Investment in crypto-assets is unregulated, may not be suitable for retail investors and the entire amount invested may be lost. It is important to read and understand the risks of this investment, which are explained in detail here.

Cryptojacking is a relatively new threat on the Internet. It refers to websites abusing computing resources of visitors to mine cryptocurrency.

Internet users notice that something is wrong when the computer they use slows down to a crawl suddenly and when fans speed up in an attempt to cool down components of the device that get hammered.

The main issue with cryptojacking is that it is done behind the backs of users. Sites load cryptomining scripts on load to mine cryptocurrency using the resources of the computer of the user visiting the site. There is no opt-in process or information on what is going on.

Sites run these scripts to generate revenue. One of the advantages of running mining operations in the browser is that it happens in the background. It does not interfere with the site's layout or content.

Browser extensions may load crypto mining scripts as well. These work in the background just like scripts loaded by sites.

Cryptojacking Test

Opera Software was the first browser-making company that implemented anti-crypto mining protections in the browser natively.

While Opera was the first browser, content-blocking lists added cryptomining scripts before Opera did so.

Opera Software engineers created a site that you may visit to test whether you are protected against cryptojacking.

Visit the website and click on the start button on it to run the test. It won't take longer than a couple of seconds to complete and the result is either that the browser that you are using is protected or unprotected.

Opera Software displays aggregate ratings on the site as well. 73.6% of all users are protected from cryptojackingat the time of writing according to the statistics on the page.

Users who run browsers that are not protected have several options at their disposal to protect their browsers against crypto mining attacks.

  1. Use a browser extension that protects against JavaScript mining scripts.
  2. Use the Opera browser with ad-blocking enabled.
  3. Use a security software that protects against mining scripts.
  4. Install an anti-mining browser extension.
  5. Disable JavaScript on untrusted sites.

Closing Words

Opera tests the protection against a Coin Hive script only which leaves the possibility that the browser is vulnerable to these scripts. It is only a matter of time usually before new scripts or URLs do get blocked though.

Now You: Did you run into cryptomining sites in the past?

      Well it is a bit difficulty to distinguish between name.com domains and files for instance.

    The comments section under this very article (3 comments) is identical to the comments section found under the following article:
    https://www.ghacks.net/2023/08/15/netflix-is-testing-game-streaming-on-tvs-and-computers/

    Not sure what the issue is, but have seen this issue under some other articles recently but did not report it back then.

    With the cloud, there is no such thing as unlimited storage or privacy. Stop relying on these tech scums. Purchase your own hardware and develop your own solutions.

      This is a certified reddit cringe moment. Hilarious how the article’s author tries to dress it up like it’s anything more than a png for doing the reddit corporation’s moderation work for free (or for bribes from companies and political groups)

    With Google Chrome, it’s only been 1,500 for some time now.

    Anyone who wants to force me in such a way into buying something that I can get elsewhere for free will certainly never see a single dime from my side. I don’t even know how stupid their marketing department is to impose these limits on users instead of offering a valuable product to the paying faction. But they don’t. Even if you pay, you get something that is also available for free elsewhere.

    The algorithm has also become less and less savvy in terms of e.g. English/German translations. It used to be that the bot could sort of sense what you were trying to say and put it into different colloquialisms, which was even fun because it was like, “I know what you’re trying to say here, how about…” Now it’s in parts too stupid to translate the simplest sentences correctly, and the suggestions it makes are at times as moronic as those made by Google Translations.

    If this is a deep-learning AI that learns from users’ translations and the phrases they choose most often – which, by the way, is a valuable, moneys worthwhile contribution of every free user to this project: They invest their time and texts, thereby providing the necessary data for the AI to do the thing as nicely as they brag about it in the first place – alas, the more unprofessional users discovered the translator, the worse the language of this deep-learning bot has become, the greater the aggregate of linguistically illiterate users has become, and the worse the language of this deep-learning bot has become, as it now learns the drivel of every Tom, Dick and Harry out there, which is why I now get their Mickey Mouse language as suggestions: the inane language of people who can barely spell the alphabet, it seems.

    And as a thank you for our time and effort in helping them and their AI learn, they’ve lowered the limit from what was once 5,000 to now 1,500…? A big “fuck off” from here for that! Not a brass farthing from me for this attitude and behaviour, not in a hundred years.

    Article Title: Reddit enforces user activity tracking on site to push advertising revenue
    Article URL: https://www.ghacks.net/2023/09/28/reddit-enforces-user-activity-tracking-on-site-to-push-advertising-revenue/

    No surprises here. This is just the beginning really. I cannot see a valid reason as to why anyone would continue to use the platform anymore when there are enough alternatives fill that void.

    I’m not sure if there is a point in commenting given that comments seem to appear under random posts now, but I’ll try… this comment is for https://www.ghacks.net/2023/09/28/reddit-enforces-user-activity-tracking-on-site-to-push-advertising-revenue/

    My temporary “solution”, if you can call it that, is to use a VPN (Mullvad in my case) to sign up for and access Reddit via a European connection. I’m doing that with pretty much everything now, at least until the rest of the world catches up with GDPR. I don’t think GDPR is a magical privacy solution but it’s at least a first step.
