The European Union recently issued a warning regarding a cyber-attack on any one member that state could merit a reply by all members of the bloc, in the middle of rising fears of hackers holding governments to ransom.
Similarly as we know, WannaCry, a huge ransomware attack happened last month linked to North Korea, caused worldwide chaos following crippling computer networks at companies and government agencies worldwide.
The EU foreign ministers meeting in Luxembourg said the 28-nation bloc was "concerned by the increased ability and willingness of state and non-state actors to pursue their objectives through malicious cyber activities."
"Such activities may constitute wrongful acts under international law and could give rise to a joint EU response" which can take in "restrictive measures" or sanctions, a statement said.
The WannaCry attack, which insisted that the victims should pay to recover use of their computers, there have been rising worry about likely foreign intervention in core state activities such as elections.
A chief theme in last year's US presidential campaign, with Moscow blaming of trying to sway the vote in errand of Donald Trump, and fears that have been voiced over what might happen in German elections in September.
