Cyber attack

NHS cyber-defender Marcus Hutchins charged in US

Marcus Hutchins, 23, has been accused of involvement with Kronos - a separate piece of malware used to steal banking logins from victims' computers.

Fellow cyber-security researchers have expressed surprise at the indictment.

The UK's National Cyber Security Centre has said that it was aware of the situation.

WannaCry spread rapidly through computer systems around the world, in an unprecedented outbreak that began on 12 May.

Shortly afterwards, Mr Hutchins was thrust into the limelight after he found a way to stop it from spreading.

Cyber-attack 'unprecedented' in scale

Europol has also warned a "complex international investigation" was required "to identify the culprits".

It's emerged that the tools used in the attack appear to have been stolen from the US National Security Agency.

There have been reports of infections in as many as 100 countries, including several in New Zealand, a live-tracking map of the attack showed.

European countries, including Russia, were among the worst hit.

Although the spread of the malware - known as WannaCry and variants of that name - appears to have slowed, the threat is not yet over.

Cyber attack knocks nearly a million routers offline

Last month, the Mirai botnet knocked the entire Internet offline for a few hours, crippling some of the world's biggest and most popular websites.

Now, more than 900,000 broadband routers belonging to Deutsche Telekom users in Germany knocked offline over the weekend following a supposed cyber-attack, affecting the telephony, television, and internet service in the country.

Chinese firm acknowledges inadvertent role in cyberattack

A Chinese firm that makes components for surveillance video cameras now admits their technology was used, in part, to carry out the unprecedented strike.

XiongMai Technologies acknowledged that a piece of malware known as "Mirai" that's spreading around the internet targets vulnerabilities in their products.

"Mirai is a huge disaster for the 'Internet of Things,'" XiongMai representative Cooper Wang told CNNMoney in an email. "[We] have to admit that our products also suffered from hackers' break-in and illegal use."

'Unprecedented' cyberattack involved tens of millions of IP addresses

Dyn, an Internet middleman company, was the target of the distributed denial-of-service, or DDoS, attack that hit in three waves. Dyn directs traffic when people type a URL into a browser. So the attack on the company caused temporary outages at many of the internet's most widely-trafficked sites.
