Almost one million routers within the Deutsche Telekom have been put down due to a cyber-attack, which caused a country-wide Internet outage for about 900,000 users. According to the official information, the attack attempted to infect the routers with malware but have instead crashed small percentage of them; a software update is now available. It is likely that the attack was caused by the modified version of the Mirai worm which employs thousands of hijacked Internet of Things devices, Wired reports. German Office for Information Security reported that this was part of a global campaign to take down parts of the Internet, and issued a statement that the attack has also targeted government networks. The Director of the German intelligence agency has expressed concerns that this attack may be part of the campaign to disrupt forthcoming federal elections next year.
