#CyberSecurityPulse: The Boom of JavaScript Miners

ElevenPaths    19 December, 2017

The most common question in recent months derived from the rebound in the value of numerous cryptocurrency is: Do I invest or not invest?

However, as we know, there are different ways to obtain cryptocurrencies and one of them is to start mining, but now it’s an expensive

option. It is at this point that the picaresque of certain attackers comes to light. Security researchers from F5 Networks spotted a

sophisticated malware campaign, tracked as Zealot campaign,

targeting Linux and Windows servers to install Monero cryptocurrency miners. Experts observed threat actors scanning the Internet for

particular unpatched servers and hack them with two exploits, one for Apache Struts (CVE-2017-5638) and one for the DotNetNuke ASP.NET CMS


Another recent case has been the one detected in the Starbucks of Buenos Aires where the clients’ computers were connected to their Wi-Fi and started to mine secretly. The notification to the company was made by the CEO of Stensul, Noah Dinkin, who made last December 2 a question through Twitter if they were aware of the situation. Dinkin commented in his tweet that JavaScript miner offered by Coinhive was being used to mine Monero cryptocurrency.

In this sense, ElevenPaths has recently published on its blog an investigation that explains why Monero is currently betting on and not Bitcoin, as well as which are the most attractive websites for those who want to take advantage of the computing capacity of third parties. Faced with this situation, projects have recently been published, such as NoCoin extension to detect if your computer is being mined. However, these efforts are still insufficient.
