Google Web Store Bans Cryptomining Extensions

After finding that 9 out of 10 cryptomining extensions do not follow guidelines, the Google Web Store is planning to ban all cryptomining extensions for its Chrome browser by the middle of this year.

With the increasing popularity of cryptocurrencies such as Bitcoin, Monero, Ether, Litecoin and many others, cryptomining has not only become a serious pastime for some currency speculators, but a lucrative field for cybercriminals.
Now, Google is pushing back against the practice.
On April 1, Google announced that it would ban all cryptomining Chrome extensions from the companys Web Store by the end of the year. First, the company will no longer accept new cryptomining extension by developers as of Monday. Then, by the end of June, Google plans to delist all cryptomining Chrome extensions for good.
The exemption to this rule are Chrome extensions that perform a blockchain task not specifically related to cryptomining.

In Mondays blog post
, James Wagner, an extensions platform product manager with Google, wrote that nine out of ten cryptocurrency mining extensions had violated Google Web Store policies over the last several years, specifically by running mining scripts in the background without the users consent or permission, which can lead to performance and power problems with a device.
Those concerns over so-called cryptojacking led to the outright ban starting this wee.
Until now, Chrome Web Store policy has permitted cryptocurrency mining in extensions as long as it is the extensions single purpose, and the user is adequately informed about the mining behavior, according to the blog post. Unfortunately, approximately 90% of all extensions with mining scripts that developers have attempted to upload to Chrome Web Store have failed to comply with these policies, and have been either rejected or removed from the store.
The increasing popularity of cryptocurrencies, including a spike in the price of Bitcoin, which peaked at $19,000 at the end of December, has fueled interest in this market among a growing class of speculators.

It has become a haven for cybercriminals, who are taking advantage of the market volatility, as well as others who are looking to trick users into downloading cryptomining apps that can give their mining operation access to CPU and other resources from victims devices. (See

These rogue cryptomining operations can harm enterprises networks and infrastructure in several ways, whether its installing malware on phones -- even if the software is not stealing personal or corporate data -- slowing down and damaging hardware, or by simply jacking-up monthly electrical bills.
