CBS News Texas reached out to both DFW International Airport and Dallas Love Field for comment:

“DAL has not had any reported or confirmed cases of malicious software detected in the airport’s USB ports/outlets. We also do not have standalone phone charging stations.

DAL electrical technicians inspect outlets and USB ports nightly and report any unusual devices or evidence of tampering. Passengers are encouraged to do the same before their usage. As always, we urge…
