Riga International Airport officials admitted the homepage of the airport could be hacked, but denied that this posed a threat to air traffic safety. Air traffic control was based on a seperate computer network which could not be reached through the homepage www.riga-airport.lv.
It was the first official confirmation by airport officials (speaking to the news agency LETA) that vulnerabilities reported on this blog and the press existed.
This blog and the report in my day-job newspaper never suggested that flight operations (air traffic control) was threatened, merely that access to the airport's intranet and mail systems could expose confidential information about anti-terrorist measures and contingency plans. I don't know what speculation was reported in other media.
The source who demonstrated an apparent ability to control the airport's server said that the intranet and mailserver were vulnerable, but deliberately avoided attempting this. The source (whom I called WhiteHat) is connected to a reputable IT-related company and said that making an attempt to penetrate the airport's corporate intranet would be going one step too far without the consent of airport authorities.
