Zero day vulnerability, Wannacry

Greetings Citizens of the world, we are Anonymous.

A zero-day vulnerability tool, covertly exploited by US intelligence agencies and exposed by the Shadow Brokers hacking group has been blamed for the massive spread of malware that infected tens of thousands of computer systems globally.

The ransomware virus which extorts Windows users by blocking their personal files and demanding payment to restore access, allegedly exploits a vulnerability that was discovered and concealed for future use by the National Security Agency, according to a range of security experts.

“Our analysis indicates the attack, dubbed “WannaCry”, is initiated through an SMBv2 remote code execution in Microsoft Windows. This exploit (codenamed “EternalBlue”) has been made available on the internet through the Shadowbrokers dump on April 14th, 2017. Russian cybersecurity firm, Kaspersky Lab, wrote in a blog post about the attack.

Although Microsoft had already patched the backdoor roughly a month before it became public, many users who did not install the latest security updates seem to have become the primary victims of the attack.

The worm has reportedly hit universities, a major Spanish telecom, FedEx, and the Russian Interior Ministry.

The NHS services across England and Scotland were also one of the major companies to have been hit by the large-scale cyber-attack and this has disrupted hospital and GP appointments.

Some hospitals and GPs have been unable to access patient data, after their computers were locked by a ransomware program demanding a payment worth £230. But there is no evidence patient data has been compromised, NHS Digital said.

Roughly 40 NHS organisations and some GP practices have been hit. The NHS in Wales and Northern Ireland has not been affected though.

There is no indication of who is behind the attack yet, but the hackers demanded their payment in the virtual currency Bitcoin, which is harder to trace.

Prime Minister Theresa May said: This is not targeted at the NHS, it’s an international attack and a number of countries and organisations have been affected.

Still though, it shows that these hackers have little disregard for their actions and will put other lives at risk in order to blackmail people out of their money.

In the video description, you can find a list of all NHS services that are known by the BBC to have been affected.

Now we’re going to show you a demonstration of how WannaCry ransomware works for research and security purposes.
