<p>Sources in the agency said they are suspecting that a malicious software code was programmed to attack the Common Use Passengers Processing System (CUPPS) which controls the airline reservation system.<br /><br />The CBI, which took over the case, is suspecting a cyber attack rather than a technical snag but it is yet to locate the source of the code as the investigations are at preliminary stage, sources said.<br /><br />However, they said the code seems to have come from a remote location. The problem resulting from this alleged hacking attempt brought down the CUPPS on the afternoon of June 29 resulting in collapse of counters of all airlines at T-3.<br /><br />The system which also informs about expected time of arrival and departure of flights could only be restored after 12 hours, forcing the authorities to turn to manual mode which caused delays in flights and waiting time for passengers.<br /><br />The agency has registered the case under the IT Act against unknown persons, they said. The CBI has sought all records of the CUPPS which is maintained by Aeronautical Radio Incorporated, they said, adding that the probe is at preliminary stage and any indication about the source of the code will become clear after scrutiny of all the log details.</p>
