James Wagner (Google’s Extensions Platform Product Manager) has stated that, due to the increase of malicious extensions with hidden mining scripts that run in the background without consent or knowledge of users, they have been forced to prohibit these type of extensions.

According to James, the Google Chrome Web Store allowed the use of extensions for the mining of cryptocurrencies as long as it was the extensions only purpose and the user had knowledge and agreed with the processes that were going to be executed on the machine.

Unfortunately, as he James stated, about 90% of the criptomining extensions violated these simple rules and have been forced to prohibit them. They have published this also in their developer program policies where all the permitted and forbidden actions on this platform are listed.

This decision is only taken to protect its users and prevent them from being victims of these malicious programs.

What are mining scripts?

Mining scripts are programs that are used, as their name suggests, to undermine cryptocurrencies. In many cases they are legal programs and the users who download them use them for their own benefit and to be aware of their activity.

The problem occurs when the mining script is hidden in a web or program and “infects” the computer, mobile or tablet to mine cryptocurrencies for another person.

And not only does it affect them by ignorance, the mining of cryptocurrencies makes the workload of our equipment increase in large quantities, giving an extra workload to our graphic cards or processors, which makes their useful lifespan shorten and a slowness in the process load is noticed.Cases of use and infection of mining scripts.

Cases of usage and infection of Mining Scripts.

There have been several cases of websites that have used or have been infected with mining scripts, which infected their visitors while they were in them, for example:

The Pirate Bay:

The famous download page had several complaints from its users in September 2017, who noticed how navigating in this website their processors increased consumption by more than 80%. The response of the Pirate Bay team was that they are using these Scripts as an alternative financing method to advertising.

Linux servers:

Last March, Trend Micro (a leading computer security company) discovered how an old mining script was being used to mine Monero on Linux servers, mainly in China, Japan, Taiwan, India and the USA.

According to a report by Troy Mursch, about 50,000 websites that use WordPress could be infected with malware for cryptocurrency, usually in form of Monero (due to their privacy and anonymity), which makes them impossible to trace.
