Overheen 500 million people are inadvertently mining cryptocurrencies through their computers after visiting websites that are running background mining software, researchers have discovered.

Research by ad blocking rock hard AdGuard found 220 popular websites with an aggregated audience of half a billion people use so-called crypto-mining scripts when a user opens their main pagina.

Visitors to the websites come from all overheen the world but the worst affected country is the U.S., with Eighteen.7 procent of websites engaged ter using in-browser cryptocurrency mining scripts coming from the United States.

The mining instrument works by hijacking a computer’s central processing unit (CPU), commonly referred to spil “the brains” of a laptop. Using part of a computer’s CPU to mine bitcoin effects the machine’s overall vertoning and will slow it down by using up processing power.

The researchers found that bitcoin browser mining is mostly found on websites “with a shady reputation” due to the trouble such sites have with earning revenue through advertising. However, te the future it could become a legitimate and ethical way of making money if the webstek requests the permission of the visitor very first.

“220 sites may not seem like a loterijlot,” the researchers wrote te a blogpost detailing their discovery. “But CoinHive wasgoed launched less than one month ago on September 14. The growth has bot utterly rapid: from almost zero to Two.Two procent of Alexa’s top 100,000 websites.

“This analysis well illustrates the entire web, so it’s safe to say that one of every forty websites presently mines cryptocurrency (namely Monero) ter the browsers their users employ.”

AdGuard estimates that the profit for the websites presently stands at around $43,000. This may not seem like a very high figure considering the number of computers affected, but it is still considerable given the timeframe and the fact it wasgoed done at almost zero cost.

The record-high price of bitcoin, which is $Five,655 at the time of writing, is an incentive for websites and cyber criminals to profit from cryptocurrency mining software, such spil Coinhive and JSEcoin.

The world’s most valuable cryptocurrency now has a market capitalization of almost $100 billion and is presently being boosted by rumors China could switch roles a latest kerkban on exchanges.

Mining bitcoin—the process of confirming bitcoin transactions and adding their record to bitcoin’s public ledger te order to generate fresh units of the currency—requires vast amounts of computing power, however newer cryptocurrencies like Monero with lower market value are lighter to mine.
