A Wuhan coronavirus (COVID-19) testing smart device sends data results immediately to the Centers for Disease Control and Prevention (CDC) and other federal and state health agencies.

The device in question is called Cue. According to its website, the smart device provides "reliable, easy-to-use COVID-19 tests with PCR-quality results delivered right to your mobile device in 20 minutes. No lab visits. No lines. No second guessing your results."

But Cue's website failed to mention the fact that the results of the tests are sent to the CDC and other relevant federal and state agencies.

"The Cue Health Mobile Application (Cue Health App) automatically reports test results according to the reporting guidelines of the appropriate public health authorities," reads one of Cue's fact sheets.

The smart device's privacy policy further states that the users acknowledge that the company has the right to share personal health information with the CDC and other federal and state agencies "as required for public health surveillance and related purposes."

The data that the Cue app sends to the CDC and other government agencies is vulnerable to alteration.

Ken Gannon, a security consultant, last month intercepted data sent by the Cue app before the test results could be sent to the mobile phone of a user. Gannon found that he could change the test result from negative to positive or vice versa.
