You may have noticed over the weekend on the news that there is a huge cyber-attack currently happening across the world.
This has affected the NHS systems as well as Fedex and many other businesses, both large and small.
The attack has been gaining ground rapidly after starting on Friday. It is based on ransomware and being called WannaCry. If you are infected, you will see your files beginning to be encrypted and the software will demand a ransom to be paid to “gain access to your files”. There is no guarantee that you will get your files back, even if a ransom is paid.
WannaCry is working on a known vulnerability that Microsoft announced in December / January. This vulnerability was fixed with the release of a software update (patch) earlier this year. This patch is on the automatic update run from Microsoft Updates.
To mitigate this attack we have been working tirelessly over the weekend checking and rechecking all of the servers we look after to make sure they are fully patched and up to date. As part of our update routines, we can confirm that the servers were all fully patched and up to date, meaning the vulnerability hole had already been filled on the servers we look after.
Today we are contacting all our support customers to double check all PCs are also filled and patched. We are confident that all our PCs will be covered as part of our proactive maintenance, but we are performing due diligence with all devices we look after.
Our main Anti-Virus partner Webroot has announced that their software is actively blocking the attack if Webroot is up to date on your devices.
As we are writing this, Malwarebytes has also confirmed that paid subscriptions of their anti malware software is actively blocking the Ransomware.
If you are worried about the attack, please follow the advice below –
To run Windows Updates, go to Start > Control Panel > Windows Updates > Update Now. Once the scan for updates has finished, install all important updates listed. Restart your machine when asked and this should fill the hole.
Most Anti-Virus companies have released patches and definitions to help combat the attack. Open up your AntiVirus software and perform an update to it if it hasn’t run through automatically
If you have a USB drive, then back up your recent and important data to this. Keep it away from your PC and update the drive periodically to ensure you have the latest versions available to you. If you want to discuss more regarding backups, we provide a wide range of options from USB devices to cloud backups.
