Poorly-secured smart energy meters could place millions at risk from hackers, warns GCHQ

New smart energy meters that are set to be installed in 27 million homes across the UK have been flagged by GCHQ for featuring vulnerabilities that could easily be hacked by criminals to expose millions of Britons to cyber attacks.

Smart energy meters being offered by the government could be hacked by criminals to inflate energy bills, falsify readings, or could be used by hackers to gain access to other smart devices they are connected to.

Last year, the UK's largest energy providers such as British Gas, E.on, Npower, Scottish Power and EDF announced that they were either testing or rolling out SMETS 2 meters, the second-generation smart energy meters that the government wanted to be installed across all 27 million households in the UK.
