US President Donald Trump has admitted that he spoke with Russian President Vladimir Putin about the prospect of forming a cybersecurity unit at the G20 summit which was held last week in Hamburg, Germany. The scrutiny over cybersecurity has intensified following the recent ransomware attack which destabilized hundreds of businesses and institutions like the NHS in the UK.

A number of US and European energy companies have been penetrated by a group of sophisticated hackers in a cyber espionage campaign. The cyber-attack successfully infiltrated some of the core systems that control the firms operations according to reports from researchers at security firm Symantec.
