Bitcoin Gold, the Latest Bitcoin Fork, Explained

Timothy B. Lee via Ars Technica explains Bitcoin Gold: A new cryptocurrency called Bitcoin Gold is now live on the Internet. It aims to correct what its backers see as a serious flaw in the design of the original Bitcoin. There are hundreds of cryptocurrencies on the Internet, and many of them are derived from Bitcoin in one way or another. But Bitcoin Gold — like Bitcoin Cash, another Bitcoin spinoff that was created in August — is different in two important ways. Bitcoin Gold is branding itself as a version of Bitcoin rather than merely new platforms derived from Bitcoin’s source code. It has also chosen to retain Bitcoin’s transaction history, which means that, if you owned bitcoins before the fork, you now own an equal amount of “gold” bitcoins. While Bitcoin Cash was designed to resolve Bitcoin’s capacity crunch with larger blocks, Bitcoin Gold aims to tackle another of Bitcoin’s perceived flaws: the increasing centralization of the mining industry that verifies and secures Bitcoin transactions. The original vision for Bitcoin was that anyone would be able to participate in Bitcoin mining with their personal PCs, earning a bit of extra cash as they helped to support the network. But as Bitcoin became more valuable, people discovered that Bitcoin mining could be done much more efficiently with custom-built application-specific integrated circuits (ASICs). As a result, Bitcoin mining became a specialized and highly concentrated industry. The leading companies in this new industry wield a disproportionate amount of power over the Bitcoin network. Bitcoin Gold aims to dethrone these mining companies by introducing an alternative mining algorithm that’s much less susceptible to ASIC-based optimization. In theory, that will allow ordinary Bitcoin Gold users to earn extra cash with their spare computing cycles, just as people could do in the early days of Bitcoin.

Study Finds SpaceX Investment Saved NASA Hundreds of Millions

schwit1 shares a report from Popular Mechanics: When a SpaceX Dragon spacecraft connected with the International Space Station on May 25, 2012, it made history as the first privately-built spacecraft to reach the ISS. The Dragon was the result of a decision 6 years prior — in 2006, NASA made an “unprecedented” investment in SpaceX technology. A new financial analysis shows that the investment has paid off, and the government found one of the true bargains of the 21st century when it invested in SpaceX. A new research paper by Edgar Zapata, who works at Kennedy Space Center, looks closely at the finances of SpaceX and NASA. “There were indications that commercial space transportation would be a viable option from as far back as the 1980s, ” Zapata writes. “When the first components of the ISS were sent into orbit 1998, NASA was focused on “ambitious, large single stage-to-orbit launchers with large price tags to match.” For future commercial crew missions sending astronauts into space, Zapata estimates that it will cost $405 million for a SpaceX Dragon crew deployment of 4 and $654 million for a Boeing Starliner, which is scheduled for its first flight in 2019. That sounds like a lot, and it is, but Zapata estimates that its only 37 to 39 percent of what it would have cost the government. Read more of this story at Slashdot.

TorMoil Vulnerability Leaks Real IP Address From Tor Browser Users; Security Update Released

Catalin Cimpanu, reporting for BleepingComputer: The Tor Project has released a security update for the Tor Browser on Mac and Linux to fix a vulnerability that leaks users’ real IP addresses. The vulnerability was spotted by Filippo Cavallarin, CEO of We Are Segment, an Italian company specialized in cyber-security and ethical hacking. Cavallarin privately reported the issue — which he codenamed TorMoil — to the Tor Project last week. Tor Project developers worked with the Firefox team (Tor Browser is based on the Firefox browser) to release a fix. Today, the Tor team released version 7.0.9 to address the vulnerability. Tor Browser 7.0.9 is only available for Mac and Linux users. Tor Browser on Windows is not affected. Read more of this story at Slashdot.

Android Oreo Bug Sends Thousands of Phones Into Infinite Boot Loops

An anonymous reader writes: A bug in the new “Adaptive Icons” feature introduced in Android Oreo has sent thousands of phones into infinite boot loops, forcing some users to reset their devices to factory settings, causing users to lose data along the way. The bug was discovered by Jcbsera, the developer of the Swipe for Facebook Android app (energy-efficient Facebook wrapper app), and does not affect Android Oreo (8.0) in its default state. The bug occurs only with apps that use adaptive icons — a new feature introduced in Android Oreo that allows icons to change shape and size based on the device they’re viewed on, or the type of launcher the user is using on his Android device. For example, adaptive icons will appear in square, rounded, or circle containers depending on the theme or launcher the user is using. The style of adaptive icons is defined a local XML file. The bug first manifested itself when the developer of the Swipe for Facebook Android app accidentally renamed the foreground image of his adaptive icon with the same name as this XML file (ic_launcher_main.png and ic_launcher_main.xml). This naming scheme sends Android Oreo in an infinite loop that regularly crashes the device. At one point, Android detects something is wrong and prompts the user to reset the device to factory settings. Users don’t have to open an app, and the crashes still happen just by having an app with malformed adaptive icons artifacts on your phone. Google said it will fix the issue in Android Oreo 8.1.

Samsung Made a Bitcoin Mining Rig Out of 40 Old Galaxy S5s

An anonymous reader quotes a report from Motherboard: Samsung is starting a new “Upcycling” initiative that is designed to turn old smartphones and turn them into something brand new. Behold, for example, this bitcoin mining rig, made out of 40 old Galaxy S5 devices, which runs on a new operating system Samsung has developed for its upcycling initiative. Samsung premiered this rig, and a bunch of other cool uses for old phones, at its recent developer’s conference in San Francisco. Upcycling involves repurposing old devices instead of breaking them down for parts of reselling them. The people at Samsung’s C-Lab — an engineering team dedicated to creative projects — showed off old Galaxy phones and assorted tablets stripped of Android software and repurposed into a variety of different objects. The team hooked 40 old Galaxy S5’s together to make a bitcoin mining rig, repurposed an old Galaxy tablet into a ubuntu-powered laptop, used a Galaxy S3 to monitor a fishtank, and programed an old phone with facial recognition software to guard the entrance of a house in the form of an owl. Samsung declined to answer specific questions about the bitcoin mining rig, but an information sheet at the developer’s conference noted that eight galaxy S5 devices can mine at a greater power efficiency than a standard desktop computer (not that too many people are mining bitcoin on their desktops these days).

Critical Flaws In Maritime Communications System Could Endanger Entire Ships

Orome1 shares a report from Help Net Security: IOActive security consultant Mario Ballano has discovered two critical cybersecurity vulnerabilities affecting Stratos Global’s AmosConnect communication shipboard platform. The platform works in conjunction with the ships’ satellite equipment, and integrates vessel and shore-based office applications, as well as provides services like Internet access for the crew, email, IM, position reporting, etc. The first vulnerability is a blind SQL injection in a login form. Attackers that successfully exploit it can retrieve credentials to log into the service and access sensitive information stored in it. The second one is a built-in backdoor account with full system privileges. “Among other things, this vulnerability allows attackers to execute commands with SYSTEM privileges on the remote system by abusing AmosConnect Task Manager, ” Bellano shared. The found flaws can be exploited only by an attacker that has access to the ship’s IT systems network, he noted, but on some ships the various networks might not be segmented, or AmosConnect might be exposed to one or more of them. The vulnerabilities were found in AmosConnect 8.4.0, and Stratos Global was notified a year ago. But Inmarsat won’t fix them, and has discontinued the 8.0 version of the platform in June 2017.

Saudi Arabia Becomes First Nation To Grant Citizenship To Humanoid Robot

Saudi Arabia became the first country in the world to offer citizenship to a humanoid robot, but Brad Keywell, CEO of Uptake, a predictive analytics technology company, told FOX Business on Thursday artificial intelligence (AI) will not replace humans anytime soon. From a report: “Humans are made super-human through the intelligence that can be derived from these sensors and there is a clear argument that’s made about the possibility that there will be no humans, there’d be just autonomous everything… but this is something that has historically involved humans and I just don’t see that changing, ” he told Maria Bartiromo on “Mornings with Maria.” Uptake’s products are used in a collection of industries ranging from energy to aviation, helping “people and machines work better and faster, ” according to the company website.

2 Million IoT Devices Enslaved By Fast-Growing BotNet

An anonymous reader writes: Since mid-September, a new IoT botnet has grown to massive proportions. Codenamed IoT_reaper, researchers estimate its current size at nearly two million infected devices. According to researchers, the botnet is mainly made up of IP-based security cameras, routers, network-attached storage (NAS) devices, network video recorders (NVRs), and digital video recorders (DVRs), primarily from vendors such as Netgear, D-Link, Linksys, GoAhead, JAWS, Vacron, AVTECH, MicroTik, TP-Link, and Synology. The botnet reuses some Mirai source code, but it’s unique in its own right. Unlike Mirai, which relied on scanning for devices with weak or default passwords, this botnet was put together using exploits for unpatched vulnerabilities. The botnet’s author is still struggling to control his botnet, as researchers spotted over two million infected devices sitting in the botnet’s C&C servers’ queue, waiting to be processed. As of now, the botnet has not been used in live DDoS attacks, but the capability is in there. Today is the one-year anniversary of the Dyn DDoS attack, the article points out, adding that “This week both the FBI and Europol warned about the dangers of leaving Internet of Things devices exposed online.” Read more of this story at Slashdot.
