AI Magic Comes At A Price

Interview with a software developer <https://www.theregister.com/2020/06/19/generative_adversarial_networks_are_…> about the pitfalls of using Generative Adversarial Networks (GANs) for the specific task of adding colour to old monochrome images. You can get them to produce good results most of the time, then every now and then they will go wrong in some weird and unsettling way: "GANs would spit out very weird specific glitches like odd splashes of colour on someone's hand and it made them look creepy," he told us. In some examples, people have turned an eerie alien green. And trying to tweak things manually can just as easily make things worse as better. He offers an open-source version of his product here <https://github.com/jantic/DeOldify>. Note the Jupyter notebooks. ;)

Lawsuit vs. Western Digital wants to end any use of SMR in NAS drives
by Peter Reutemann 18 Jun '20

18 Jun '20

'Law firm Hattis & Lukacs has filed an amendment to its class-action lawsuit against Western Digital for including SMR technology in its WD Red line of NAS drives. The amendment adds five more named plaintiffs from five new states, and it includes significant additional technical detail. If you aren't up to date on the SMR saga, this is one article in an ongoing series. The short version: SMR—Shingled Magnetic Recording—is a relatively new hard drive recording technology that allows higher data densities. It does so by laying down overlapping tracks—like shingles on a roof—with a write head that's wider than the read head. Unfortunately, this technology makes rewriting existing disk sectors agonizingly slow in many cases—rewriting a single 4KiB sector will generally mean needing to both read and rewrite an entire 256MiB zone. The original American class-action suit (there's a Canadian one as well) had a single named plaintiff, Wisconsin's Nicholas Malone. The amendment features five new plaintiffs, each from a different state, and tells each plaintiff's story in detail. New York plaintiff Steve Gravel's story is particularly wince-inducing—he wasn't just using the drives for photo and movie storage; he had an iSCSI target on his QNAP NAS, and the performance decrease when he replaced CMR drives with SMR was, as you might expect, terrible.' -- source: https://arstechnica.com/information-technology/2020/06/lawsuit-vs-western-d… 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 pushes “text fragment links” with new Chrome extension
by Peter Reutemann 18 Jun '20

18 Jun '20

'Google has been cooking up an extension to the URL standard called "Text Fragments." The new link style will allow you to link not just to a page but to specific text on a page, which will get scrolled to and highlighted automatically once the page loads. It's like an anchor link, but with highlighting and creatable by anyone. The feature has actually been supported in Chrome since version 80, which hit the stable channel in February. Now a new extension from Google makes it easy to create this new link type, which will work for anyone else using Chrome on desktop OSes and Android. Google has proposed the idea to the W3C and hopes other browsers will adopt it, but even if they don't, the links are backward-compatible.' -- source: https://arstechnica.com/gadgets/2020/06/google-pushes-text-fragment-links-w… 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/

Massive Spying on Users of Google's Chrome Shows New Security Weakness
by Peter Reutemann 18 Jun '20

18 Jun '20

'A newly discovered spyware effort attacked users through 32 million downloads of extensions to Google's market-leading Chrome web browser, researchers at Awake Security told Reuters, highlighting the tech industry's failure to protect browsers as they are used more for email, payroll and other sensitive functions. From a report: Google said it removed more than 70 of the malicious add-ons from its official Chrome Web Store after being alerted by the researchers last month. "When we are alerted of extensions in the Web Store that violate our policies, we take action and use those incidents as training material to improve our automated and manual analyses," Google spokesman Scott Westover told Reuters. Most of the free extensions purported to warn users about questionable websites or convert files from one format to another. Instead, they siphoned off browsing history and data that provided credentials for access to internal business tools. Based on the number of downloads, it was the most far-reaching malicious Chrome store campaign to date, according to Awake co-founder and chief scientist Gary Golomb.' -- source: https://yro.slashdot.org/story/20/06/18/1341219 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/

AWS Said It Mitigated a 2.3 Tbps DDoS Attack, the Largest Ever
by Peter Reutemann 17 Jun '20

17 Jun '20

'Amazon said its AWS Shield service mitigated the largest DDoS attack ever recorded, stopping a 2.3 Tbps attack in mid-February this year. The incident was disclosed in the company's AWS Shield Threat Landscape [PDF], a report detailing web attacks mitigated by Amazon's AWS Shield protection service. The report didn't identify the targeted AWS customer but said the attack was carried out using hijacked CLDAP web servers and caused three days of "elevated threat" for its AWS Shield staff. [...] The previous record for the largest DDoS attack ever recorded was of 1.7 Tbps, mitigated by NETSCOUT Arbor in March 2018. Before that, the biggest DDoS attack ever recorded was a 1.3 Tbps DDoS attack that hit GitHub, a month before, in February 2018.' -- source: https://it.slashdot.org/story/20/06/17/1958227 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 Medical Device Maker Threatens iFixit Over Ventilator Repair Project
by Peter Reutemann 17 Jun '20

17 Jun '20

'STERIS Corporation, a company that makes sterilization and other medical equipment, sent a letter to iFixit claiming their online database of repair manuals for ventilators and medical equipment violates their copyrights. Motherboard reports: "It has come to my attention that you have been reproducing certain installation and maintenance manuals relating to our products, documentation which is protected by copyright law," the letter said. The letter then went on to tell [Kyle Wiens, CEO of iFixit] to remove all Steris copyrighted material from the iFixit website within 10 days of the letter. As Motherboard reported in March, major manufacturers of medical devices have long made it difficult for their devices to be repaired through third party repair professionals. Manufacturers have often lobbied against right to repair legislation and many medical devices are controlled by artificial "software locks" that allow only those with authorization to make modifications. "I'm disappointed that Steris is resorting to legal threats to stop hospitals from having access to information about how to maintain critical sterilization equipment during a pandemic," Wiens told Motherboard in an email. "No manufacturer should be stopping hospitals from repairing their equipment," Wiens said. "The best way to ensure patient safety is to make sure that equipment is being maintained regularly using the manufacturer's recommended procedures. The only way to do that is if hospitals have up to date manuals." With regards to the letter sent by Steris, Wiens said iFixit has not removed any material from its website. "We explained to Steris that what we did is a lawful and protected fair use under the U.S. Copyright act," Wiens said. "iFixit is protected by Section 512 of the Digital Millennium Copyright Act, which allows online platforms to host content contributed by users provided they comply with the Act's requirements, which iFixit does," a letter to Steris from the Electronic Frontier Foundation on behalf of iFixit said.' -- source: https://science.slashdot.org/story/20/06/17/2013232 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/

Zoom To Launch End-to-End Encryption For All Users -- Not Just Paid Accounts
by Peter Reutemann 17 Jun '20

17 Jun '20

'Weeks after Zoom said it will offer end-to-end encryption to only paying customers -- a move that was received poorly by several privacy and security advocates, the popular video calling software said on Wednesday it is making some amendments: We are also pleased to share that we have identified a path forward that balances the legitimate right of all users to privacy and the safety of users on our platform. This will enable us to offer E2EE (end-to-end encryption) as an advanced add-on feature for all of our users around the globe -- free and paid -- while maintaining the ability to prevent and fight abuse on our platform. To make this possible, Free/Basic users seeking access to E2EE will participate in a one-time process that will prompt the user for additional pieces of information, such as verifying a phone number via a text message. Many leading companies perform similar steps on account creation to reduce the mass creation of abusive accounts. We are confident that by implementing risk-based authentication, in combination with our current mix of tools -- including our Report a User function -- we can continue to prevent and fight abu' -- source: https://yro.slashdot.org/story/20/06/17/1631222 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/

CEO of Open Technology Fund Resigns After Closed-Source Lobbying Effort
by Peter Reutemann 17 Jun '20

17 Jun '20

'The head of the Open Technology Fund (OTF) Corporation, which funds internet freedom projects and technologies, resigned Wednesday because she said she became aware of a lobbying effort that would push the group's funds toward closed-source tools rather than the open-source ones it has traditionally championed. From a report: In a resignation email sent to an OTF mailing list, Libby Liu, the inaugural OTF CEO, mentioned that the Trump administration had recently sworn in Michael Peck as the new head of the U.S. Agency for Global Media (USAGM), which is the OTF's grantor. She said that she learned of lobbying efforts to push money to closed-source tools. "As you all know, OTF's flexible, transparent, and competitive funding model has been essential to our success in supporting the most secure and effective internet freedom technologies and innovative projects available," she wrote. "I have become aware of lobbying efforts to convince the new USAGM [U.S. Agency for Global Media] CEO to interfere with the current FY2020 OTF funding stream and redirect some of our resources to a few closed-source circumvention tools."' -- source: https://news.slashdot.org/story/20/06/17/1946213 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/

Mozilla, EFF, 19,000 Citizens Urge Zoom To Reverse End-to-End Encryption Decision
by Peter Reutemann 16 Jun '20

16 Jun '20

'Mozilla, Electronic Frontier Foundation (EFF), and more than 19,000 internet users today urged Zoom CEO Eric Yuan to reverse his decision to deny end-to-end encryption to users of its free service end-to-end encryption, saying it puts activists and other marginalized groups at risk. Earlier this month, Zoom announced it will offer end-to-end encryption, but only to those who pay. From a statement: The pressure to reverse the decision comes as racial justice activists are using tools like Zoom to organize protests. Without end-to-end encryption, information shared in their online meetings could be intercepted -- a concern that has been legitimized by both recent actions by law enforcement and a long-term history of discriminatory policing. Mozilla and EFF today are presenting an open letter to Yuan, co-signed by 19,000 people, maintaining that privacy and best-in-class security should be the default, not something that only the wealthy or businesses can afford.

Ripple20 Vulnerabilities Will Haunt the IoT Landscape For Years To Come
by Peter Reutemann 16 Jun '20

16 Jun '20

'Cyber-security experts have revealed today 19 vulnerabilities in a small library designed in the 90s that has been widely used and integrated into countless of enterprise and consumer-grade products over the last 20+ years. From a report: Affected products include smart home devices, power grid equipment, healthcare systems, industrial gear, transportation systems, printers, routers, mobile/satellite communications equipment, data center devices, commercial aircraft devices, various enterprise solutions, and many others. Experts now fear that all products using this library will most likely remain unpatched due to complex or untracked software supply chains. Problems arise from the fact that the library was not only used by equipment vendors directly but also integrated into other software suites, which means that many companies aren't even aware that they're using this particular piece of code, and the name of the vulnerable library doesn't appear in their code manifests.' -- source: https://it.slashdot.org/story/20/06/16/179230 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/
