Ukrainian agents on cyberoffensive against Russian troops

Sam Cranny-Evans, a communications and surveillance expert at the Royal United Services Institute think tank, said that while the communication issues mainly affected northern parts of Ukraine, the SBU was using interceptions to paint a picture of widespread chaos among Russian ranks. It's not clear that the Russians are struggling with this universally," he said, adding that some invading units had been using portable and secure satellite communication devices. He said that the publicly broadcast conversations were likely to be "tactical" and aimed at boosting Ukrainian morale, while "strategic" nuggets of information that could shape battles on the ground would be kept secret. "This is interesting because the world is really watching it for the first time," he said.
