Today there has been a global ransomware virus outbreak on a scale never seen before. This outbreak has hit hundreds of thousands of systems and has caused IT shutdowns across the NHS, Santander, Fedex, KPMG, German railway operators and Russian mobile phone networks to name a few.
This is not a targeted attack. The Ransomware is infecting any Microsoft Windows systems (that are accessible from the internet) which have not been patched against a vulnerability discovered at the end of March 17 (https://technet.microsoft.com/en-us/library/security/ms17-010.aspx) . The vulnerability in question was being used by intelligence agencies in the USA as part of their cyber program but it was then obtained by a hacking group and released into the wild hence it now being widely exploited to spread this ransomware.
Throughout the course of the evening we have been conducting a security audit across all client machines that are accessible from the internet. You may have noticed some interruptions to your services whilst we tweaked configurations on your systems to ensure that our defences against this huge attack stand firm. Please accept my apologies for this, however due to the significance of today’s events we had to act immediately without issuing a maintenance notice.
Due to the design of our systems and processes we have not seen a single infection at any of our clients.
We will continue to monitor this outbreak as it unfolds. I have included a link to the BBC coverage on this story should you wish to read further.
