Hackers may be hijacking internet-connected fridges, toasters and light bulbs in order to use their computing power to mine bitcoins, researchers have revealed.
IBM researchers discovered a bitcoin mining component in a new variant of Mirai—a form of malware that exploits security vulnerabilities to take control of devices connected to the so-called Internet of Things (IoT).
Security firm McAfee recently estimated that more than 2.5 million IoT devices were infected by the Mirai botnet in 2016, though it is not clear how many compromised devices may have been used to mine the virtual currency.
“We do not have any insight into whether or not bitcoins were actually mined during these attacks,” Dave McMillen, a senior threat researcher at IBM, tells Newsweek. “It is also not known whether or not this is the actions of one group or many… This Mirai variant could be appealing to others in the future due to the potentially large volume of devices that could be involved.
