Covid-19, in the US stop the obligation to wear a mask on airplanes and trains


Stop wearing a mask on public transport in the United States. The decision comes following the ruling of the Florida federal judge who considered completely illegal the decision of the American authorities to impose the obligation of masks on means of transport such as trains and airplanes for a further two weeks.

How we read in the documents of Judge Kathryn Kimball Mizelle, the Centers for Disease Control and Prevention would have exceeded its legal authority under the Public Health Services Act of 1944. Not surprisingly, therefore, the further imposition of the mask obligation appears to be not only unconstitutional but also contrary to people's freedom of movement.

The obligation goes beyond the authority of the Centers for Disease Control and Prevention and violates the required procedures, explained Judge Kathryn Kimball Mizelle. - th_motorlabs_d_mh2_1 slot id: th_motorlabs_d_mh2 "); }
In our country the situation is quite different even if the final decision of the Italian government should arrive by the weekend. Although the management seems to be moving towards a recommendation for the use of masks indoors, the obligation for such safety devices could be extended in some contexts, such as on public transport.

A reflection that can be to do is to still keep the use of the mask for the means of transport. This is the position that I support and I hope that this synthesis can be reached, declared the Undersecretary of Health, Andrea Costa.

If the Biden administration has decided to suspend the obligation to wear a mask on public transport, following the ruling of the judge who considers the decision to extend the obligation on airplanes other means of transport to be illegal until May 3 , in Italy the line that the Government will take will probably be different.

A new bug in a Bluetooth at-home COVID-19 test could produce false results

A security researcher has discovered a bug in Cue Health’s at-home COVID-19 testing kit that could allow users to falsify results.

Cue Health's COVID-19 testing kit is a Bluetooth-operated molecular test that can detect a positive specimen in 20 minutes. The system tests for coronavirus using a nasal swab that is inserted into a single-use cartridge and analyzed by the battery-powered Cue Reader, and this then transmits the result over Bluetooth to the Cue Health app on the test-taker's phone. In March 2021, Cue’s system became the first molecular COVID-19 testing kit to receive emergency authorization from the FDA for at-home and over-the-counter use.

While the FDA at the time applauded Cue Health's innovative approach to COVID-19 testing, Ken Gannon, a security consultant at WithSecure, F-Secure's corporate security business, found a flaw in the testing kit that could allow test results to be modified.

It's the second time a security vulnerability has been discovered in a connected COVID-19 test by the same researcher who recently exposed a similar flaw in Ellume’s COVID-19 Home Test, calling into question the integrity of testing kits rushed to market under the federal government's emergency approval powers.

The vulnerability — now fixed — was found in how the Cue Reader communicates with the Cue Health app over Bluetooth using the Protobuf protocol, which presents the test data in an easily readable block of data. The block of data generated by the Reader ends in “10 02” for a positive COVID-19 test result, or “10 03” for a negative result. Gannon developed a script that enabled him to intercept and modify the data by manipulating these digits. By changing a single digit in the result, or 'bit-flipping,' Gannon could change his negative result to a positive result, as well as to obtain a certificate verifying the results as valid.

“The process is basically the same for changing a positive result to negative, which could cause problems if someone who knows how to do what I did decides to start falsifying results,” said Gannon. Negative COVID-19 tests have become requirements for many activities, including traveling into the United States.

“As of right now, the skill level required to flip those bits is somewhat high,' Gannon said. 'A person would need to have decent knowledge into hacking mobile applications and running custom code within Cue’s application. However, one thing I’m always worried about with Android application hacking is the ability to customize the hack so that the average consumer can do the same hack. Because of this, I’m purposely disclosing technical details and custom code that only reverse engineers could understand and use,' he added.

Gannon shared his research with Cue Health, which said it is not aware of any falsified test results beyond those reported by WithSecure, but said it has added server-side checks aimed at detecting manipulated results. Cue Health did not respond to TechCrunch when asked if the company had the means to detect the manipulation of results prior to WithSecure's findings.

Users should also update to the latest version of the Cue Health app.
