More than 170,000 devices in Brazil were targeted in a cryptojacking attack last month.
According to a post published by security company Trustwave, a large-scale cyber attack was launched on MicroTik routers late last month. The effort led to the installation of Coinhive mining software into a "mass" infection of over 17,000 devices.
Security researcher Trustwave Simon Kenin wrote that all devices used "the same site key", indicating that an entity was reaping
It wrote:
"This attack could currently prevail in Brazil , but during the final stages of writing this blog, I noticed that other geographic areas have also been affected, so I think this attack is destined to be on a global scale. "
According to a previous post by Trustwave, he too – Kenin author, Coinhive has gained momentum in 2017 as a service that claimed to provide monetizing solutions for websites without using any advertising. Instead, site owners had to embed JavaScript code that would take over the power of the central processing unit (CPU) of site visitors to extract the cryptocurrency monarch.
However, mining would have ended up costing site visitors up to 99% of the CPU processing power, which led to further problems for consumers as their devices generated more heat and consumed large quantities of electricity.
Trustwave has subsequently released a detection tool to block mining malware and, as Kenin explains in his most recent post, readers should take into account his "warning call" and patch up all MikroTik devices "as soon as possible possible ", stressing that the severity of the attacks could reach" hundreds of thousands "of consumers worldwide.
Kenin also reports illegal cryptocurrency mining operations such as "a trend we've seen a lot in the last three years, since attackers move from ransomware to the miners' world."
These feelings are taken up by or other computer security companies such as Skybox Security have also reported in their mid-year update 2018 that among cybercriminals, encryption accounted for 32% of all cyber attacks, with ransomware represents 8%.
