The latest strain of Mirai, the malware thats been infecting internet routers from Deutsche Telekom, has spread to at least 10 other countries, according to security firm Flashpoint. It’s still unclear how many devices have been infected, but Flashpoint estimates that as many as five million devices are vulnerable. The developers of this new strain probably wanted to make their Mirai botnet bigger, Flashpoint said. Security experts worry that hackers will continue to upgrade Mirai’s source code to infect additional devices.”]
