Ransomware attack should be a 'wake-up call' for governments

Ransomware: Wave of cyberattacks sweeps the globe

Ransomware: Wave of cyberattacks sweeps the globe

"So they no longer get the security updates they should be". A large cyberattack crippled computer systems at hospitals across England on Friday, with appointments canceled, phone lines down and patients turned away.

The phenomenon of companies failing to update their systems has been a persistent security problem for years.

In that regard, the institution called on all sectors to solve their problems in the field of cyber-security.

The hackers remain anonymous for now, but it appears that they are amateurs. It is believed that 200,000 organizations have been affected in 150 countries, including Russia, Spain, and the United States.

So criminals turned to targeted attacks instead to stay below the radar.

Companies and governments spent the weekend upgrading software to limit the spread of the virus.

Microsoft will also introduce the Timeline which works much like a time portal on a computer.

On Friday, a security researcher inadvertently created a "kill switch" to help stop the spread of this ransomware.

Copycats are already starting to pop up, according to security experts.

The Beijing News said Sunday that students at several universities around the country reported being hit by the virus, which blocked access to their thesis papers and dissertation presentations.

Further, Suiche stopped another variant when he registered the new kill-switch domain name, but said industries must expect that there is still more to come.

This includes whitelisting certain websites and software so only approved programs can run on a computer, or disabling administrative privileges on a company's machines so that only the IT department can download programs.

First, there was a highly risky security hole in Microsoft Windows, which became known after hackers leaked tools that were apparently created by the U.S. National Security Agency to exploit the hole. The exploit was leaked last month as part of a trove of USA spy tools.

The news is also likely to embolden cyber extortionists when selecting targets, Chris Camacho, chief strategy officer with cyber intelligence firm Flashpoint, said. It locks down all the files on an infected computer. Some have also been machines involved in manufacturing or hospital functions, hard to patch without disrupting operations.

NHS Digital, which oversees United Kingdom hospital cybersecurity, said it sent alerts about the problem - and a patch to fix it - to health service staff and IT professionals last month.

FedEx, Nissan, and the United Kingdom's National Health Service were among the victims.

But how does WannaCry stack up against previous computer worms?

In Spain, the attacks did not disrupt the provision of services or networks operations of the victims, the government said in a statement. "It was clear [that] warnings were given to hospital trusts". By providing a single place for all files to be saved in, Microsoft allowing multiple devices a way to be more organized and prevent loss of important files.

Chinese government bodies from transport, social security, industry watchdogs and immigration said they had suspended services ranging from processing applications to traffic crime enforcement. These alerts included a patch to protect their systems. "We don't have a precedent for something of this scale (in China)", said Marin Ivezic, a cybersecurity expert at PwC in Hong Kong. The statement said antivirus systems are working to destroy it.

Elsewhere in Asia, the impact seems to have been more limited. It also allows the user to pick up an existing project, which means that the user can start their work directly on a computer where they left off.

The Shadow Brokers released Eternal Blue as part of a trove of hacking tools that they said belonged to the U.S. spy agency.

British Home Secretary Amber Rudd - who was chairing a government emergency security meeting on Saturday in response to the attack - said 45 public health organisations were hit, though she stressed that no patient data had been stolen.
