Vodafone found hidden backdoors in Huawei equipment

For months, Huawei Technologies Co.has faced U.S. allegations that it flouted sanctions on Iran, attempted to steal trade secrets from a business partner and has threatened to enable Chinese spying through the telecom networks it’s built across the West.

Now Vodafone Group Plc has acknowledged to Bloomberg that it found vulnerabilities going back years with equipment supplied by Shenzhen-based Huawei for the carrier’s Italian business. While Vodafone says the issues were resolved, the revelation may further damage the reputation of a major symbol of China’s global technology prowess.

Europe’s biggest phone company identified hidden backdoors in the software that could have givenHuawei unauthorized access to the carrier’s fixed-line network in Italy, a system that provides internet service to millions of homes and businesses, according to Vodafone’s security briefing documents from 2009 and 2011 seen by Bloomberg, as well as people involved in the situation.
