cotten writes in a blog post that details his new finding.... Using the Show Original option, which allows users with more experience to trace an email, the desired detail is still unavailable in the user-friendly view. Looking at the raw info, however, shows the source address buried at the end of the <img> tag Cotten used in his experiment. He didn't even have to spell correctly the data type to trigger the bug. Unfortunately, it is highly unlikely that the average Gmail user will be able to navigate to this area and determine who the apparently anonymous message is coming from. Due to this, for these users the risk of phishing is high. Cotten's bug report "relies on his previous discovery that proved how a malformed 'From:' header allows placing an arbitrary email address in the sender field," the article points out, also noting a third recently-reported Gmail bug that "allows fraudsters to create a 'mailto:' link that populates the destination field in the app with whatever address they want; the latter was reported about 19 months ago to Google and is still present in the Gmail app for Android." "According to the developer, one solution Google could implement to avoid forging the From field is to properly check the email headers and deny communication with an anomalous structure in the sender or recipient fields. Another method proposed by Cotten is Joran Greef's project Ronomon, which can trigger errors when email specifications are not followed." Threatpost reported Tuesday that Google "did not respond to a request for comment."' -- source: https://it.slashdot.org/story/18/11/25/1731238 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/

Potentially disastrous Rowhammer bitflips can bypass ECC protections
by Peter Reutemann 22 Nov '18

22 Nov '18

'In early 2015, researchers unveiled Rowhammer, a cutting-edge hack that exploits unfixable physical weaknesses in the silicon of certain types of memory chips to transform data they stored. In the 42 months that have passed since then, an enhancement known as error-correcting code (or ECC) available in higher-end chips was believed to be an absolute defense against potentially disastrous bitflips that changed 0s to 1s and vice versa. Research published Wednesday has now shattered that assumption.' -- source: https://arstechnica.com/information-technology/2018/11/potentially-disastro… 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/

Have We Reached Peak Silicon Valley?
by Lawrence D'Oliveiro 21 Nov '18

21 Nov '18

From <https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=121638…>: ... global smartphone sales saw their first year-on-year fall in history at the end of 2017. Apple seemed unaffected at the time, but its latest quarterly results now show falls in unit sales, as a result of which it will stop reporting them in future. >From beginnings that we might date to around the mid-1970s, PC sales (and development) went on an uninterrupted upward curve right through the 1990s, only starting to stutter around about the 2000s. The smartphone revolution, even if it includes the Symbian era and not just Android and Apple, has not lasted quite as long. So what new information-processing technology will ignite the mass market next? If any?

Germany Proposes Rules For Home Router Security
by Lawrence D'Oliveiro 21 Nov '18

21 Nov '18

The federal German body responsible for information security has published some recommendations for how consumers’ internet routers should behave by default, including limiting the initially-enabled services, requiring firewall functionality, and mandating the deletion of all personal data on a factory reset <https://www.theregister.co.uk/2018/11/20/germany_versus_openwrt_ccc/>. This looks like a welcome first step, even if some argue it doesn’t go far enough.

Microsoft Disputing Its NZ Tax Payments
by Lawrence D'Oliveiro 19 Nov '18

19 Nov '18

The IRD is demanding that Microsoft NZ pay more tax <https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=121627…>. This is over the whole notorious business of “transfer pricing”, where sales by multinational corporations are recorded in jurisdictions where they attract less tax, rather than where the customers are located. Looks like there have already been some changes to this, though obviously the dispute would be over whether those changes are enough: From February 2018, the local unit's accounts were extended to include the distribution of computer software and hardware, having previously covered marketing. The change effectively means local product sales are being captured. Concomitant with this: The changes to Microsoft's revenue recognition also seem to route GST through the local unit, with GST payments of $8.1 million in the year ended June 30, compared to just $13,441 a year earlier. Man, that’s quite a jump. All of Microsoft’s NZ customers incurring just $13,441 in GST over an entire year ...

A little collection of cool unix terminal/console/curses tools
by Peter Reutemann 19 Nov '18

19 Nov '18

'Kristof Kovacs: Just a list of 20 (now 28) tools for the command line. Some are little-known, some are just too useful to miss, some are pure obscure -- I hope you find something useful that you weren't aware of yet! Use your operating system's package manager to install most of them. (Thanks for the tips, everybody!)

Mark Shuttleworth Reveals Ubuntu 18.04 Will Get a 10-Year Support Lifespan
by Peter Reutemann 18 Nov '18

18 Nov '18

'At the OpenStack Summit in Berlin last week, Ubuntu Linux founder Mark Shuttleworth said in a keynote that Ubuntu 18.04 Long Term Support (LTS) support lifespan would be extended from five years to 10 years. "I'm delighted to announce that Ubuntu 18.04 will be supported for a full 10 years," said Shuttleworth, "In part because of the very long time horizons in some of industries like financial services and telecommunications but also from IoT where manufacturing lines for example are being deployed that will be in production for at least a decade." ZDNet reports: Ubuntu 18.04 released in April 2018. While the Ubuntu desktop gets most of the ink, most of Canonical's dollars comes from server and cloud customers. It's for these corporate users Canonical first extended Ubuntu 12.04 security support, then Ubuntu 14.04's support, and now, preemptively, Ubuntu 18.04. In an interview after the keynote, Shuttleworth said Ubuntu 16.04, which is scheduled to reach its end of life in April 2021, will also be given a longer support life span. When it comes to OpenStack, Shuttleworth promised again to support versions of OpenStack dating back to 2014's IceHouse. Shuttleworth said, "What matters isn't day two, what matters is day 1,500." He also doubled-down on Canonical's promise to easily enable OpenStack customers to migrate from one version of OpenStack to another. Generally speaking, upgrading from one version of OpenStack is like a root canal: Long and painful but necessary. With Canonical OpenStack, you can step up all the way from the oldest supported version to the newest one with no more than a second of downtime.

Uber Joins Linux Foundation Cementing Commitment To Open Source Tools
by Peter Reutemann 15 Nov '18

15 Nov '18

'At the 2018 Uber Open Summit, Uber announced it was joining the Linux Foundation as a Gold Member, making a firm commitment to using and contributing to open source tools. TechCrunch reports: Uber CTO Thuan Pham sees the Linux Foundation as a place for companies like his to nurture and develop open source projects. "Open source technology is the backbone of many of Uber's core services and as we continue to mature, these solutions will become ever more important," he said in a blog post announcing the partnership. "Uber has made significant investments in shared software development and community collaboration through open source over the years, including contributing the popular open source project Jaeger, a distributed tracing system, to the Linux Foundation's Cloud Native Computing Foundation in 2017," an Uber spokesperson told TechCrunch. As the report mentions, it took the ride-hailing service a long time for them to join the Linux Foundation. "Uber has been long known for making use of open source in its core tools working on over 320 open source projects and repositories from 1500 contributors involving over 70,000 commits, according to data provided by the company," reports TechCrunch.' -- source: https://linux.slashdot.org/story/18/11/15/226212 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/
