Recently, Google has dealt with cryptocurrency mining extensions by banning all mining problems from the Chrome Web Store.

These extensions have proved to be controversial in recent months, with many Chrome extensions harnessing the processing power of unsuspecting internet users to mine cryptocurrency remotely without their knowledge, an activity which slows down user devices. Now, Archive Poster, i.e. a popular Chrome extension supposedly designed for managing Tumblr posts, was discovered to be mining Monero from hundreds of thousands of different devices in secret and without permission, a malicious activity now known as “cryptojacking”. An Android app was, in fact, caught cryptojacking millions of devices in January, also mining Monero.


While Google had already banned malicious cryptojacking apps, this recent ban took things a step further with a blanket ban that removes all extensions designed for mining, even those openly designed for that purpose. Google, in fact, released a statement yesterday outlining the reasons behind the ban, saying “90% of all extensions with mining scripts that developers have attempted to upload to Chrome Web Store have failed to comply” with their new mining policies, recently implemented to detect malicious mining extensions. As of yesterday, no new cryptomining extensions are being accepted, and existing extensions would be all be de-listed by late June. Google had also clarified that blockchain extensions with non-mining functions were still welcome and under no threat at this time.

Cryptomining extensions had been arguably popularized by torrent site The Pirate Bay, which began harnessing user’s CPU power last year in an attempt to monetize the site. Since then, bad actors have attempted to capitalize on the trend through malicious apps and extensions that are now making it difficult for legitimate versions to survive.

Here it also needs mentioning that casual users weren’t the only ones to fall prey to covert cryptomining operations recently. For instance, a Russian nuclear facility was allegedly compromised by its own staff when one of Russia’s most powerful supercomputers was discovered to have the covert cryptomining software installed and operating. The nuclear supercomputer is supposed to remain offline at all times for security purposes, and the breach got apparently discovered when the scientists allegedly attempted to connect the computer to the Internet.


Tesla had fallen prey to a cryptojacking incident recently along with government websites throughout the US, UK, and Australia, even Google’s own DoubleClick Ad service was used to illegally distribute mining software to unsuspecting users. While many casual internet users would reportedly be glad to sacrifice some CPU power in exchange for ad-free browsing, this ban would definitely force at least 200 million Chrome users to look elsewhere.

The decision arrives just at the juncture and in quick succession after Google’s decision to ban ICO advertisements starting from June, with Twitter and Snapchat following suit.
