Speed Up Microsoft Teams By Bypassing Antivirus Checks
by Lawrence D'Oliveiro 13 Jul '21

13 Jul '21

Microsoft’s official recommendation <https://github.com/MicrosoftDocs/OfficeDocs-SkypeForBusiness/blob/9df8f4069…> for improving the performance of Teams on Windows is to exclude it from antivirus checks: Add the following Teams programs to your antivirus safe list. %localappdata%\Microsoft\Teams\current\Teams.exe %localappdata%\Microsoft\Teams\Update.exe Add the following Teams folders to your antivirus safe list. %localappdata%\Microsoft\Teams %appdata%\Microsoft\Teams| Because antivirus software only exists to slow your system down, right?

Libre-SOC's Open Hardware 180nm ASIC Submitted To IMEC for Fabrication
by Peter Reutemann 11 Jul '21

11 Jul '21

'"We're building a chip. A fast chip. A safe chip. A trusted chip," explains the web page at Libre-SOC.org. "A chip with lots of peripherals. And it's VPU. And it's a 3D GPU... Oh and here, have the source code." And now there's big news, reports long-time Slashdot reader lkcl: Libre-SOC's entirely Libre 180nm ASIC, which can be replicated down to symbolic level GDS-II with no NDAs of any kind, has been submitted to IMEC for fabrication. It is the first wholly-independent Power ISA ASIC outside of IBM to go Silicon in 12 years. Microwatt went to Skywater 130nm in March; however, it is also developed by IBM, as an exceptionally well-made Reference Design, which Libre-SOC used for verification. Whilst it would seem that Libre-SOC is jumping on the chip-shortage era's innovation bandwagon, Libre-SOC has actually been in development for over three and a half years so far. It even pre-dates the OpenLane initiative, and has the same objectives: fully automated HDL to GDS-II, full transparency and auditability with Libre VLSI tools Coriolis2 and Libre Cell Libraries from Chips4Makers. With €400,000 in funding from the NLNet Foundation [a long-standing non-profit supporting privacy, security, and the "open internet"], plus an application to NGI Pointer under consideration, the next steps are to continue development of Draft Cray-style Vectors (SVP64) to the already supercomputer-level Power ISA, under the watchful eye of the upcoming OpenPOWER ISA Workgroup.' -- source: https://hardware.slashdot.org/story/21/07/10/0154220 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/

Microsoft Edge Beats Firefox To Become the Third-Most Popular Browser
by Peter Reutemann 11 Jul '21

11 Jul '21

'"New data from Statcounter shows that Edge has now overtaken established rival Firefox in the rankings," reports TechRadar: In recent months, the pair have been neck-and-neck, but Microsoft's browser has now put daylight between itself and Firefox. Figures for June suggest Microsoft Edge now holds 3.4% of the browser market, while Firefox has slipped to 3.29%, continuing a downward trajectory that has seen the browser either lose or maintain market share in ten of the last twelve months. The change pushes Edge into third position in the browser rankings, behind only Chrome (65.27%) and Safari (18.34%). Launched in January 2020, the new Chromium-based Edge got off to a slow start, but began to gather momentum as the year progressed. Since last summer, the browser's market share has more than tripled. The increase in adoption can be attributed in part to renewed marketing efforts, but also to improvements that brought the experience in line with other modern web browsers. That may be true, but the article also acknowledges that it was just last month that Microsoft began rolling out Edge to all Windows PCs (via Windows 10 updates), "expanding the install base by millions almost overnight. "Now, Microsoft is doing everything in its power to encourage users to abandon Internet Explorer in favor of Edge, such as removing support for Microsoft 365 web apps and automatically launching certain web pages in the new browser."' -- source: https://news.slashdot.org/story/21/07/10/0353201 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/

Google's Unfair Performance Advantage in Chrome
by Peter Reutemann 10 Jul '21

10 Jul '21

'Google Chrome for Android has a feature that gives Google Search an unfair advantage over its competition. Sure, it's the default search engine and that's a huge hurdle to overcome for any competitor. However, Chrome also reserves a performance-boosting feature for Google Search exclusively. I recently poked around in the Chromium project source code; the open-source foundation for Google's Chrome web browser. The Chromium project is co-developed by Google, and other corporate and individual contributors. The project is managed and controlled by Google, however. I was looking for something else when I stumbled upon a feature called PreconnectToSearch. When enabled, the feature preemptively opens and maintains a connection to the default search engine. The preconnection feature resolves the domain name, and negotiates and sets up a secure connection to the server. All these things take time and they must happen before the search engine can receive the users' search queries. Preempting these steps can save a dozen seconds on a slow network connection or half a second on a fast connection. This optimization can yield a nice performance boost for Google's customers. Assuming the connection only requires a trivial amount of processing power and network bandwidth, of course. Setting up the connection early can be wasteful or slow down the loading of other pages if the user isn't going to search the web. There's just one small catch: Chromium checks the default search engine setting, and only enables the feature when it's set to Google Search. This preferential treatment means no other search engine can compete with Google Search on the time it takes to load search results. Every competitor must wait until the user has started to type a search query before Chrome will establish a connection.' -- source: https://tech.slashdot.org/story/21/07/09/2056209 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/

Firefox Extends Privacy and Security of Canadian Internet Users With By-default DNS-over-HTTPS Rollout in Canada
by Peter Reutemann 09 Jul '21

09 Jul '21

'In a few weeks, Firefox will start the by-default rollout of DNS over HTTPS (or DoH for short) to its Canadian users in partnership with local DoH provider CIRA, the Canadian Internet Registration Authority. From a report: DoH will first become a default for 1% of Canadian Firefox users on July 20 and will gradually reach 100% of Canadian Firefox users in late September 2021 -- thereby further increasing their security and privacy online. This follows the by-default rollout of DoH to US users in February 2020. As part of the rollout, CIRA joins Mozilla's Trusted Recursive Resolver (TRR) Program and becomes the first internet registration authority and the first Canadian organization to provide Canadian Firefox users with private and secure encrypted Domain Name System (DNS) services.' -- source: https://news.slashdot.org/story/21/07/08/1732203 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/

Kaspersky Password Manager Fixes Flaw That Generated Easily Bruteforced Passwords
by Peter Reutemann 09 Jul '21

09 Jul '21

'ZDNet reports: Suppose you are in the business of generating passwords, it would probably be a good idea to use an additional source of entropy other than the current time, but for a long time, that's all Kaspersky Password Manager (KPM) used. In a blog post to cap off an almost two year saga, Ledger Donjon head of security research Jean-Baptiste Bedrune showed KPM was doing just that. "Kaspersky Password Manager used a complex method to generate its passwords. This method aimed to create passwords hard to break for standard password crackers. However, such method lowers the strength of the generated passwords against dedicated tools," Bedrune wrote. One of the techniques used by KPM was to make letters that are not often used appear more frequently, which Bedrune said was probably an attempt to trick password cracking tools. "Their password cracking method relies on the fact that there are probably 'e' and 'a' in a password created by a human than 'x' or 'j', or that the bigrams 'th' and 'he' will appear much more often than 'qx' or 'zr'," he said. "Passwords generated by KPM will be, on average, far in the list of candidate passwords tested by these tools. If an attacker tries to crack a list of passwords generated by KPM, he will probably wait quite a long time until the first one is found. This is quite clever." The flip side was that if an attacker could deduce that KPM was used, then the bias in the password generator started to work against it. "If an attacker knows a person uses KPM, he will be able to break his password much more easily than a fully random password. Our recommendation is, however, to generate random passwords long enough to be too strong to be broken by a tool." The big mistake made by KPM though was using the current system time in seconds as the seed into a Mersenne Twister pseudorandom number generator. "It means every instance of Kaspersky Password Manager in the world will generate the exact same password at a given second," Bedrune said. Because the program has an animation that takes longer than a second when a password is created, Bedrune said it could be why this issue was not discovered. "The consequences are obviously bad: every password could be bruteforced," he said. Bedrune added due to sites often showing account creation time, that would leave KPM users vulnerable to a bruteforce attack of around 100 possible passwords. "Kaspersky was informed of the vulnerability in June 2019, and released the fix version in October that same year," adds ZDNet. "In October 2020, users were notified that some passwords would need to be generated, with Kaspersky publishing its security advisory on 27 April 2021." "All public versions of Kaspersky Password Manager liable to this issue now have a new logic of password generation and a passwords update alert for cases when a generated password is probably not strong enough," the security company said.' -- source: https://it.slashdot.org/story/21/07/08/2116252 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/

Endian Wars: Linus Has Spoken
by Lawrence D'Oliveiro 06 Jul '21

06 Jul '21

The Rust language continues to make progress for use in the Linux kernel <https://www.theregister.com/2021/07/05/rust_for_linux_kernel_project/>. The article ends with a comment from Linus Torvalds about the old “endian wars” which have been a feature of the computing landscape since byte addressability became common: should the bytes of a number be arranged in big-endian order (most significant end at the lowest address) or little-endian (least significant end at the lowest address)? In the latest patches, Ojeda proposed to use big-endian order for long symbols in the kernel symbol table, needed because Rust symbols "can become quite long due to namespacing introduced by modules, types, traits, generics." Torvalds responded: "Why is this in big-endian order? Let's just try to kill big-endian data, it's disgusting and should just die already... networking has legacy reasons from the bad old days when byte order wars were still a thing, but those days are gone." Having used both kinds of computer architectures over the years, I agree. Little-endian ordering is more mathematically consistent.

Open Source Audio Editor Audacity Has Become 'Spyware'
by Peter Reutemann 06 Jul '21

06 Jul '21

'Anyone deciding to download the free and open-source audio editor Audacity is being warned that the software may now be classified as spyware due to recent updates to its privacy policy. From a report: Audacity has been around for over 21 years and classes as the world's most popular audio editing software. On April 30, the Muse Group acquired Audacity with the promise that the software would "remain forever free and open source." However, as FOSS Post reports, last week the Audacity privacy policy page was updated and introduced a number of personal data collection clauses. The data collected includes OS version and name, user country based on IP address, the CPU being used, data related to Audacity error codes and crash reports, and finally "Data necessary for law enforcement, litigation and authorities' requests (if any)." The personal data collected can be shared with Muse Group employees, auditors, advisors, legal representatives and "similar agents," potential company buyers, and "any competent law enforcement body, regulatory, government agency, court or other third party where we believe disclosure is necessary (i) as a matter of applicable law or regulation, or (ii) to exercise, establish or defend our legal rights."' -- source: https://yro.slashdot.org/story/21/07/05/2155212 How long before a fork occurs that will strip out these bits?

Infinidash: The Most Amazing Amazon Web Services Product ... That Never Was
by Lawrence D'Oliveiro 05 Jul '21

05 Jul '21

It all started with one person wondering how long it would take after merely mentioning the name of some hypothetical new AWS-based product before it started appearing in job ads. So he made up a product name, put out a tweet, and waited. It took just three days <https://www.theregister.com/2021/07/05/infinidash/>. I had a look at the linked job ad, and it still contains the sentence “Infinidash is at the core of everything we do”, with absolutely no hint that it might be tongue-in-cheek. This is just a continuation of the long-standing phenomenon among HR departments and employment agencies putting out job ads requiring something like “5+ years experience in Technology X”, when Technology X has only been around for a few months.
