No doubt you’ve read the recent news that NHS services across England have been hit by a large-scale cyber-attack and they have elected to protect their IT systems by shutting them down as a precaution.
One point to note from this is that the attack was not specifically targeted at the NHS and is affecting organisations across a range of sectors. The ransomware spread is agnostic – it is not bothered by size or value (the ransom request itself is only reported to be £230), small businesses to large enterprises are being hit. It is widely reported that over 100 countries have been hit by the “WannaCry” ransomware.
What does this mean to you and what are we doing about it?
We are running two types of Anti-Virus and Anti-Malware on our managed networks. You have either BitDefender or Sophos deployed as part of your defence.
Both products have automatically deployed security patches against the attack, however, if your anti-virus application is showing a red cross, or is greyed out you could possibly not be protected. If you suspect your protection is turned off or not updating, please call us immediately.
Microsoft released a security patch on 15th March to fix a flaw that was in the Windows Server Message Block (SMB) service, which Windows computers use to share files and printers across local networks. Microsoft addressed the issue in its MS17-010 bulletin.
We are currently checking all our customer’s networks to ensure that the necessary patches are in place.
