According to a blog post published by security firm Trustwave, a wide-scale cyberattack was launched on MicroTik routers late last month.
The effort led to the installation of the Coinhive mining software in a “mass” infection of more than 17,000 devices.
Trustwave security researcher Simon Kenin said that all of the devices used “the same site key,” indicating that one entity reaped the mined tokens from all of the devices.
Mr. Kenin “This attack may currently be prevalent in Brazil, but during the final stages of writing this blog, I also noticed other geo-locations being affected as well, so I believe this attack is intended to be on a global scale.”
According to a previous post by Trustwave, also co-authored by Kenin, Coinhive gained traction in 2017 as a service that claimed to provide monetizing solutions for websites without using any advertisements.
However, mining reportedly ended up costing site visitors up to 99 percent of their CPU processing power, leading to further issues for consumers as their devices generated more heat and used up large amounts of electricity.
Mr. Kenin also reports that illicit cryptocurrency mining operations such as these are “a trend we’ve been seeing a lot of over the last three years, as attackers shift from ransomware into the world of miners.”
