SIMS Technical Cautions on Upgrading to Microsoft Windows 10

Microsoft launched Windows 10 on the 29th of July 2015. This is a free upgrade for users who currently operate Window 7  or 8.1.

Windows 10 has plenty of benefits which we have outlined in our blog –  Should I Upgrade to Windows 10?. However, it is still advised that you should think carefully before you upgrade. This means ensuring that you have backed up your data, and you have fully researched the operating system. Specifically, in regards to any SIMS workstations. This is because Capita has provided advice that it will not support Windows 10 until April 2016.

At the moment, Capita plans to support Windows 10 on 64-bit workstations only. So if you are to upgrade or replace PC’s and laptops, you will need to wait for clarity from Capita.

So our recommendation is to not upgrade to Windows 10 as of yet if you are a Capita SIMS user.

If you need any advice, you can contact Coretek!

Virus warning – Cryptolocker virus

We have noticed a recent increase in a particularly nasty form of malware known as the Cryptolockler virus. This is sometimes also known as the CryptoWall virus.

Here’s what happens:

Upon infecting the machine in question, the virus proceeds to encrypt all of the user’s data, including local hard drives and network shares.

Cryptolocker 1

The only way to get the data un-encrypted is to pay a ransom fee and even then, there is no guarantee that this will be honoured.

Cryptolocker 2

This is potentially very damaging as there is the potential for an entire companies data to be lost.

The most common source of this virus is via email. A user will receive an email from a seemingly legitimate company such as eBay or a courier service inviting them to click a link. Upon clicking the link, the virus will be downloaded and will infect the user’s machine. There is also a possibility for this virus to propagate using other channels such as messenger programs and social media.

 

Watch out for the following:
• Do not open any emails from an address you do not recognise. Check the actual email address not just the sender’s name.
• Be very wary of clicking on any links within an email, even if the email is from someone in your address book or from a seemingly legitimate company.

To ensure that you are protected, we recommend the following preventative measures:
• Anti-virus software is fully updated with the latest signatures
• Operating systems, browsers and browser plugins are up to date with the latest security patches

As with any security issue, informing and educating staff is paramount so it’s always a good idea to inform everyone in your company who could be affected.
