Aviation blogger John Butler recently drew attention to a security flaw in the barcodes used on airline boarding passes that would allow terrorists or other criminals determine if they will be subjected to more intensive screening before boarding a flight.
He also reported that the flaw could allow them to modify that information to ensure they would not have to undergo certain measures.
According to Butler, the information in the barcode is unencrypted, allowing it to be read using a smartphone or other device.
The Transportation Security Administration declined to comment on these reports, but security expert Chris Soghoian commented that terrorists could use the vulnerability "to make sure the right guy is carrying the right bags."
