Firms around the world targeted in powerful cyber attack

Banks, government IT systems and energy firms around the world have all been targeted by a powerful cyber attack.

A Danish shipping company called Maersk – which has offices in Ireland and the UK – took to Twitter to state it’s one of the victims.  While details are continuing to emerge, experts say it’s thought to be a ransomware attack, similar to the WannaCry attack that occurred earlier this year.

British firm WPP – which is the biggest advertising group on the planet – says its computer networks in several locations are affected.  Russian, Indian and Dutch companies were also hit, while Ukraine says it’s suffered the biggest such hack in its history.
