All IT clients with Telefonix cybersecurity solutions were protected from the global ransomware which shut down organisations on Friday.
The WannaCry cyberattack spread with unprecedented speed and scale with 100,000s of victims in 150 countries, including the 47 NHS organisations with 1,000s of operations, tests and appointments disrupted.
The malware exploited a vulnerability in Microsoft Windows which was first identified by US intelligence. Microsoft released a security update in March to protect computers from the virus.
What we did in the wake of the NHS cyber attack
We took steps to investigate our clients' exposure to the risks as reported. Where appropriate, we applied the specific patch and run or set to run Windows Updates for our supported IT clients.
The best defence is a layered defence.
Firstly, you need to ensure you back-up your system. If all your data is backed up, you can recover from any ransomware.
Secondly, you need to keep your software up to date. Check with your business IT partner to ensure you have the latest Windows (Windows 10 or Windows 8.1 for operating systems) so you are automatically protected via Windows Update. Like updates on your smartphone, patches are updated automatically.
The downfall of some NHS Hospitals was the fact they ran Windows XP. This has been an unsupported operating system with no security updates for years and therefore provides no defence against these attacks.
Telefonix protects you and keeps your business running.
We work with award-winning next generation firewall and unified threat management leader Watchguard. Together, we provide better protection than traditional antivirus and firewalls that were unable to stop this ransomware.
The APT blocker sandbox analysis catches ransomware based on its behaviour. As hackers develop sophisticated techniques to disguise how ransomware appears, it will always behave the same way. Ransomware often starts by scanning IP addresses to find an open port to enter a network. Watchguard firewall will detect and blacklist a scanner.
