Javascript Miner As A Source Of Traffic Revenue For Websites?

Javascript Miner As A Source Of Traffic Revenue For Websites?

Javascript miner as a source of traffic revenue for websites? I've come across this article: To summarise for the lazy ones, piratebay has done a 24 hour trial, where they CPU mined Monero with a javascript app executed automatically on website visitors What do you think, could it be that such js mining apps will one day take over as the main way of monetising website traffic (opposed to adverts) I read this earlier as well. Was surprised TPB dropped it in without any announcements but guess it was a trial and not on all pages. You'd be able to stop it relatively easy by blocking the javascript so not sure how mainstream it will go ... Plus not all common internet sites will care for crypto in its current state so can only see sites like TPB being interested in it. I don't see a problem with people doing this as long as a few things are true. 1. The sites tell you that they are mining with your CPU. 2. The sites limit it to a small % of the CPU. 3. Normal ad blockers block it from mining. 4. Don't jam your site with ads AND try to slip in a miner. With that being said, I do not think mining will outperform normal ad revenue in a direct comparison. Even if a site gets alot of daily hits, the majority of users aren't going to be leaving the browser on that site for a long period of time.

The Pirate Bay Is Secretly Running A Bitcoin Miner In The Background, Increasing Your Cpu Usage

The Pirate Bay Is Secretly Running A Bitcoin Miner In The Background, Increasing Your Cpu Usage

The Pirate Bay is secretly running a Bitcoin miner in the background, increasing your CPU usage When it comes to the Pirate Bay, it's usually movie studios, music producers and software creators that get annoyed with the site -- you know, copyright and all that. But in an interesting twist it is now users who find themselves irked by -- and disappointed in -- the most famous torrent site in the world. So what's happened? Out of the blue, the Pirate Bay has added a Javascript-powered Bitcoin miner to the site. Nestling in the code of the site is an embedded cryptocurrency miner from Coinhive. Users who have noticed an increase in resource usage on their computers as a result of this are not happy. The issue is a very new one, with users only noticing a CPU spike starting later on in the day yesterday. Needless to say, the reaction has not been good -- even from the Pirate Bay's own moderators. Over on Reddit , there are complaints about "100% CPU on all 8 threads while visiting TPB," and there are also threads on the PirateBay Forum . As noted by TorrentFreak , a quick delve into the HTML of the PirateBay reveals what's going on. An administrator and "supermod" on the PirateBay Forum, Sid is far from impressed: ffs [That's addressed to Winston not you lot.] That really is serious, so hopefully we can get some action on it quickly. And perhaps get some attention for the uploading and commenting bugs while they're at it. He offers the following advice for anyone concerned about the latest addition: Until it is fixed (and I would expect it to be fixed sooner rather than later) noscript will block it from running, as will disabling javascript. Blocking/disabling javascript will compromise site functionality in several ways: - scrolling back though pages of comments won't wo Continue reading >>

Cbs's Showtime Caught Mining Crypto-coins In Viewers' Web Browsers

Cbs's Showtime Caught Mining Crypto-coins In Viewers' Web Browsers

The websites of US telly giant CBS's Showtime contained JavaScript that secretly commandeered viewers' web browsers over the weekend to mine cryptocurrency. The flagship Showtime.com and its instant-access ShowtimeAnytime.com sibling silently pulled in code that caused browsers to blow spare processor time calculating new Monero coins a privacy-focused alternative to the ever-popular Bitcoin. The hidden software typically consumed as much as 60 per cent of CPU capacity on computers visiting the sites. The scripts were written by Code Hive, a legit outfit that provides JavaScript to website owners: webmasters add the code to their pages so that they can earn slivers of cash from each visitor as an alternative to serving adverts to generate revenue. Over time, money mined by the Code-Hive-hosted scripts adds up and is transferred from Coin Hive to the site's administrators. One Monero coin, 1 XMR, is worth about $92 right now. However, it's extremely unlikely that a large corporation like CBS would smuggle such a piece of mining code onto its dot-coms especially since it charges subscribers to watch the hit TV shows online suggesting someone hacked the websites' source code to insert the mining JavaScript and make a quick buck. The JavaScript, which appeared on the sites at the start of the weekend and vanished by Monday, sits between HTML comment tags that appear to be an insert from web analytics biz New Relic. Again, it is unlikely that an analytics company would deliberately stash coin-mining scripts onto its customers' pages, so the code must have come from another source or was injected by miscreants who had compromised Showtime's systems. Here's a screenshot of the code on showtime.com, seen by El Reg before it was removed. The mining script was loaded early on th Continue reading >>

The Pirate Bay Resumes Running In-browser Javascript Cryptocurrency Miners

The Pirate Bay Resumes Running In-browser Javascript Cryptocurrency Miners

The Pirate Bay Resumes Running In-Browser Javascript Cryptocurrency Miners The major torrenting website, The Pirate Bay, is reported to again be using cryptocurrency mining scripts on its website. Last month, it was discovered that The Pirate Bay had embedded multiple Monero miners on its website, which the company claimed was being trialed as an alternative revenue model to hosting ads. Also Read: Pirate Bay Founders Njalla Offers Anonymous Domain Registration for Bitcoin The Pirate Bay Are Continuing to Host Ads Despite the Miner It has been revealed that The Pirate Bay has again employed a javascript cryptocurrency miner, Coinhive, on its website. The script hijacks computing power from the websites visitors and diverts such to mining Monero which is then sent to a wallet owned by The Pirate Bay. Last month, the discovery of cryptocurrency mining scripts on The Pirate Bays website generated an uproar from many of their users. The company hastily abandoned the scripts, claiming that such comprised a short experiment with an alternative revenue model that would allow the website to abandon advertising as its primary source of income. The company stated as you may have noticed we are testing a Monero javascript miner. This is only a test. We really want to get rid of all the ads. But we also need enough money to keep the site running Let us know what you think in the comments. Do you want ads or do you want to give away a few of your CPU cycles every time you visit the site? Of course the mining can be blocked by a normal ad-blocker. Javascript Cryptocurrency Miners Are Gaining Popularity Torrentfreak has reported that the Monero miner is not directly embedded in the sites core code but runs through an ad script. As such, the website has conceded that it is possible th Continue reading >>

Javascript Bitcoin Miner | Hacker News

Javascript Bitcoin Miner | Hacker News

It is bad to use a bunch of the user's CPU without any notice. They will probably notice that your site makes their computer slow and never come back again. Also, once they find out you've been using their CPU power/electricity/battery life surreptitiously for private, unshared gain, you will probably have some angry customers. Additionally, does this automatically hook in to slush's pool or something? Bitcoin mining is practically useless on CPU; even the fastest CPUs out get way, way less than 10mhash. The average length of time to find a block at 9999khash and current difficulty is 1200+ days, so even that estimate is over-optimistic, so this isn't worth anything if your users don't sit on your site for 5 years+, unless it's hooked into a pool or some other contraption to pay on shares instead of blocks. Chrome13-canary: ~15.2k/s FF4: ~6.4k/s Safari5: ~6.2k/s IE9: ~1.6k/s So yeah, massively massively slower than regular GPU mining. Anyone know of a way to push WebGL into doing hashing functions, and reading the results out? And you come to a total of 21,600,000 unique visitors per day that you would need to your website in order to hash the equivalent of a $100 GPU. Or make about $8 per day according to the bitcoin calculator right now from 21 million unique visitors.... totally not worth it. So, yeah. Significantly crapping on the user experience of 21M people by reducing their battery life, adding heat, adding fan noise, slowing down other actions - all to substitute for one gpu? It seems like there must be better ways to ruin your high traffic websites reputation if that's what you're looking to do. And if that's all IE9 does, how about the 40-60% of visitors using earlier IE versions with even worse JS performance (and no WebGL, of course). This doesn't seem par Continue reading >>

Browser-based Cryptocurrency Mining Makes Unexpected Return From The Dead

Browser-based Cryptocurrency Mining Makes Unexpected Return From The Dead

Browser-Based Cryptocurrency Mining Makes Unexpected Return from the Dead Once thought of as dead, browser-based cryptocurrency mining makes an unlikely return, coming back to haunt websites and their visitors. Browser-based cryptocurrency mining activity exploded in the last few months of 2017. After many years of deathly silence, the catalyst appears to be the launch of a new browser-based mining service in September by Coinhive. This service wraps everything up nicely in an easy-to-use package for website owners and has injected new life into an idea that was long thought of as dead and buried. Browser-based cryptocurrency mining is not new;it's been around since at least 2011. A surge in the cryptocurrency market in 2017, as well as availability of coins that are mineable using home hardware and easy-to-use JavaScript APIs, has led to a torrent of malicious browser-based mining affecting many well-known and lesser-known websites. Mobile devices have not been spared from cryptocurrency mining, as witnessed by a 34 percent increase in the number of mobile apps incorporating cryptocurrency mining code. Browser-based mining, as its name suggests, is a method of cryptocurrency mining that happens inside a browser and is implemented using scripting language. This is different compared to the more widely known file-based cryptocurrency mining approach which involves downloading and running a dedicated executable file. Browser-based mining dates back to May of 2011 when an innovative service called BitcoinPlus.com was initially launched back when Bitcoin was cheap and mining was easynot to be confused with another cryptocurrency known as Bitcoin Plus.org (XBC). That service was in many ways remarkably similar to its modern reincarnation, Coinhive. It used JavaScript code f Continue reading >>

The Pirate Bay Website Runs A Cryptocurrency Miner (updated)

The Pirate Bay Website Runs A Cryptocurrency Miner (updated)

The Pirate Bay Website Runs a Cryptocurrency Miner (Updated) A few hours ago a cryptocurrency miner appeared on The Pirate Bay website, using the computer resources of visitors to mine Monero coins. The operators of The Pirate Bay are testing it as a new way to generate revenue, but many users aren't happy. Four years ago many popular torrent sites added an option to donate via Bitcoin. The Pirate Bay was one of the first to jump on board and still lists its address on the website. While theres nothing wrong with using Bitcoin as a donation tool, adding a Javascript cryptocurrency miner to a site is of a totally different order. A few hours ago many Pirate Bay users began noticing that their CPU usage increased dramatically when they browsed certain Pirate Bay pages. Upon closer inspection, this spike appears to have been caused by a Bitcoin miner embedded on the site. The code in question is tucked away in the sites footer and uses a miner provided by Coinhive . This service offers site owners the option to convert the CPU power of users into Monero coins. The miner does indeed appear to increase CPU usage quite a bit. It is throttled at different rates (weve seen both 0.6 and 0.8) but the increase in resources is immediately noticeable. The miner is not enabled site-wide. When we checked, it appeared in the search results and category listings, but not on the homepage or individual torrent pages. There has been no official comment from the site operators on the issue (update, see below), but many users have complained about it. In the official site forums, TPB supermoderator Sid is clearly not in agreement with the sites latest addition. That really is serious, so hopefully we can get some action on it quickly. And perhaps get some attention for the uploading and com Continue reading >>

Javascript Miner - Crypto Mining Blog

All About BTC, LTC, ETH mining as well as other alternative crypto currencies Grid Cash, Another Website Mining Service for Webmasters CoinHive may stull be the most popular and misused service for website owners willing to monetize their website traffic with visitors mining crypto, but it is not the only one. In fact there are others that are trying to implement the website mining in a less obtrusive way, giving webmasters more control and warning visitors and letting them stop mining. One such service that we have recently checked out is Grid Cash that uses a web-based Monero (XMR) miner. The service allows webmasters to fully customize the way the miner works, including control over the CPU load (resources used), so by lowering the usage you can easily make the miner less of a burden for the users. There are options to load the mining code locally, so it will not be easily blocked like when it is being loaded from a single remote host and of course the option to enable notification for users with an opt out feature. There is a detailed statistics available that helps you keep track of your earnings, though they depend a lot on how many visitors you get and for how long they stay on your website. We advise you not to try to abuse services like this one that uses your website visitors resources to mine for you as youd most likely want to keep the visitors and increase them instead of driving them away, so proceed with caution when using services like these. CoinHive, a Monero (XMR) Crypto Miner for Your Website Recently we have introduced to you JSEcoin JavaScript Embeded Cryptocurrency for Webmasters as an interesting new project that uses JavaScript mining via the browser of users and that can be used to monetize website traffic. But another similar service has gott Continue reading >>

Javascript - Site With A Bitcoin Miner Script - Stack Overflow

Javascript - Site With A Bitcoin Miner Script - Stack Overflow

I found some of my users visiting a site that seemed to have a Bitcoin mining JS script in its code: var miner = new CoinHive.Anonymous('3858f62230ac3c915f300c664312c63f');miner.start(); My question is, with this are the users still infected even if they navigate away from the page? Do these sort of programs only work while the user has the page open in the browser? No, and Yes, respectively. Dai Sep 28 '17 at 19:31 Learn about Service Workers, which give some level of persistence (and can be abused to give more) SLaks Sep 28 '17 at 19:33 Thanks @SLaks, I checked the page and the js script and can see its not using Service Workers. Its good to know about them though for future. user92592 Sep 28 '17 at 19:40 It uses them. Check my answer. Artem Arkhipov Sep 28 '17 at 20:08 @ArtemArkhipov: You're confusing Web Workers and Service Workers. SLaks Sep 28 '17 at 22:02 with this are the users still infected even if they navigate away from the page? Do these sort of programs only work while the user has the page open in the browser? Yes, the script will only run on the website that includes it, while the page is open in the browser More information about this script: Coinhive offers a JavaScript miner for the Monero Blockchain (...) that you can embed in your website. Your users run the miner directly in their Browser Coinhive does not appear to be "malware" since it does not appear to do anything particularly harmful to the user's computer. If that is the case, the users computers were never "infected" with anything. It is extremely common these days for websites to load tons of third party scripts and cookies in the background and do hundreds of things you are not aware of every time you use the internet. Most sites load a Google Analytics tracking script when you visit them Continue reading >>

New Javascript Monero Miner Released As More Sites Begin To Mine Coins

New Javascript Monero Miner Released As More Sites Begin To Mine Coins

Home Featured New JavaScript Monero Miner Released as More Sites Begin to Mine Coins New JavaScript Monero Miner Released as More Sites Begin to Mine Coins Posted by: DividedBy0 October 23, 2017in Featured , News Updates Leave a comment A new JavaScript Monero miner project called Crypto-Loot was launched recently. This new JavaScript Monero miner is a competitor to Coinhive , a mining service which originated from a German image board. These cryptocurrency miners run inside of web browsers when a user navigates to a page which loads and runs the mining script. Some websites have deployed these Monero miners in a hidden or secretive way, which has led some people to claim these services are nothing more than malware. These new JavaScript cryptocurrency miners build on an idea which first appeared around two and a half years after the debut of Bitcoin, the first true decentralized cryptocurrency. In the summer of 2011 a mining pool site called bitp.it was launched. Bitp.it allowed users to embed a JavaScript miner into websites and would mine Bitcoin using the computer processing power of that sites visitors. The software behind bitp.it was released as jsMiner. Bitp.it would go on to shut down at the end of 2011 and the site administrators made off with all of their users Bitcoin. Other JavaScript Bitcoin miners were created, and some are even still maintained to this day, such as Hash Me If You Can. However, the ability to mine Bitcoin using standard CPUs and GPUs is no longer practical. New JavaScript miners like Coinhive and Crypto-Loot mine for Monero instead of Bitcoin. Monero is one of the most privacy-centric cryptocurrencies available on the market today, and its coins can be mined efficiently with both regular CPUs and GPUs, instead of specialized processors li Continue reading >>

Coinhive Review: Embeddable Javascript Crypto Miner - 3 Daysin

Coinhive Review: Embeddable Javascript Crypto Miner - 3 Daysin

Coinhive review: Embeddable JavaScript Crypto Miner - 3 daysin I discovered Coinhive 3 days ago on HN, and decided to give it a try on one of my smaller websites, as an experiment. For those who dont know what Coinhive is, this is their intro on their website : Coinhive offers a JavaScript miner for the Monero Blockchain ( Why Monero? ) that you can embed in your website. Your users run the miner directly in their Browser and mine XMR for you in turn for an ad-free experience, in-game currency or whatever incentives you can come up with. Basically your visitors/users mine crypto-currencies (Monero here) with their CPU for you in exchange for the content you are providing, its a possible alternatives to ads, and a better monetization option in my opinion I tried it on a website with approx 1k visits a day, with a 0:55 seconds session duration average last month. The objective was to replace the non-intrusive ads Im currently displaying. It seems that Im am constantly between 150450 Hashes/s, which is pretty low. It seems logical: the website having at any minute between 5 and 15 visitors, thats an average of 2025 Hashes/s per user So I made 0.00947 XMR in 60 hours, a whopping $0.89, thats $0.36 a day For this exact website, its 4 to 5 times less than what it makes with non-intrusive ads (banner + text only) As stated on Coinhive, the embedded JS miner is well suited for websites with longer sessions duration average . This website isnt probably a good use case for Coinhives embedded JS miner, but from the small sample data I have, its not a viable alternative to ads Hope this helps if you were curious about remplacing ads with Coinhives Embeddable JavaScript Crypto Miner!

Cpu Mining - How Useful Is A Javascript Miner? - Bitcoin Stack Exchange

Cpu Mining - How Useful Is A Javascript Miner? - Bitcoin Stack Exchange

I don't have a great understanding of how bitcoin mining works, but how useful would a JavaScript miner be for collecting revenue from visitors? Stupid question, but if I put the user in as part of a mining pool, must their computer actually find a hash in order for me to make revenue? Is this at all practical? You will have to explain to the revenue service why you make this income in bitcoins. Using the website visitors' electrical energy for mining bitcoins could be seen as theft. user3284699 Jan 27 '16 at 19:38 Javascript has access to OpenGL ES, including shaders, so it has access to programmable parts of the GPU at nearly native speeds. I think that a smart kid might be able to build a fragment shader that does SHA256 hashing, which outputs to the stencil buffer, so that Javascript has a 2-way communication channel with the GPU. So yeah, you could probably use javascript to mine at really nice speeds. Maybe 70% or 80% of what an OpenCL GPU miner does? Is it actually working for you? Because in chrome it shuts down the tab. Salvador Dali Apr 27 '13 at 22:43 It's the fact that it once did work that counts, as it proves it can be done again. Tom van der Woerdt Apr 27 '13 at 23:11 @SalvadorDali Ensure you have Hardware Acceleration enabled. Take a look here webupd8.org/2014/01/enable-hardware-acceleration-in-chrome.html erm3nda Jan 4 '16 at 2:57 In the header you should put (For consideration), "You are now mining Cyptocurrency for funding the website and the owner.

A Bitcoin miner implemented in JavaScript and running on GAE If nothing happens, download GitHub Desktop and try again. If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. This is a Bitcoin Miner implemented in JavaScript.Originally by progranism , improved by kr105rlz and cmaclell , here modified by me to work on GAE . It is intended for usein a Bitcoin Mining Pool , butits main purpose is to act as a learning tool and micro web miner. Feel free to browse the commented source-codeand learn more about how Bitcoins are mined. Download the full source code. You need a Google App Engine application defined and ready for code to be uploaded.Modify the app.yaml according to your application name, rename or copy config.py.sample to config.py and modify it to use your pool credentials. Open the "ninja" w.html page in your app path and you're off to mine! Yes, though it isn't very good at mining! It operates much slowerthan even a standard CPU miner, and so it is unlikely to generate much income. However it can be loaded on a website so your visitors can calculate bitcoins for you. Please read, this miner doesn't implement any real long-polling or caching techniques to minimize unnecessary connections to the pool server.Instead, it polls every hour the pool server you configured and "replaces" any work holder than an hour with the received one.It could well overwrite the same work but 1 connection every hour shouln't disturb too much. Indeed, clients could be working on already solved work.It is recommended to use it only on local, personal installations before connecting to big (or even small) pools. Continue reading >>

Cryptocurrency Mining Scripts Now Run Even After You Close Your Browser

Cryptocurrency Mining Scripts Now Run Even After You Close Your Browser

Cryptocurrency Mining Scripts Now Run Even After You Close Your Browser Wednesday, November 29, 2017 Swati Khandelwal Some websites have found using a simple yet effective technique to keep their cryptocurrency mining javascript secretly running in the background even when you close your web browser. Due to the recent surge in cryptocurrency prices, hackers and even legitimate website administrators are increasingly using JavaScript-based cryptocurrency miners to monetize by levying the CPU power of their visitor's PC to mine Bitcoin or other cryptocurrencies. After the world's most popular torrent download website, The Pirate Bay, caught secretly using Coinhive , a browser-based cryptocurrency miner service, on its site last month, thousands of other websites also started using the service as an alternative monetization model to banner ads. However, websites using such crypto-miner services can mine cryptocurrencies as long as you're on their site. Once you close the browser window, they lost access to your processor and associated resources, which eventually stops mining. Unfortunately, this is not the case anymore. Security researchers from anti-malware provider Malwarebytes have found that some websites have discovered a clever trick to keep their cryptocurrency mining software running in the background even when you have closed the offending browser window. According to a blog post published Wednesday morning by Malwarebytes, the new technique works by opening a hidden pop-under browser window that fits behind the taskbar and hides behind the clock on your Microsoft's Windows computer. From there (hidden from your view), the website runs the crypto-miner code that indefinitely generates cryptocurrency for the person controlling the site while eating up CPU cycles Continue reading >>

How To Become A Bitcoin Miner In 10 Seconds Or Less

How To Become A Bitcoin Miner In 10 Seconds Or Less

Become a Bitcoin Miner in 10 seconds or less Become a Bitcoin Miner in 10 seconds or less!This Javascript-based bitcoin miner performs the exact same hashing work on your computer as is performed on the highest-end GPUs used by Bitcoins nuttiest miners. The mining site will show you the amount of work (measured as a number of hashes per second) that the javascript miner can perform running inside your browser. For comparison, as of the most-recent difficulty adjustment, the total amount of hashing performed on the Bitcoin network globally is about 3.1 Thash/s. That T stands for the SI prefix tera meaning trillion. Thus the entire Bitcoin network is performing hashing work at the rate of 3,100,000,000,000 hashes per second. Chrome will generally be the browser software that will return the highest hash/s number for most computer systems. A top of the line $2,200+ mining rig with dual AMD Radeon 6990s and running the latest builds of specialized miner software will hash at approximately 1.44 Ghash/s (1,4400,000,000 hashes/s) andearnjust under $30 USD per day at the present difficulty level and market exchange rate. In other words, the Javascript miner running on the lone PC wont yield anyone much money. However, this javascript miner code may be added to any website such that mining is performed by any visitors to the site. There are plenty of reasons that is not a good idea yet in some instances using the miner code in this manner is entirely acceptable. But go ahead. Give it a try. Mining for bitcoins will be one more thing you can draw a line through on your bucket list. Continue reading >>
