A 19-year-old Canadian became the first person to be arrested in relation to the Heartbleed security breach.
Stephen Arthuro Solis-Reyes from London, Ontario was accused of hacking into the Canadian Revenue Agency (CRA)'s website last Friday by the Royal Canadian Mounted Police.
The RCMP say Mr Solis-Reyes then stole 900 social insurance numbers.
In a separate development, UK parenting site Mumsnet has provided fresh details about how it fell victim to the bug.
