"You still have a lot of soldiers bringing cellphones to the frontline who want to talk to their families and they are either being intercepted as they go through a Ukrainian telecommunications provider or intercepted over the air," said Alperovitch.
"That doesn't pose too much difficulty for the Ukrainian security services."
"Security has always been a mess, both in the army and among defence officials," the source said.
