    We’re aware that over the past few weeks, there has been an increase in CryptoLocker-style attacks. We want to make sure that all of our customers are aware of the situation and provide them with a few tips on how best to be prepared to combat this.

    What is CryptoLocker?
    CryptoLocker is a ransomware trojan that targets computers running Microsoft Windows. Created via infected email attachments and via an existing botnet, when activated, the malware encrypts certain types of files stored on local and mounted network drives using RSA public-key cryptography, with the private key stored only on the malware’s control servers.

    The malware then displays a message which offers to decrypt the data if a payment (through either bitcoin or a pre-paid cash voucher) is made by a stated deadline, and threatens to delete the private key if the deadline passes.

    If the deadline is not met, there is a second message supplied stating that the price to decrypt is now much higher.

    Although the CryptoLocker is readily removed, the files that it encrypted remain that way in which is considered unfeasible to break. It is said that the ransom should not be paid, but there aren’t many solutions to recover the files if payment is considered, some victims have claimed that paying the ransom did not always lead to the files being decrypted.

    How to protect yourself
    The best way to stay secure is to have the latest security solution. If you have Fortinet Sandboxing, this will go a long way to protect you from CryptoLocker. Additionally, you should:

    • Backup regularly and keep a recent backup copy off-site
    • Enable file extensions
    • Open JavaScript (.js) files in Notepad
    • Don’t enable macros in document attachments received via email
    • Be cautious about unsolicited attachments
    • Don’t give yourself more login power than you need
    • Stay up-to-date with new security features in your business applications.


    We can help with FortiSandbox

    FortiSandbox, provided by Fortinet, offers a robust combination of proactive detection and mitigation, threat insight and integrated automated deployment. At its foundation, it’s a unique, dual-level sandbox which is complemented by Fortinet’s award-winning anti-malware and optional threat intelligence. Years of Fortinet threat expertise is now packaged up and available on site or via the cloud via FortiSandbox.


    When FortiSandbox discovers suspicious codes, these are subjected to multi-layer pre-filters prior to execution in their virtual OS for detailed, behavioural analysis. The highly effective pre-filters include a screen by Fortinet’s AV engine that sends queries to cloud-based threat databases and OS-independent simulations.


    Once a malicious code is detected, granular ratings along with key threats is measured, a signature is dynamically created for distribution to integrated products and a full threat information is optionally shared with FortiGuard labs for the update of the global threat databases, making sure that you’re as safe as possible.


    If you’re unsure about CryptoLocker or Ransomware as a whole, please contact us and we’ll discuss it with you in detail, how your infrastructure is set up to protect yourself from the threats today and in the future.

    ” I would like to take this opportunity to thank you for all the prompt assistance you provided us with during this project.

    ” Being responsible for IT in an organisation which is very tech dependant is a real challenge, especially having no formal IT experience myself.  Having the Nouveau team at the end of the phone is a real-life saver and I have needed a life line many times.  I most appreciate the accessibility, knowledge and friendliness of the team. “

    ” The company I work for has been using Nouveau Solutions for the past 15+ years and I have had the pleasure myself to build up a good, close relationship with them for about 12 of those years.

    Nouveau Solutions have dedicated teams for each different area that are made up of very knowledgeable technicians and engineers that specialise in their specific area of expertise. It is due to this that I always feel confident that Nouveau Solutions will be able to deliver us any IT services that we may request from them (there has been a lot over the years).

    They have always gone above and beyond to deliver high quality professional IT services to meet any requirements that we throw at them within any timeframes that we may set.

    On top of the ad-hoc IT services we request from Nouveau Solutions, they also monitor, manage, maintain and support some of our network infrastructure and have always been on hand to resolve any issues that may be noticed via their monitoring or raised by us within a timely manner.

    We also purchase the majority of our IT equipment including hardware, software and licensing through Nouveau Solutions which is always at a reasonable price and always received within a timely manner.

    Since day one of our relationship with Nouveau Solutions we have been appointed to the same one account manager which has allowed him to get to know our business very well. The service that has been provided by him to us has been nothing but exceptional. He always comes across as knowledgeable in any business discussions that we may have and has always been happy to take the time to communicate with us, make us aware of anything that we need to be aware of, or provide us with updates on anything.  I have always had the impression that his main priority is to ensure that we are happy with everything that Nouveau Solutions provides to us and he will do anything to ensure that is the case.

    All in all, I have nothing but praise to offer for Nouveau Solutions and would highly recommend them to any company that was looking for an IT services company.  There are definitely no plans here to switch to a different IT services company for the foreseeable future.

    Here’s to many more years with using Nouveau Solutions! “

    ” Nouveau have been brilliant from start to finish – very professional and competitive with their service and pricing. We needed a large number of Firewalls to deploy across our global company over a very short time period and thanks to Jack’s excellent availability, Nouveau’s turn-around time was extremely swift, even with nearly no notice. Nouveau not only provided us with the hardware  – one of their competent technicians supplied us with some design work in the past to help with our data centre firewalls replacement project! Nouveau have been great to work with. “

    Hassan Ashraf | IT Service and Infrastructure Manager | Everlight Radiology


    ” In the summer of 2017, I approached Nouveau in the hope of finding a competent partner that could help us through an upcoming hardware refresh. A priority of ours was to discover a local business (within 20 miles) that excelled and specialised in HPE, Dell, Fortinet and Microsoft/Office 365 as we planned to refresh our whole core infrastructure,. This included storage, infrastructure hosting and networking (core, access and perimeter) for our headquarters and our other branches. After an extensive phase of speccing, detail planning and quoting, Andy Swain and his team were able to offer a “spot on” solution for our demands with a very high cost/value ratio. This project led to a very open and trusting partnership with Nouveau and made them our No.1 partner within IT. “
