Chances of destructive BlueKeep exploit rise with new explainer posted online
by Peter Reutemann 23 Jul '19

23 Jul '19

'A security researcher has published a detailed guide that shows how to execute malicious code on Windows computers still vulnerable to the critical BlueKeep vulnerability. The move significantly lowers the bar for writing exploits that wreak the kinds of destructive attacks not seen since the WannaCry and NotPetya attacks of 2017, researchers said. As of three weeks ago, more than 800,000 computers exposed to the Internet were vulnerable to the exploit, researchers from security firm BitSight said last week. Microsoft and a chorus of security professionals have warned of the potential for exploits to sow worldwide disruptions. The risk of the bug, found in Microsoft's implementation of the remote desktop protocol, stems from the ability for attacks to spread from one vulnerable computer to another with no interaction required of end users.' -- source: https://arstechnica.com/information-technology/2019/07/explainer-for-exploi… May you live in interesting times (as a Windows users)...

cycling through windows of same application
by Peter Reutemann 23 Jul '19

23 Jul '19

Hi everyone Just learned something new by accident... ;-) Using "Alt+`" (the key above Tab), you can limit the cycling to the windows of that application, e.g., all Firefox or LibreOffice Writer/Calc windows in a workspace. Useful alternative to "Alt+Tab" which cycles through all Windows in a workspace. >From the looks of it, cycling through multiple terminal windows doesn't work. I presume, this is because they are different processes rather than child windows. Tested on Linux Mint 19.1 MATE desktop. -- source: https://askubuntu.com/questions/1160167 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/

SUSE Names Melissa Di Donato New CEO
by Peter Reutemann 22 Jul '19

22 Jul '19

'Melissa Di Donato, SAP's former COO, has been named SUSE's new CEO. ZDNet reports: London-based Di Donato is a well-known technology leader. In particular, she has a proven track record in sales and business operations. Besides being SAP's COO, she was also the company's chief revenue officer. In SAP's latest quarter, SAP saw an increase of 11% year-over-year revenues. Much of that came from the cloud -- where SAP saw 40% year-over-year growth. SAP's cloud is built on SUSE's Linux servers and OpenStack cloud. Di Donato succeeds Nils Brauckmann. While officially Brauckmann is retiring, there seems to be more to the story. On LinkedIn, Brauckmann wrote: "I care very deeply for the SUSE business and its employees, and this difficult decision is based entirely on personal reasons. I am pleased to be handing over the reins to such a talented and accomplished leader as Melissa Di Donato." In his SUSE statement, Brauckman added: "She is a proven and dynamic change agent, and many of her achievements have occurred in subscription businesses that exist in high-growth cloud environments." In April, then-CEO Nils Brauchmann said his company would soon be the largest independent Linux company. This comes after Brauckmann delivered eight years of continuous expansion during his tenure, including record-breaking revenues in FY18, reports ZDNet. "Under Di Donato's leadership, SUSE will continue to focus on growth and expansion. What that means is she's expected to advance SUSE's core business and emerging technologies, both organically and through add-on acquisitions."' -- source: https://linux.slashdot.org/story/19/07/22/2038259 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/

Dropbox Brings Back Support For ZFS, XFS, Btrfs And eCryptFS On Linux
by Peter Reutemann 22 Jul '19

22 Jul '19

'Speaking of Dropbox, the online storage cloud service has enabled support for ZFS and XFS on 64-bit Linux systems, and eCryptFS and Btrfs on all Linux systems. The move comes after it recently pulled support for all file storage systems on Linux except Ext4. From a report: Dropbox stopped supporting folder syncing to drives with filesystems it deemed "uncommon", which on Linux meant anything but Ext4, upsetting quite a few users. The reason cited for this was that "a supported file system is required as Dropbox relies on extended attributes (X-attrs) to identify files in the Dropbox folder and keep them in sync", which doesn't really make sense since there are many filesystems that support xattr (extended attributes) on Linux. After this change was announced, various workarounds started to appear online, including one that I posted on Linux Uprising. There was even a new unofficial, open source Dropbox client developed for this reason (which is also much lighter than the official client by the way). But this didn't last long though, as last week, the Dropbox 77.3.127 beta changelog says that Dropbox has added back support for ZFS (on 64-bit systems only), XFS (on 64bit systems only), Btrfs and eCryptFS.' -- source: https://hardware.slashdot.org/story/19/07/22/1534200 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/

This pixel tracking demo shows how easy it is to make a creepy surveillance tool
by Peter Reutemann 19 Jul '19

19 Jul '19

'The Superhuman controversy from earlier this month, in which a former Silicon Valley exec blew the lid off a series of controversial email surveillance tools offered by the up-and-coming startup, has prompted a bit of soul searching among those in the tech industry. But in twisted fashion, the public blasting of a company like Superhuman has been the tech equivalent of opening Pandora’s Box, unearthing all sorts of free and easily available tools that have done this for years and can be employed by anyone with just the tiniest shred of tech savvy. For instance, an open source, Python-based web tool called Supertracker has popped up on Github, courtesy of Delian Asparouhov, an investor with the venture capital firm Founder’s Fund. It lets anyone create their own tracking pixel, coyly disguised as either a transparent image, an image of the pokémon pikachu, or a not-so-subtle magnifying glass. Creating it is as easy as inputting a user name, picking a tracking pixel image, and hitting the enter key. From there, you can save the image, paste it in the body of any email, and send it off. Whoever opens it will have the when and even the where transmitted back to you. Of course, you can do similar styles of tracking with any number of available Superhuman competitors and browser extensions. But Asparouhov’s tool has the added benefit of walking you through the process step by step and laying out just how simple it is to siphon away this kind of sensitive info with a few simple lines of code. (He also outlines some good defenses against this type of surveillance.)

China's Tech Giants Have a Second Job: Helping Beijing Spy on Its People
by Peter Reutemann 19 Jul '19

19 Jul '19

'Tencent and Alibaba are among the firms that assist authorities in hunting down criminal suspects, silencing dissent and creating surveillance cities. From a report: Alibaba Group's sprawling campus has collegial workspaces, laid-back coffee bars and, on the landscaped grounds, a police outpost. Employees use the office to report suspected crimes to the police, according to people familiar with the operation. Police also use it to request data from Alibaba for their own investigations, these people said, tapping into the trove of information the tech giant collects through its e-commerce and financial-payment networks. In one case, the police wanted to find out who had posted content related to terrorism, said a former Alibaba employee. "They came to me and asked me for the user ID and information," he recalled. He turned it over. The Chinese government is building one of the world's most sophisticated, high-tech systems to keep watch over its citizens, including surveillance cameras, facial-recognition technology and vast computers systems that comb through terabytes of data. Central to its efforts are the country's biggest technology companies, which are openly acting as the government's eyes and ears in cyberspace. Companies including Alibaba Group Holding, Tencent Holdings and Baidu, are required to help China's government hunt down criminal suspects and silence political dissent. Their technology is also being used to create cities wired for surveillance.' -- source: https://yro.slashdot.org/story/19/07/19/1443207 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/

Huawei Says Hongmeng OS Isn't Designed as an Android Replacement
by Peter Reutemann 19 Jul '19

19 Jul '19

'Huawei reportedly wants to keep using Google's Android operating system in its phones instead of jumping to its self-developed Hongmeng system. From a report: Company senior vice president Catherine Chen told reporters in Brussels this week that the Hongmeng OS isn't even designed for phones, according to Chinese state news agency Xinhua. Chen apparently said Hongmeng is for industrial use, noting that it contains far fewer lines of code than a phone OS, and has much lower latency than a phone, meaning it can process a very high volume of data messages with little delay. Latest episode in a confusing narrative about what Huawei even intends to do. The company's executives have previously said on record that its homegrown operating system is designed to replace Android on its handsets. One executive said the operating system would be released by last month -- a target that Huawei has missed.' -- source: https://tech.slashdot.org/story/19/07/19/1524253 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/

A Rust-Based TLS Library Outperformed OpenSSL in Almost Every Category
by Peter Reutemann 19 Jul '19

19 Jul '19

'A tiny and relatively unknown TLS library written in Rust, an up-and-coming programming language, outperformed the industry-standard OpenSSL in almost every major category. From a report: The findings are the result of a recent four-part series of benchmarks carried out by Joseph Birr-Pixton, the developer behind the Rustls library. The findings showed that Rustls was 10% faster when setting up and negotiating a new server connection, and between 20 and 40% faster when setting up a client connection. But while handshake speeds for new TLS connections are important, most TLS traffic relies on resuming previously negotiated handshakes. Here, too, Rustls outperformed the aging OpenSSL, being between 10 and 20% in resuming a connection on the server-side, and being between 30 and 70% quicker to resume a client connection. Furthermore, Rustls also fared better in sheer bulk performance -- or the speed at which data is transferred over the TLS connection. Birr-Pixton said Rustls could send data 15% faster than OpenSSL, and receive it 5% faster as well.' -- source: https://tech.slashdot.org/story/19/07/19/1546224 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/

My browser, the spy: How extensions slurped up browsing histories from 4M users
by Peter Reutemann 18 Jul '19

18 Jul '19

'When we use browsers to make medical appointments, share tax returns with accountants, or access corporate intranets, we usually trust that the pages we access will remain private. DataSpii, a newly documented privacy issue in which millions of people’s browsing histories have been collected and exposed, shows just how much about us is revealed when that assumption is turned on its head. DataSpii begins with browser extensions—available mostly for Chrome but in more limited cases for Firefox as well—that, by Google's account, had as many as 4.1 million users. These extensions collected the URLs, webpage titles, and in some cases the embedded hyperlinks of every page that the browser user visited. Most of these collected Web histories were then published by a fee-based service called Nacho Analytics, which markets itself as “God mode for the Internet” and uses the tag line “See Anyone’s Analytics Account.” Web histories may not sound especially sensitive, but a subset of the published links led to pages that are not protected by passwords—but only by a hard-to-guess sequence of characters (called tokens) included in the URL. Thus, the published links could allow viewers to access the content at these pages. (Security practitioners have long discouraged the publishing of sensitive information on pages that aren't password protected, but the practice remains widespread.)' -- source: https://arstechnica.com/information-technology/2019/07/dataspii-inside-the-… 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/
