Cryptocurrency Mining Malware Infects 170K Devices
A cryptocurrency mining malware has managed to break into more than 170000 devices within Brazil during July. Trustwave, a cybersecurity company, reported that the massive crypto jacking attack infected MicroTik routers in July. This method leads to mining software known as Coinhive and spread massively to infect the devices.
A Connected Infection
Simon Kenin, a security researcher at Trustwave stated that all of the exposed devices were connected through the usage of one sitekey which points to just one figure siphoning all the successfully mined cryptocurrencies from the infected devices.
As written by the researcher, he states that the current attack maybe excelling in Brazil although he had noticed several other locations experiencing the same method of malware usage and believes that the attack was meant as an international event. An older post by co-written by Simon Kenin said that the Coinhive malware saw launch and growth last year by claiming it was an ad-free monetizing service for websites as part of a script embedded into the website to control the CPU and mine for Monero, another cryptocurrency.
In the end, websites saw their CPU processors pumping out power at 99 percent operation which resulted in over-heating user devices and massive power consumption. Since then, the cybersecurity company has launched a solution to render the malware useless and as Kenin has stated in his latest publishing, he stresses on the importance of applying the latest patches to any MikroTik routers immediately to avoid exposure to the malware again and stop its global spread.
He also mentioned the shift from ransomware to malware and its rise over the last three years. Skybox Security, another cybersecurity company, also shares the same views and opinions as Trustwave and announced their own mid-year report of 2018 in which mining malware had climbed to 32% of all digital criminal attacks and ransomware has dropped to around 8%.
