Hundreds of thousands of Deutsche Telekom customers in Germany had their broadband service cut off following a hack-attack on its hardware.
At one point as many as 900,000 people suffered internet outages. That number fell to 400,000 as security measures were implemented.
The head of the company’s IT security is said the incident appeared to be tied to a botched attempt to infect customers’ routers with a new version of the malicious software known as Mirai.
The company, which has 20 million customers in Germany, has issued a software update and is asking affected customers to disconnect their routers.
