5 ways to become a smaller target for ransomware hackers

A top Russian mobile operator said Friday it had come under cyberattacks that appeared similar to those that have crippled some United Kingdom hospitals.

A security guard stands outside the Telefonica headquarters in Madrid, Spain, Friday, May 12, 2017.

The company also reiterated a call it made earlier this year for an global agreement among states to shield civilians and corporate noncombatants from hacking.

CERT-In, the government's cyber security arm, has maintained that apart from five or six isolated instances, there are no reports of a substantial scale to indicate that Indian systems have been hit.

Cyber security experts predict that the scope of the attack could expand as people return to work and resume their work on computers, CNN reported on Monday.

"And also existing known infections can spread, we can't say what scale the new cases will occur at but it's likely there will be some".

"The numbers are still going up", Wainwright said.

Officials and experts today urged organizations and companies to update their operating systems immediately to ensure they aren't vulnerable to a second, more powerful version of the malicious software.

Cybersecurity experts say the unknown hackers who launched this weekend's "ransomware" attacks used a vulnerability that was exposed in NSA documents leaked online.

He argued there should be "a new requirement for governments to report vulnerabilities to vendors, rather than stockpile, sell, or exploit them".

The Japan Computer Emergency Response Team Coordination Center, a nonprofit providing support for computer attacks, said 2,000 computers at 600 locations in Japan were reported affected so far.

The government is not legally bound to notify at-risk companies.

Senior U.S. security officials held another meeting in the White House Situation Room on Saturday, and the Federal Bureau of Investigation and the National Security Agency were working to help mitigate damage and identify the perpetrators of the massive cyber attack, said the official, who spoke on condition of anonymity to discuss internal deliberations.

Mr MacGibbon declined to comment on the identity or type of the business impacted by the unprecedented cyber attack but said it was a small company, which did not provide critical infrastructure.

It is believed to be the biggest online extortion recorded.

The problem is that numerous Nation's computers have been turned off all weekend - and there are fears that when users return to work today, the virus could again be spread by unsuspecting users.

Clapper, who served as intelligence director under President Barack Obama, calls it a "very serious, serious problem".

The 200,000 victims included more than 100,000 organizations, Europol spokesman Jan Op Gen Oorth told The Associated Press.

However, he said that so far "remarkably" few payments had been made by victims of the attack.

He said it was too early to say who is behind the onslaught and what their motivation was. The British Home Secretary said most of the NHS systems were back to normal by midday Saturday. So the true effect of the attack may emerge on Monday as employees return and log in. As a loose global network of cybersecurity experts fought the ransomware hackers, Chinese state media said 29,372 institutions there had been infected along with hundreds of thousands of devices. It crippled the British health care system for a day, infecting almost 20 percent of its health care groups, forcing medical treatments to be canceled or postponed for thousands of people.

Moreover, copycat variants of the malicious software behind the attacks are likely to spread, because the malware uses mostly open-source code and is easily replicable.

The Microsoft President also added: "The governments of the world should treat this attack as a wake-up call".

What has tech security experts really anxious about this development is the fact that more exploits were released during the NSA leak than what caused last week's attack.
