The virus spread quickly because the culprits used a digital code believed to have been developed by the US National Security Agency - and subsequently leaked as part of a document dump, according to researchers at the Moscow-based computer security firm Kaspersky Lab.

The researcher, who uses the pseudonym "MalwareTech" for personal security, registered a domain name buried in the code of the attack and was surprised to discover that it was the kill switch that sent a signal to stop the attacks. There were no reported cases in New Zealand. "We verified it and turned the information over to the Federal Bureau of Investigation".
"Hence, I do not think that machines will be particularly vulnerable to such malware attacks, which encrypt files", said the CEO of an ATM manufacturing company. "Potentially hundreds of thousands and into the millions".
As terrifying as the unprecedented global "ransomware" attack was, cybersecurity experts say it's nothing compared to what might be coming - especially if companies and governments don't make major fixes.
