Malware Warning - Global Ransomware Attack

Global Malware Warning

A new Ransomware Malware has hit organisations worldwide. It appears to have taken down hospitals and other major companies in the UK.

So far this virus has not targeted Australia, but even still we have seen it in Townsville. Now is the time to reinforce good email security policy with your staff, and to check your anti-virus definitions are up to date. In addition you can help shield yourself from this virus by making sure your Windows is up to date.

Ransomware is a particularly nasty virus which encrypts all of the accessible data on your computers and networks. You are then asked to pay a sum to receive a password to unlock these files. The ransom amount is usually far beyond reasonable.

There are a few things you can do to protect yourself:

  1. Ensure your anti virus definitions are up to date
  2. Ensure your anti malware definitions are up to date
  3. Make sure Windows is up to date
  4. Test your backups

Media Releases and Further Information

Microsoft has released the following statement in a blog related to this ransomware:

Today many of our customers around the world and the critical systems they depend on were victims of malicious “WannaCrypt” software. Seeing businesses and individuals affected by cyberattacks, such as the ones reported today, was painful. Microsoft worked throughout the day to ensure we understood the attack and were taking all possible actions to protect our customers. This blog spells out the steps every individual and business should take to stay protected. Additionally, we are taking the highly unusual step of providing a security update for all customers to protect Windows platforms that are in custom support only, including Windows XP, Windows 8, and Windows Server 2003. Customers running Windows 10 were not targeted by the attack today.

How Cloud Based backup can give you better Data Security

Backing up to the cloud has always been an interesting subject, clients not sure that they want their data stored in some remote server, the added cost of data transfer over slow internet connections, high ongoing cost.

Then there are the benefits, with faster internet connections (NBN) high speed and fast backups, no need to remember to take the backup off site or to change the backup device, and not the real kicker, security from the latest crypto locker/ransomware variants, the cost is now much more attractive too.

Yes, by backing up to a remote service you could well be protecting yourselves against a ransomware attack.

The latest variant of crypto locker not only encrypts your data but turns of any local images and wipes attached backup devices and any network storage or other devices it can gain access to.

So if you have looked at backing up to the cloud before maybe it’s time to look again, if you haven’t maybe you should be looking now.

Cloud Backup should be part of your Business Disaster Recovery Plan.

If you would like to discuss your options give us a call.

How to avoid getting Ransomware (CryptoLocker – CryptoWall)

So Ransomware as it implies holds your data to ransom having first encrypted it, dependant on the variant it may also have encrypted any attached USB drive and network attached storage that it can access.
Now if that sounds scary, it should, more than 650,000 PC’s and over 5.25 billion files have been infected in the last 3 years and in 2015 in the USA alone well in excess of $325 million was extorted by this method.
So how to defend yourself.
Ensure that you have good anti-virus and anti-malware protection, it doesn’t cot the earth.
Restrict user network access to only what they need.
Manage network traffic and access points.
Backup everything and ensure that you have a copy of your backup that is not connected to your network.
Have a Business Disaster Recovery or Business Continuity plan so if the worst happens you are prepared.

Speak to you IT service provider and work with them to help ensure you are safe.

How Organised Are Your Network's Shared Files?

A fairly universal experience of office workers is the dreaded feeling you get when you can’t find a file. Whether it’s a word processing document, an image, scanned data, or a different type of digital file, odds are that you’ve experienced the time-consuming and aggravating task of not being able to find the data you’re looking for in your business’ shared network. Panic and, ultimately, frustration set in as you have to pull coworkers away from their tasks to help locate the file—or worse—you begin to recreate it.

So, what can you do to bypass all of the undue stress that comes with an unruly digital filing system?

The first step is to determine and standardize filing labels throughout your organisation. For example, name your document “ABC Company Invoice 30.5.16” instead of “ABC” or simply “30.5.16,” because descriptive labeling will help users locate the file later. Maintaining standardised folders and subfolders—logically arranged and implemented by your entire staff—can also be incredibly useful when organizing and maintaining a network’s shared files.

However, for most businesses, it can be difficult to enforce standardization rules or to retroactively apply them to thousands of existing files. Luckily, a much more reliable and accurate solution for the uniform naming and storing of digital documents is by implementing a Document Management System (DMS) to keep your business data organized.

DMS software will name, index, and store your documents using a standardized system, without having to rely on each employee to remember and consistently apply the agreed-upon naming convention. Each file name will also include the date that the document was originally created and track dates of all modifications to that file.

DMS also authorizes you to search in a variety of ways, which allows you to find documents faster than you could with standard searches. For example, if you’re replicating an event from last May, with DMS you can search for a date range, the event’s name, or even the author of the document. Another useful search tool with DMS is the ability to search the actual contents of all of the documents in your shared system via keywords. Not unlike a Google search, you can even use words like “and” or “or” to add or subtract distinct phrases and keywords while searching through your system’s files.

Sophisticated DMS technology not only helps you quickly locate the exact files needed on your network, but also can track and limit viewing, editing, or deleting capabilities based on specific users. This security feature protects your business, customers, and employees’ confidential data.

In addition to its long list of additional capabilities—like workflow automation, email integration, and document recovery solutions—the first step is to organize your shared network by implementing the automated filing rules offered by DMS software. Once put into effect, your next file search will be fast, instead of frustrating.
