Cryptocurrency mining chrome extension

Hackers are quietly hijacking personal computers, company servers, cable routers, mobile devices and other forms of computing power to stealthily mine cryptocurrencies — a problem that cybersecurity experts warn is growing rapidly. The act, known as cryptojacking, has grown in popularity because it is hard to detect and reasonably passive, unlike other hacks such as Ransomware, which can encrypt files or lock users out of systems until money is paid. The rise in the value of bitcoin and other cryptocurrencies in recent years has made cryptocurrency mining a lucrative activity. Cryptocurrency mining uses computing power to compete against other computers to solve complex math problems, with that effort rewarded with bits of cryptocurrencies.

Chrome webstore to remove cryptocurrency mining extensions


Google's automatic verification system for Chrome extension uploads to the official Chrome Web Store is a wreck; less than a day after the Steam Inventory Helper incident , another Chrome extension was found to abuse user trust by using user systems for crypto currency mining.

The most recent version of Steam Inventory Helper transfers any page a user visits in Chrome to a third-party server. The free browser extension SafeBrowse on the other hand runs a crypto mining module in the background while it is enabled in the browser and while the browser is open on the system.

SafeBrowse's main purpose is to skip forced intermediary advertising pages from services such as adf. The most recent update of the browser extension includes a crypto miner that runs in the browser automatically.

It uses the computer's processing power -- CPU -- to mine cryptocurrency. Chrome users who have installed the browser extension may have noticed that CPU usage is going up whenever Chrome is open. Those with proper firewall protection may have noticed that connections are made to the domain coin-hive. A quick look at the source code of the Chrome extension SafeBrowse confirms that connections are made to the site. The rise of in-browser crypto mining seems inevitable.

Torrentfreak broke the story, and a quick analysis of the Pirate Bay's code revealed that it too used the JavaScript miner provided by Coin Hive.

Now it is the first Google Chrome extension that mines crypto currency while the extension is installed, and it seems likely that it won't be the only one that will make use of such an option. While there is nothing wrong with crypto mining in the browser, other than that it is highly ineffective as it relies solely on the processor, it becomes a huge issue if the mining is not user initiated but enforced automatically either on visit or when an extension is installed.

The first anti-mining browser extension was released recently. No Coin is designed to block known mining domains, but it may not work properly if the mining comes from an extension and not from a website. Anyway, if you have installed SafeBrowse for Chrome, it is probably a good idea to uninstall the browser extension at this point in time. Google needs to change its stance on the store's verification process for new extensions and extension updates.

Mozilla, a much smaller organization, does this a lot better as it has a manual review policy in place for all new and updated Firefox extensions. You can claim your browser is secure as shit, sandboxed and whatever, but it is all meaningless with such a crazy add-on ecosystem. Not touching Chrome with a ten feet pole.

Now I wonder, are Chromium-based browsers affected by this kind of things? Opera, Vivaldi, Chromium itself, Brave, …. Well, this extension should work on Chromium and Opera, definitely, if you install it from Chrome Store.

I also know that Opera has more stringent requirements around various bits and pieces, from my past correspondence with several extension devs. Mozilla says they manually review the code of submissions to their extension store. Do they manually review each update as well? I ask because there have been examples of a widely used trustworthy extensions that have been secretly bought out, sometimes requiring the original owner to sign a non-disclosure agreement- and then been monetized into what one might consider malware.

However, if Mozilla were to manually review every update Which they may already be doing - that would be a huge security edge. Ideally, there would be both manual and automated checks. Reading that Firefox might be more secure than Chrome is an interesting sort of positive reversion to their original reputation. One of the reasons they took off and became the leading web browser at the beginning of the century was because they were considered much more secure relative to Internet Explorer.

Later, they were considered very insecure relative to other browsers- one year a big convention that buys new computers and installs all updates and updated web browsers, and gives the computers themselves out as a reward to the first person who can hack into them and gain admin level access to the operating system All legal because the owner of the computers gives permission actually stopped using Mozilla Firefox because it was considered too easy to hack relative to all the other major browsers.

They added it back to the contest the next year, but questions kind of remained. Internet is becoming a uninhabitable place, I have no doubt that soon a lot of sites will start to use coin miners. Yea my energy level to keep up with this kind of crap is in the red. We have to fight everyone these days to keep control of our own computers.

But before that, a malicious legacy extension could have crippled uBlock Origin anyway. These rights were removed and NoScript goes through manual reviews like everyone else ever since. The author apologized and acknowledged this conflict went too far. They are now approved automatically. One of the reasons of dropping legacy addons was lack of manpower to review them. They still do occur. No surprises here. These kinds of Crypto miners slipped in are becoming much more common lately and this google fiasco has always happened, its just coming to light more so now that more popular extensions are jumping ship.

Have you noticed this? Yes, I have. As far as I can remember, this seems to be a new behaviour, and comments could be posted in the past with No Script active and just the Ghacks. I mention this because it has been reviewed by Ghacks. I was unable to find the reputation database used by Avast, or the reason why this add-on is flagged in this manner.

It stays there for the time being. Does anyone know if this a false positive or based on actual information? Martin, Did you already notice that your hyperlink reference under the word SafeBrowse does only lead to a Error Nof foud!!!

What happened to the new ghacks theme? The PirateBay tested.. But again it was a test, mining instead of ads are pretty much okay, as long it shutdown after you close the page. Actually mining instead of getting ads is way more secure than getting connected to unknown and possible insecure advertising hosts. This is how you permanently and simply block coin-hive;.

Similarly for Google and Facebook. Malware can infiltrate through many ways, eg email attachments, downloaded files, corrupted ad scripts, OS and program vulnerabilities, etc. I see this as a big step forward compared to ads. There is no harm in using CPU cycles at all, except that it costs for a short amount of time a little bit more energy. Ads can do much more harm here, which was several times now proven by ghacks and other pages.

TPB just need adjustments, but that is what the test was designed for, get feedback and change things. Maybe Ghacks also get such a feature. Notice that it is mostly seedy websites and extensions that are beginning to use crypto-currency mining hiddenware or coinware, eg Pirate Bay.

Those who control bot-nets can also make money by sending millions of spam emails for seedy advertisers, eg ads for Viagra pills, penis elongation pills, dating websites, contacts for love scams, etc. Pirate Bay is a seedy or disreputable website. It has previously been shutdown by certain governments.

I am sure we here constantly tweak our browsers and systems to consume as little memory and resources as possible so having this shady kinda cloak and dagger action happening in the background is not good at all. Its great the umatrix blocks it but I am sure there will be a wack-a-mole situation here too with perhaps more invasive techniques and results. Like reading a book then a commercial appears in the middle of a page. Google has to do something about this.

More and more extensions are now using mining libs. It is disgusting. One of my extensions I used for years now has it too, and I was wondering why I had high CPU all the time since weeks. Save my name, email, and website in this browser for the next time I comment.

Chrome says goodbye to cryptocurrency mining extensions

Enter To Win Here! Ah, cryptocurrency.

Google to purge cryptomining extensions from Chrome Web Store

The number of malicious extensions is rapidly increased over the past few months, especially those related to mining activities. The company has introduced a new Web Store policy that bans any Chrome extension submitted to the Web Store that mines cryptocurrency. Until now, Google only allowed those cryptocurrency mining extensions that explicitly informed users about their mining activities. Google pointed out that the ban on cryptocurrency mining extensions will not affect blockchain-related extensions such as Bitcoin price checkers and cryptocurrency wallet managers. Extensions with blockchain-related purposes other than mining will continue to be permitted in the Web Store. Google ban is another step to protect its users from hidden risks, it follows the recent announcement to ban advertisements related to cryptocurrency. Google is not the unique media firm that imposed a ban on cryptocurrency-related abuses, Twitter recently announced the ban for cryptocurrency-related ads on its platform, in January, Facebook banned all ads promoting cryptocurrency-related initiatives, including Bitcoin and ICOs.

As a result, no new mining extensions are accepted into the store in a measure effective as of Monday April 2 nd , while existing ones will be removed in late June. However, Google has found that around nine out of ten extensions that include mining scripts failed to play by the book, prompting the company to introduce the blanket ban. For example, in December, Google booted a Chrome extension that, in addition to its stated purpose, had also roped unsuspecting users into mining digital coins. The extension had amassed more than , installations over the span of several weeks. Meanwhile, extensions with blockchain -related purposes other than mining get off scot-free in the new policy.

Google has followed the lead of Apple by banning crypto-mining apps from its Play Store. An update to the company's developer policy reads: "We don't allow apps that mine crypto-currency on devices. The company had previously banned crypto-currency mining extensions on its Chrome browser. The move marks another step by banks and tech companies get to grips with the practicalities of crypto-currencies.

But that fragile hope has been dashed.

Qualys Malware Research Labs is announcing the release of Qualys BrowserCheck CoinBlocker Chrome extension to detect and block browser-based cryptocurrency mining, aka cryptojacking. Attackers carry out these attacks by infecting popular sites with JavaScript that enables cryptojacking. Because cryptojacking helps attackers earn cryptocurrency without spending a dime on mining infrastructure, it is very profitable. There is a lot of money to be made for attackers leveraging these projects, and cryptomining is gradually moving to the center stage of threat landscape as an even more attractive option compared to the recent favorite ransomware campaigns. Cryptojacking has also gone mainstream recently because it is safer for cyber criminals and webmasters than ransomware, which requires interaction with the victim to collect payment. And because cryptojacking is browser based, it is easier to infect victims than hacking into servers.

There are many websites that use the hardware on your phones and computers to mine cryptocurrency, which in turn could be very harmful for your devices. The worst part here is that there's no easy way to find out which website is harmful and which one is not, since many of them don't inform you that they use your device to mine cryptocurrency. Instead, all it requires is a few lines of code in Javascript that runs in the background while you browse the Web and then you could witness slow speeds on your system, reduced battery life and a significant damage to the overall life of the components. Don't worry though, we have got you covered.
