How to protect yourself from the massive worldwide cyberattack

How to protect yourself from the massive worldwide cyberattack

Krishna Chinthapalli, a doctor at Britain's National Hospital for Neurology & Neurosurgery who wrote a paper on cybersecurity for the British Medical Journal, warned that British hospitals' old operating systems and store of confidential patient information made them an ideal target for blackmailers.

Researchers believe spying tools developed by the US National Security Agency were used in the attack that hit worldwide shipper FedEx, disrupted Britain's health system and forced a European carmaker to halt some production lines.

Ori Eisen, an expert in Arizona, says the attack Friday that held hospitals, factories and government agencies hostage around the world appears to be "low-level" stuff, given the ransom demands.

NHS trusts have today requested new patients do not come to A&E, but instead to ring 111, or 999 in the case of an emergency.

Ms Rudd said: "Of the 48 that have been impacted, a lot of them are back to normal course of business".

Residents attending the hospital have been asked to remain patient, but hospital bosses have advised that they should present for appointments as normal.

Patrick Ward, 47, a sales director at Purbeck Ice Cream, from Dorset in England, poses for photographs after giving media interviews after his heart operation scheduled today was cancelled because of a cyberattack, outside St Bartholomew's Hospital in London, Friday, May 12, 2017.

All A&Es are back up and running after a cyberattack hit nearly one in five NHS England trusts, Amber Rudd has confirmed.

Mr Norris, a senior systems engineer at cyber security firm Tripwire, said: "So it's pretty sure that as the weekend goes through and by the beginning of next week, we're going to start see more and more organisations suffer because of weakened security controls - really basic security hygiene".

Rudd is to chair an emergency meeting of the government's Cobra committee on Saturday afternoon.

"The response has in fact been very good", she said.

Thousands Of Ransomware Cyberattacks Reported Worldwide
Those affected see a message on their computer screens demanding payment in the digital currency bitcoin to restore access. Once it infects the PC, it'll encrypt all the files on the machine, and then demand the victim pay a ransom to free them.

The NHS was working on Saturday to bring its systems back online after it became the highest-profile victim of the so-called WanaCrypt0r attack and faced renewed concern about the strength of its infrastructure.

Most of the affected hospitals were in England, but several facilities in Scotland also reported being hit. "Ambulances are being diverted to neighbouring hospitals".

The assault is part of an attack that has affected organisations in more than 70 countries, including the United States, China, Russia and Spain, disrupting power and telephone companies.

British based cyber researcher Chris Doman of AlienVault said the ransomware "looks to be targeting a wide range of countries", with initial evidence of infections in at least two dozen nations according to experts from three security firms.

The hack happened four weeks before a British general election in which national security and the management of the state-run National Health Service are important issues.

"You can decrypt some of your files for free", reads the message, which we're seeing in a variety of languages.

The attack came after warnings of NHS vulnerability, with cybersecurity allegedly neglected despite a series of attempted hacks.

Cyber security expert Paul Norris said large networks are particularly at risk as the virus continues to spread.

"Like many other companies, FedEx is experiencing interference with some of our Windows-based systems caused by malware". When he tried to access patient files on a computer, he couldn't find them - even though he knew they were there.

First, there were reports of Spain's largest telecom being hit with pop-up windows demanding a $300 ransom, paid in the cryptocurrency bitcoin, to access files.
