When Adobe Stopped Flash Content, It Also Stopped A Chinese Railroad
by Peter Reutemann 25 Jan '21

25 Jan '21

'Jalopnik shares a story for our times: Adobe's Flash, the web browser plug-in that powered so very many crappy games, confusing interfaces, and animated icons of the early web like Homestar Runner is now finally gone, after a long, slow, protracted death. For most of us, this just means that some goofy webgame you searched for out of misplaced nostalgia will no longer run. For a select few in China, though, the death of Flash meant being late to work, because the city of Dalian in northern China was running their railroad system on it. Yes, a railroad, run on Flash, the same thing used to run "free online casinos" and knockoff Breakout games in mortgage re-fi ads... Hell, YouTube used to run on Flash until 2015. It wasn't all stupid little web games but, that said, I can't for the life of me fathom why anyone would want to run a freaking railroad network on it, with physical, multi-ton moving railcars full of human beings on it. So, when Adobe finally killed Flash-based content from running, this Tuesday Dalian's railroad network found itself ground to a halt for 20 hours. The railroad's technicians did get everything back up and running, but the way they did this is fascinating, too. They didn't switch the rail management system to some other, more modern codebase or software installation; instead, they installed a pirated version of Flash that was still operational. The knockoff version seems to be known as "Ghost Version." This, along with installing an older version of the Flash player to work with the knockoff Flash server setup, "solved" the problem, and the railroad was back up and running.' -- source: https://tech.slashdot.org/story/21/01/24/189207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Chrome 88 Released, Removing Adobe Flash -- and FTP
by Peter Reutemann 24 Jan '21

24 Jan '21

'Google released Chrome 88 this week — and besides improving its dark mode support, they removed support for both Adobe Flash and FTP. PC World calls it "the end of two eras." The most noteworthy change in this update is what's not included. Chrome 88 lays Adobe Flash and the FTP protocol to rest. RIP circa-2000 Internet. Neither comes as a surprise, though it's poetic that they're being buried together. Adobe halted Flash Player downloads at the end of 2020, making good on a promise made years before, and began blocking Flash content altogether a couple weeks later. Removing Flash from Chrome 88 is just Google's way of flushing the toilet. On the other hand, FTP isn't dead, but it is now for Chrome users. The File Transport Protocol has helped users send files across the Internet for decades, but in an era of prolific cloud storage services and other sharing methods, its use has waned. Google started slowly disabling FTP support in Chrome 86, per ZDNet, and now you'll no longer be able to access FTP links in the browser. Look for standalone FTP software instead if you need it, such as FileZilla. That's not all. Mac users should be aware that Chrome 88 drops support for OS X 10.10 (OS X Yosemite). Yosemite released in 2014 and received its last update in 2017... But Google killing Flash and FTP might be the footnotes that hit old-school web users in the feels. Chrome 88 will also block non-encrypted downloads originating from an encrypted page, the article reports. And the Verge notes Chrome also offers less intrusive website permission requests (as an experimental feature enabled from chrome://flags/#permission-chip ), while Bleeping Computer describes Chrome 88's new experimental feature for searching through all your open tabs. And Chrome's blog points out some additional features under the hood: Chrome 88 will heavily throttle chained JavaScript timers for hidden pages in particular conditions. This will reduce CPU usage, which will also reduce battery usage. There are some edge cases where this will change behavior, but timers are often used where a different API would be more efficient, and more reliable.' -- source: https://slashdot.org/story/21/01/23/2018224 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Why AWS Is Forking Elasticsearch and Kibana
by Peter Reutemann 24 Jan '21

24 Jan '21

'Steven J. Vaughan-Nichols writes at ZDNet: When Elastic, makers of the open-source search and analytic engine Elasticsearch, went after Amazon Web Services (AWS) by changing its license from the open-source Apache 2.0-license ALv2) to the non-open-source friendly Server Side Public License, I predicted "we'd soon see AWS-sponsored Elasticsearch and Kibana forks." The next day, AWS tweeted it "will launch new forks of both Elasticsearch and Kibana based on the latest Apache 2.0 licensed codebases." Well, that didn't take long! In a blog post, AWS explained that since Elastic is no longer making its search and analytic engine Elasticsearch and its companion data visualization dashboard Kibana available as open source, AWS is taking action. "In order to ensure open source versions of both packages remain available and well supported, including in our own offerings, we are announcing today that AWS will step up to create and maintain an ALv2-licensed fork of open-source Elasticsearch and Kibana.... AWS brings years of experience working with these codebases, as well as making upstream code contributions to both Elasticsearch and Apache Lucene, the core search library that Elasticsearch is built on — with more than 230 Lucene contributions in 2020 alone... We're in this for the long haul, and will work in a way that fosters healthy and sustainable open source practices — including implementing shared project governance with a community of contributors..." Yet another company, Logz.io, a cloud-monitoring company, and some partners have announced that it will launch a "true" open source distribution for Elasticsearch and Kibana.' -- source: https://news.slashdot.org/story/21/01/23/0245229 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Brad Cox, Creator of Objective-C Programming Language, Dies At 76
by Peter Reutemann 24 Jan '21

24 Jan '21

'We have learned that Brad Cox, computer scientist known mostly for creating the Objective-C programming language with his business partner Tom Love, died on January 2, 2021 at his residence. He was 76. >From a Legacy.com post: Brad was born on May 2, 1944 in Fort Benning, Georgia, to the late Nancy Hinson Cox and Dewey McBride Cox of Lake City, South Carolina. Brad grew up on the family's dairy farm in South Carolina but found himself most interested in science. After graduating from Lake City High School, he received his Bachelor of Science Degree in Organic Chemistry and Mathematics from Furman University, and his Ph.D. from the Department of Mathematical Biology at the University of Chicago, and worked on an early form of neural networks. He soon found himself more interested in computers and got a job at International Telephone and Telegraph (ITT) and later joined Schlumbeger -- Doll Research Labs, and ultimately formed his own Connecticut startup, Productivity Products International (PPI) later named Stepstone. Among his first known software projects, he wrote a PDP-8 program for simulating clusters of neurons. He worked at the National Institutes of Health and Woods Hole Oceanographic Institute before moving into the software profession. Dr. Cox was an entrepreneur, having founded the Stepstone Company together with Tom Love for releasing the first Objective-C implementation. Stepstone hoped to sell "ICPaks" and Dr. Cox focused on building his ICPak libraries and hired a team to continue work on Objective-C, including Steve Naroff. The late Steve Jobs', NeXT, licensed the Objective-C language for it's new operating system, NEXTSTEP. NeXT eventually acquired Objective- C from Stepstone. Objective-C continued to be the primary programming language for writing software for Apple's OS X and iOS.

DDoSers are abusing Microsoft RDP to make attacks more powerful
by Peter Reutemann 24 Jan '21

24 Jan '21

'DDoS-for-hire services are abusing the Microsoft Remote Desktop Protocol to increase the firepower of distributed denial-of-service attacks that paralyze websites and other online services, a security firm said this week. Typically abbreviated as RDP, Remote Desktop Protocol is the underpinning for a Microsoft Windows feature that allows one device to log into another device over the Internet. RDP is mostly used by businesses to save employees the cost or hassle of having to be physically present when accessing a computer. As is typical with many authenticated systems, RDP responds to login requests with a much longer sequence of bits that establish a connection between the two parties. So-called booter/stresser services, which for a fee will bombard Internet addresses with enough data to take them offline, have recently embraced RDP as a means to amplify their attacks, security firm Netscout said. The amplification allows attackers with only modest resources to strengthen the size of the data they direct at targets. The technique works by bouncing a relatively small amount of data at the amplifying service, which in turn reflects a much larger amount of data at the final target. With an amplification factor of 85.9 to 1, 10 gigabytes-per-second of requests directed at an RDP server will deliver roughly 860Gbps to the target. “Observed attack sizes range from ~20 Gbps – ~750 Gbps,” Netscout researchers wrote. “As is routinely the case with newer DDoS attack vectors, it appears that after an initial period of employment by advanced attackers with access to bespoke DDoS attack infrastructure, RDP reflection/amplification has been weaponized and added to the arsenals of so-called booter/stresser DDoS-for-hire services, placing it within the reach of the general attacker population.”' -- source: https://arstechnica.com/information-technology/2021/01/ddosers-are-abusing-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How DNSpooq Attacks Could Poison DNS Cache Records
by Peter Reutemann 24 Jan '21

24 Jan '21

'Earlier this week security experts disclosed details on seven vulnerabilities impacting Dnsmasq, "a popular DNS software package that is commonly deployed in networking equipment, such as routers and access points," reports ZDNet. "The vulnerabilities tracked as DNSpooq, impact Dnsmasq, a DNS forwarding client for *NIX-based operating systems." Slashdot reader Joe2020 shared Help Net Security's quote from Shlomi Oberman, CEO and researcher at JSOF. "Some of the bigger users of Dnsmasq are Android/Google, Comcast, Cisco, Red Hat, Netgear, and Ubiquiti, but there are many more. All major Linux distributions offer Dnsmasq as a package, but some use it more than others, e.g., in OpenWRT it is used a lot, Red Hat use it as part of their virtualization platforms, Google uses it for Android hotspots (and maybe other things), while, for example Ubuntu just has it as an optional package." More from ZDNet: Dnsmasq is usually included inside the firmware of various networking devices to provide DNS forwarding capabilities by taking DNS requests made by local users, forwarding the request to an upstream DNS server, and then caching the results once they arrive, making the same results readily available for other clients without needing to make a new DNS query upstream. While their role seems banal and insignificant, they play a crucial role in accelerating internet speeds by avoiding recursive traffic... Today, the DNSpooq software has made its way in millions of devices sold worldwide [including] all sorts of networking gear like routers, access points, firewalls, and VPNs from companies like ZTE, Aruba, Redhat, Belden, Ubiquiti, D-Link, Huawei, Linksys, Zyxel, Juniper, Netgear, HPE, IBM, Siemens, Xiaomi, and others. The DNSpooq vulnerabilities, disclosed today by security experts from JSOF, are dangerous because they can be combined to poison DNS cache entries recorded by Dnsmasq servers. Poisoning DNS cache records is a big problem for network administrators because it allows attackers to redirect users to clones of legitimate websites... In total, seven DNSpooq vulnerabilities have been disclosed today. Four are buffer overflows in the Dnsmasq code that can lead to remote code execution scenarios, while the other three bugs allow DNS cache poisoning. On their own, the danger from each is limited, but researchers argue they can be combined to attack any device with older versions of the Dnsmasq software... The JSOF exec told ZDNet that his company has worked with both the Dnsmasq project author and multiple industry partners to make sure patches were made available to device vendors by Tuesday's public disclosure.' -- source: https://it.slashdot.org/story/21/01/23/0412253 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Alphabet Shuts Down Loon Internet Balloon Company
by Peter Reutemann 23 Jan '21

23 Jan '21

'Google's parent firm, Alphabet, is done exploring the idea of using a fleet of balloons to beam high-speed internet in remote parts of the world. From a report: The firm said on Thursday evening that it was winding down Loon, a nine-year-old project and a two-and-a-half-year-old spin off firm, after failing to find a sustainable business model and partners for one of its most prominent moonshot projects. The demise of Loon, which assumed spotlight after the project helped restore cell services knocked out by a hurricane in Puerto Rico, comes a year after the Android-maker ended Google Station, its other major connectivity effort to bring internet to the next billion users.' -- source: https://tech.slashdot.org/story/21/01/22/1418212 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel Talks With TSMC, Samsung To Outsource Some Chip Production
by Peter Reutemann 22 Jan '21

22 Jan '21

'Intel has talked with TSMC and Samsung about the Asian companies making some of its best chips, but the Silicon Valley pioneer is still holding out hope for last-minute improvements in its own production capabilities. Bloomberg reports: After successive delays in its chip fabrication processes, Santa Clara, California-based Intel has yet to make a final decision less than two weeks ahead of a scheduled announcement of its plans, according to people familiar with the deliberations. Any components that Intel might source from Taiwan wouldn't come to market until 2023 at the earliest and would be based on established manufacturing processes already in use by other TSMC customers, said the people, asking not to be identified because the plans are private. Talks with Samsung, whose foundry capabilities trail TSMC's, are at a more preliminary stage, the people said. An Intel spokesperson referred to previous comments by Bob Swan, the company's chief executive officer. Swan has promised investors he'll set out his plans for outsourcing and get Intel's production technology back on track when the company reports earnings Jan. 21. [...] TSMC, the largest maker of semiconductors for other companies, is preparing to offer Intel chips manufactured using a 4-nanometer process, with initial testing using an older 5-nanometer process, according to the people. The company has said it will make test production of 4-nanometer chips available in the fourth quarter of 2021 and volume shipments the following year. The Taiwanese company expects to have a new facility in Baoshan operational by the end of this year, which can be converted to production for Intel if required, one of the people said. TSMC executives previously said the new Baoshan unit would house a research center with 8,000 engineers. While Intel has outsourced production of lower-end chips before, it has kept the manufacturing of its best semiconductors in-house, considering it a competitive strength. Its engineers have historically tailored their designs to the company's manufacturing processes, making a shift to outsourcing of flagship products unthinkable in the past. As the provider of 80% of personal computer and server processors globally, Intel produces hundreds of millions of chips each year. That scale dictates that any potential supplier must create new capacity to accommodate Intel.' -- source: https://hardware.slashdot.org/story/21/01/08/2215226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
