According to the Health Ministry source, the hackers targeted five physical servers of the hospital, but the data from these five servers have been retrieved now.
Meanwhile, the hospital has also started functioning on online mode partially in some departments. The OPD appointment has been started through the online mode to some extent, a hospital source said on Wednesday.
The source said that some online and offline new and follow-up registrations have started being made at the new Rajkumari Amrita Kaur (RAK) OPD.
However, the online co-ordination between the ward admission and the discharge process has not been started yet. Therefore, the discharge is being done on the manual mode. The Smart Lab has also not been connected online yet in the hospital.
The AIIMS servers were reported hacked for the first time on November 23. A case of extortion and cyber terrorism was registered by the Intelligence Fusion and Strategic Operations (IFSO) unit of the Delhi Police two days later.
However, police had denied any random demand from the hospital. Delhi Police in a statement had said that no such demand has been brought to the notice of AIIMS administration.
