Running Windows? How to protect against the big ransomware attack

"Ransomware as a service, it's a lucrative business", he said.

Home Secretary Amber Rudd said 48 NHS trusts were affected and all but six were now back to normal.

Hundreds of hospitals and clinics in the British National Health Service were infected on Friday, forcing them to send patients to other facilities.

Whether you manage a network or only have one computer, you should download security updates as soon as they are available - no matter what operating system you use.

And all this may be just a taste of what's coming, a cyber security expert warned.

East finals trip on line for Wizards, Celtics
Neither team has won on the other's court this season and Washington hasn't won in Boston since the 2014 regular season. The Wizards came up short of becoming the first team in this matchup to win on the opponent's home floor in 2016-17.

Some victims were ignoring official advice and paying the $300 ransom demanded by the cyber criminals to unlock their computers, which was due to double to $600 on Monday for computers hit by Friday's first wave.

Businesses around the world scrambled on Saturday to prepare for a renewed cyber attack, convinced that a lull in a computer offensive that has stopped vehicle factories, hospitals, schools and other organizations in around 100 countries was only temporary. But it appears to be "low-level" stuff, given the amounts of ransom demanded, Eisen said Saturday.

"[Computers] used to be small rectangles, now it's this whole thing", says Belfiore. "There's no barrier to do it tomorrow to 100 million computers". "They're just a huge organisation which has had insufficient investment in computer security over the years".

But the hackers do not appear so far to have been well rewarded: only about $50,000 has been transferred to their online wallets so far, according to Elliptic Labs which tracks transactions using the internet currency bitcoin.

An executive at a cybersecurity firm that helped block a global ransomware attack says new variations of the malicious worm are circulating and researchers expect one to develop that can't be stopped. A security researcher who goes by the name MalwareTech has activated a sort of kill-switch in WannaCry that stops it from spreading.

Ivory Coast soldiers begin receiving bonuses - mutiny spokesman
Ivory Coast is the world's largest producer of cocoa and London futures climbed to a five-week high on Monday due to the unrest. The Abidjan-based African Development Bank [AFDB.UL], which employs several thousand people, told its employees to stay home.

Lieu, who noted on his Web site that he is "one of only four computer science majors serving in Congress", supports changing the vulnerabilities equities process (VEP) to ensure greater transparency in how the federal government notifies software companies about bugs it identifies. His action couldn't help those already infected, however.

Microsoft released a patch that defended against WannaCry-like attacks in March. Windows, Microsoft Office and Microsoft Azure offer developers more than a billion opportunities to connect their innovations with Microsoft customers.

The extortion attack, which locked up computers and held users' files for ransom, was believed the biggest of its kind ever recorded, disrupting services from the Russia, Spain and India.

Apple's Mac computers were not targeted by this ransomware attack so are clear. Russia's central bank said Saturday that no incidents were "compromising the data resources" of Russian banks. The temporary halt in production was a "preventative step", Renault said, giving no details on how badly the plant was affected by the malware. Microsoft requires Windows 10 customers to automatically update their computers, but some people with older PCs disabled automatic updates. "I didn't open any link", she said. The tools were made public by a hacking group called the Shadow Brokers.

In Spain, major firms including Telefonica were hit, with employees told to shut down workstations immediately through megaphone announcements. In this May 12, 2017 photo, a display panel with an error can be seen at the main railway station in Chemnitz, Germany.

Police warn: If you're hit by cyberattack, don't pay the ransom
Kyodo News said one personal computer was affected at one office at East Japan Railway Co., but train services were not affected. Op Gen Oorth said today it was still "a bit early too say who is behind it, but we are working on a decrypting tool".
