In response the the major cyber attack that has targeted the NHS and other business across the UK last week, Microsoft has released a critical update for all operating systems including those no longer supported such as Windows XP, Windows Vista and Windows Server 2003. Microsoft has urged all Windows users to apply the MS17-010 hotfix update as soon as possible.

This update has been released through Windows Defender. More information about the hotfix may found on the Microsoft Technet website.

For most personal and small business customers, install this hotfix and any other outstanding updates via Windows Update. In Windows 10 or Windows Server 2016, the update should be automatically installed. If not, access Update via Start > Settings > Update

What is WannaCrypt and how does it work?

The ransomware known as WannaCrypt has taken advantage of a security vulnerability within Windows that present in at least 200,000 computers in more than 150 countries worldwide. Once a computer is infected, all of its' files are encrypted by the ransomware which then demands payment from the user to access their files. If payment is not received by a certain date, then it is potentially lost forever.

Once installed, WannaCrypt acts like a worm and replicates throughout the local network infecting any other vulnerable computers.

This vulnerability came to light in March and Microsoft issued a patch for all supported Windows systems. WannaCrypt has taken advantage of computers that are either running older, unsupported versions of Windows (Windows XP, Windows Vista and Windows Server 2003) or those that have not had the patch installed.

Email Scanning

Although we scan all email messages that pass through our servers, we cannot guarantee all infected files are intercepted and deleted. We urge all our customers to ensure they are protected against ransomware, viruses and other malware attacks by ensuring they have an up-to-date security software installed on all computers.

When a website falls over the cause may typically traced to either bad coding, the web server, database or just plain old human failure. LeafURL stopped working at around 19:30 yesterday for an odd and unexpected cause. The AntiVirus software suddenly and falsely considered our CalzadaMedia.Web code library to be a virus.

As its' name suggests, CalzadaMedia.Web is entirely written by us and it is used in many websites we have built. It provides common functionality and controls that are required in most ASP.Net websites. It's just one of many code libraries we have created to make life simpler. Instead of copying code from one project to the next, we just use the library.

The really strange thing here is that the exact same version of the library is in use by other websites on the same server and they weren't identified as being viruses. The AntiVirus software has had a good talking to and this problem shouldn't (crossed fingers) raise its' head again.

As we frequently use shortened Urls, some users may have experienced a few problems whilst LeafURL was offline. Our apologies to anyone that was affected.

We have recently revised and updated the anti-virus and anti-malware scanning that we perform on all incoming messages for our standard mail accounts.

As before, any message (including attachments) that is detected as containing a virus or malware will automatically and irrevocably be deleted. This entire process occurs before the offending message is delivered to the recipient's inbox.

If a virus or malware is detected, our mail servers will also send a notification message to the intended recipient. This notification includes key information like the sender's address and the message's subject. As many infected messages may also be considered to be spam, the notification message may end up in your mailbox's SPAM folder.

As we cannot guarantee that our antivirus scanners will intercept every infected message, we strongly urge all of customers to install antivirus software on their PCs. There are a substantial range of antivirus/security software providers - AVG, Avast, Eset, Mcafee to name but a few - many of whom offer a free* versions of their antivirus products.

* Software licence conditions and limitations will vary - please check with supplier.
