New Ransomware Attacks With JavaScript

A newly discovered ransomware does away with downloading a malicious file, carrying out the encryption itself


A new form of ransomware has emerged that tries to evade detection by carrying out all its encryption using the JavaScript scripting language.

This the latest in the rapidly expanding ransomware category, which has grown into a significant threat in recent months as criminals are attracted by lucrative payouts.

“The JavaScript doesn’t download the ransomware, it is the ransomware,” wrote Sophos researcher Paul Ducklin in an advisory. “No additional software is downloaded, so once the JS/Ransom-DDL malware file is inside your network, it’s ready to scramble your data and pop up a ransom message all on its own.”

The script arrives as an attachment called Invoice.txt.js, which appears as “invoice.txt” on most Windows systems, which are configured by default not to display file extensions.

If opened, JavaScript attachments of this kind execute by default in the Windows Script Host (WSH), which doesn’t impose any restrictions.

The new technique is simpler than the most common method of infection, which involves the use of a Word document which then downloads executable code from a remote server.

Superfast Broadband for Cumbria

Superfast, fibre broadband (FTTC) has been available for a while and most businesses who can get fibre have already taken advantage of the faster download and upload speeds it provides.  But some businesses have felt a little left out because Fibre broadband isn’t available to all!  Those close to the telephone exchange (EO lines) and some in more remote areas who don’t have a cabinet to connect to cannot get fibre broadband and have to make do with slow ADSL speeds.

But things are slowing changing with the help of Connecting Cumbria.  They are working with BT to enable as many cabinets as they can and install new cabinets for the exchange only lines.  Kendal has seen a number of cabinets pop up in the last few weeks helping businesses in the centre of town get superfast broadband.  This project is going on all over Cumbria and they hope to bring fibre broadband to as many people as possible.

If you want to check if fibre broadband is available to your business, you can use BT’s DSL checker.  If you want some ideas on how your business can utilise a faster broadband connection, just give us a call on 01539 720104

Should You Try An Online Backup Solution?

backupYou have lots of options when it comes to backing up your data.  Tape drives, NAS devices, USB drives and of course cloud-based backup.  One of the most common questions we get asked about backing up is should we be using an online backup service?

What are online/cloud backups?

Generally speaking, an online backup features a storage system where a copy of all your files and even systems is kept on a remote server online and are only accessible through an internet connection. Backing data to the cloud gives you some level of security and if something were to happen to your data, you can easily access them and restore your system so long as you have an internet connection (the faster the better!).

Advantages of online backups

Online storage and backup data can be accessed from any computer, so you can reach your files even if your computer is lost or stolen. You can also access your files from other computers while you are traveling, even if you forgot to bring those files with you. Automated services that back up all files on your computer at preset times are also useful because you data is protected without requiring that you remember to run a manual backup or connect the computer to a hard drive. Good backup and storage services have redundant systems so that even if one of their storage facilities is damaged, your data will be safe, unlike a single physical backup device.

Disadvantages of online backups

Data on the Internet can be accessed by hackers if the security is not high. This is also true of any data on your computer when it is connected to the Internet, but physical backup discs can’t be accessed remotely. Online backup services may also charge monthly or annual fees, which over time can add up to much more than the cost of a physical backup device. To successfully use online backup or storage, you must remember your password and user identity to access your materials. Otherwise, your backups will be inaccessible unless the program you use has the ability to verify your identity and reset your access codes.
Your internet connection speed is the biggest limiting factor, if you broadband is slow forget online backups.
