FDA Guidance Fails to Ensure Security of 3D-Printed Masks and PPE

New Brunswick, N.J. (Sept. 16, 2020) – FDA guidelines for making 3D-printed masks, face shields and other personal protective equipment (PPE) in the COVID-19 era fail to defend against cyberattacks, according to Rutgers and Georgia Tech engineers.

Due to the shortage of medical PPE, 3D printing has become a good way to produce masks, face shields and other equipment. To ensure the security and safety of PPE, FDA guidelines should be expanded to guard against cyberattacks during the design of PPE, when printing is underway and after printing has ended, according to the engineers’ white paper.

For example, a rogue operator could design a 3D-printed mask with a malicious embedded part that connects an air filter to the mask. After the mask is printed, a cyberattack could change the structure of the part to let air bypass the air filter. Cyberattack detection tools such as artificial intelligence could be implemented to detect and thwart such attacks.

“Typically, the designer generates PPE design files and shares them on a cloud service and the 3D printing operator downloads and starts the manufacturing process,” said co-author Saman Aliari Zonouz, an associate professor in the Department of Electrical and Computer Engineering in the School of Engineering at Rutgers University–New Brunswick. “Potentially, a malicious designer could generate a malicious design file and start the printing process himself before distributing 3D printed objects to users.”

Many Americans continue to maintain unhealthy lifestyle habits during COVID-19; overeating, alcohol drinking and marijuana use increase while exercise declines, reports USC Center for the Digital Future
USC Annenberg School for Communication and Journalism

After more than six months of living in a pandemic, large percentages of Americans continue to indulge in unhealthy lifestyle habits, including overeating and increased use of alcohol and marijuana — all while many are exercising less, according to a study of the cultural impact of COVID-19 conducted by the USC Center for the Digital Future (CDF).

Houston Methodist COVID-19 study shows rapid spread and potential for mutant viruses
Houston Methodist

Molecular analysis of COVID-19’s powerful second wave in Houston shows a mutated virus strain linked to higher transmission and infection rates than the coronavirus strains that caused Houston’s first wave. Gene sequencing results from 5,085 COVID-positive patients tested at Houston Methodist since early March show a virus capable of adapting, surviving and thriving – making it more important than ever for physician scientists to understand its evolution as they work to discover effective vaccines and therapies.

Flu Season Returns As The COVID-19 Pandemic Continues
Johns Hopkins Medicine

As the COVID-19 pandemic continues with no end in sight, the annual flu season emerges once again. Cases of the flu have already begun to surface around the nation, and there are some reports of co-infection with COVID-19. Johns Hopkins Medicine experts say now is the time to take action to fight against the flu. Doctors recommend that everyone age 6 months and older get the flu vaccine each year to prevent infection from the virus or reduce the severity of the illness.
