"Based on the research, the flaws have been present in ZTE smartphones since they were in the manufacturing phase. Because of this, they have remained unknown to the public until now. The study did not identify if some hackers have exploited the vulnerabilities for their own benefit. "
"The Department of Homeland Security initially declined to name the companies behind smartphones that were found to have the manufacturing vulnerabilities. However, ZTE outright confirmed that its smartphones have the flaws. It is actually the first manufacturer to acknowledge the problem."
I wonder how many and who the others are.
