Whilst Ransomware is not new, the recent spate of high profile attacks on critical infrastructure such as Healthcare, transport and finance have revealed just how effective the latest variants are. With the massive impact caused by the WannaCrypt(WannaCry) Ransomware many copycats are anticipated. Indeed modified strains have already been discovered.
In their current state many Industrial Control Systems (ICS) are at risk from Ransomware. Simply relying on an air gap is not a sufficient safeguard against ransomware which can also affect embedded operating systems.
Although the initial Cyber-attack was slowed over the weekend, new variants of the WannaCry ransomware have already started emerging and TES CyberSafe Team expect new variants to emerge all week causing havoc all across the globe.
Our advice is to visit the NCSC website (www.ncsc.gov.uk) & keep up to date with the latest news.
Microsoft has also released security updates for unsupported systems: https://goo.gl/CKwfh8
