(Reuters) – Chinese telecom equipment manufacturer Huawei has a hidden "back door" online from a large Dutch telecommunications company, which makes it possible to gain access to customer data, writes De Volkskrant on Thursday and cites unidentified information sources.  The newspaper said the Dutch intelligence service AIVD investigated whether the situation had made it possible to spy on the Chinese government.
Huawei said it was "surprised" by the Volkskrant report and that it would not respond to their basic claims that they came from anonymous sources.
Earlier, a company representative was quoted in De Volkskrant and said that Huawei followed all the laws in all countries where it works and "keeps the door closed to governments or others who want to use our network for activities that could threaten cyber security."
An AIVD spokesman said the agency would not comment on the Volkskrant report.
In April, the agency said the id was "unwanted for the Netherlands … to rely on hardware or software from companies from countries that run active cyber programs against Dutch interests", naming China and Russia.
Of the three major Dutch telecommunications companies KPN and VodafoneZiggo refused to comment on the report, while T-Mobile / Tele2 said it was not aware of any AIVD survey.
The report comes one day after US President Donald Trump banned Huawei from buying vital American technology without special approval and effectively impeding its equipment from the US telecom network at the national security site.
Last month, KPN said it would exclude Huawei's "core" equipment from the cellular network in the future, but would continue to use the Huawei radio tower.
A Dutch government panel is currently reviewing security guidelines to prevent spying prior to the construction of the country's 5G mobile network. Foreign Minister Stef Blok said at a press conference on Wednesday that the panel would make a decision "soon" if Huawei were to be allowed as a supplier.
The Volkskrant story contained no information as to whether the alleged "back door" was hardware or software, how it works or whether it was actually used.
