May 1, 2019//-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 given Huawei 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.
Vodafone asked Huawei to remove backdoors in home internet routers in 2011 and received assurances from the supplier that the issues were fixed, but further testing revealed that the security vulnerabilities remained, the documents show.
Vodafone also identified backdoors in parts of its fixed-access network known as optical service nodes, which are responsible for transporting internet traffic over optical fibers, and other parts called broadband network gateways, which handle subscriber authentication and access to the internet, the people said. The people asked not to be identified because the matter was confidential.
A backdoor, in cybersecurity terms, is a method of bypassing security controls to access a computer system or encrypted data. While backdoors can be common in some network equipment and software because developers create them to manage the gear, they can be exploited by attackers.
In Vodafone’s case, the risks included possible third-party access to a customer’s personal computer and home network, according to the internal documents.
The Trump administration, arguing such end-runs around security in Huawei’s equipment could invite espionage by the Chinese state, is trying to persuade Western allies to block the company from the next generation of mobile networks. Huawei has repeatedly denied that it creates backdoors and says it’s not beholden to Beijing.
