NCSC outlines ways to protect against WannaCry ransomware

The National Cyber Security Centre (NCSC) has published guidance on how to protect IT systems from the ‘WannaCry’ ransomware.

The NCSC also says that its working with affected organisations and partners to investigate and coordinate the response in the UK, following the recent attack that hit the NHS.

From investigations and analysis performed to date, we know that the malware encrypts files, provides the user with a prompt which includes; a ransom demand, a countdown timer and bitcoin wallet to pay the ransom into.

The malware uses the vulnerability MS17-010 to propagate through a network using the SMBv1 protocol. This enables the malware to infect additional devices connected to the same network.

The steps the NCSC advises can be found here.
