Huawei noticed that New York Times had reported a backdoor in the Adups-supplied software pre-installed in Android mobile phones on November 15, 2016, which could send users' short messages to China. According to the report, online information of Adups shows that Adups provides software to Huawei.
The investigation is still ongoing. Huawei has already confirmed that Adups is not one of Huawei's suppliers, and Huawei has never carried out any business cooperation with them. Huawei PSIRT may update the security notice anytime and will provide the technical analysis and conclusion as soon as possible. Please stay tuned.
