Kochi: The National Investigation Agency (NIA) has revealed that the Keralite youths, who were arrested for their alleged links with terror outfit Islamic State, had communicated with one another using a sophisticated encrypted email app - Tutanota.
Unlike other mail services, the messages sent from this app do not get saved on the server. The messages can be accessed only in the devices that were used to send and receive them and not even the service providers can access them. Once deleted, it is not possible to retrieve the information from the phone or computer, reports said.
It has been found that the messages were sent from fake SIM cards procured by Manseed, who was among the six Keralites arrested earlier this month for their links with the international terror outfit. The NIA has also retrieved a tablet computer used by Manseed's wife.
At least 21 youth from Kerala were reported missing and are suspected to have joined ISIS in Afghanistan.
