Global Ransomware Prevention

On Friday May 12, 2017, a new wave of ransomware known as “WannaCry” (detected by ESET as Win32/Filecoder.WannaCryptor.D) spread across the globe and infected tens of thousands of computers. This ransomware propagates by exploiting a Microsoft Windows vulnerability in unpatched computers.

ESET detects and blocks the WannaCryptor.D threat and its variants. With ESET’s network protection module, we are blocking the leaked version of the exploit on the network level.

We have issued an alert on our Knowledge Base site providing step-by-step instructions for our customers to ensure they are protected. This can be accessed via the following link:

Our introduction to the Synology NAS

You need to read this if you have several gadgets spread across your home, like smartphones, laptops, intelligent sound systems, Smart TVs and more. With your devices situated in your bedroom, front room, and across the house, are you looking for a device that can keep all your photos, films, songs and files from your gadgets in one location that is safe, easy-to-use and readily accessible?

Sharing photos and movies

With thousands of files stored across all your gadgets, finding specific photos, documents and videos can become a real headache. With a Synology NAS, however, you could consolidate all of these files in one location. Simply upload all the files and each device connected to the NAS and this works without a glitch. Once it was done, you will be able to find exactly what you needed in seconds. No more frustrating searches across all your devices and drives. A click on an app, and there are your photos. You could even tag them like Facebook, search by location or share them online publicly or privately.

Safe and Secure

Now you have all your files in one place, you should be concerned about what would happen if your NAS was damaged or your hard drives failed. No need to worry.. with Synology, you can setup RAID (Redundant Array of Independent Disks) very easily. Enabling RAID means you can save to your NAS as usual and if a drive failed, you would have a backup already stored. Also, if you needed to replace any of the drives in your NAS, you can simply restore data as if nothing happened.

Much more than a NAS

The more you use your NAS, the more you will wonder how you ever managed without it. Sharing photos and movies with friends and family, or sharing files with colleagues at work was simplicity itself. And you can do it from anywhere there is an Internet/WiFi connection, even over 4G with your smart phone.

Your Synology NAS is full of surprises, going way beyond what you expect from NAS drives. With the free apps, you are able to use it as a home server, streaming all the content from your GoPro, as well as the movies and TV shows you have stored, straight to your Smart TV. When friends and family stay over, you can even stream movies, or music, to different rooms of the house... all from this one NAS.

Social Engineering Scam

Social Engineering

If you get an email or phone call claiming to be from your bank or credit card provider, a government department, a membership organisation, a website you buy from or the police – and it’s asking for confidential information – chances are it’s social engineering and is not legitimate.

If you get an unexpected phone call from a computer company or engineer telling you that you have a problem on your PC and offering to fix it, chances are that’s social engineering too.

Social engineering is the name we give to confidence trickery, because the criminals who perpetrate it have very clever and convincing ways to deceive you.

To find out how to spot social engineering and how to deal with it, have a look at the videos on this page. They describe three common types of social engineering, but there are many more.

Windows 10 - March Update

Microsoft has been ever increasingly aggressive in its attempts to push consumers to download Windows 10. Starting recently, the company is upping the ante once again. As of now, Windows 10 is now classified as a “Recommended” update, which means many Windows 7 and 8.1 users will download and begin the installation automatically.

The upgrade process is less problematic now, some users have managed to upgrade with no problems. But there still remains a small risk if upgrading, we can normally sort out any problems for you.

By default, Windows 7, 8, and 8.1 shipped with updates enabled and a second box — “Give me Recommended updates the same way I receive important updates” checked as well. Plenty of users have changed these settings, but you can bet millions of people haven’t. 

Microsoft has stressed that end users who begin the upgrade process will still have the option to say “No” before the upgrade begins, but we're dubious of this for several reasons:

First, we’ve already seen what Microsoft’s version of “No” looks like — it looks like this:

Microsoft have made it nearly impossible to NOT upgrade to Windows 10. The company’s opt-out for Windows 10 installation is unlikely to be much better. Even if it is, however, there’s still a larger issue — specifically, the people this upgrade is going to hit are those who are the least likely to know it’s coming.

There’s no way this doesn’t create headaches for at least some Windows users, as well as Microsoft. Some drivers still won’t update properly if you upgrade to Windows 10. Some people will misinterpret the installation as malware, since Microsoft hasn’t historically updated its operating systems in this fashion. Some will click on “Get Windows 10″ without realizing that it’s an entirely new operating system that makes massive changes to how basic system functions work and look. 

All of these issues are issues with any system upgrade upgrade, but OS updates are typically something the user initiates and wants. Microsoft clearly wants its entire user base on Windows 10. But think about this: This move targets users who don’t know enough to disable Recommended updates, but have also rejected Microsoft’s previous offers. This could create a nasty snarl of blowback if the upgrade push starts making life difficult for large numbers of people.

Microsoft has published a KB article detailing how end-users can control the upgrade prompts and disable them in the future, available here.

We are still advising customers to only upgrade if they have newer computers and have taken a full backup before they start the process. Sometimes it is possible to downgrade back to your old OS, but a lot of the time it is not, so think twice before upgrading.
