Are you aware of ransomware?

Ransomware is just one of many cyber-threats that a business faces. Even before the switch to remote working due to the Coronavirus pandemic, Ransomware was a significant cyber-hazard. However, in recent weeks the problem has only gotten worse, with ransomware attacks proliferating both in number and severity.

Recently, the US-based IT services provider Cognizant admitted that the ransomware attack it suffered in April 2020 could result in the company losing as much as $70m. However, the threats are just as real closer to home and we are also aware of a growth spike in this particularly nasty type of attack amongst SMEs locally.

As we all adapt to the ‘new normal’ ways of working, at Blue Rock we continue to promote advice that businesses should maintain or strengthen their cyber security policies during this time as an ongoing priority to best protect their sensitive data.

Like other forms of cyber-crime, Ransomware poses a more dangerous threat to businesses which aren’t sufficiently equipped with the awareness, know-how and tools to defend themselves. That is why in today’s blog we are happy to tell you more about ransomware and give some advice on how your business can avoid its harmful effects.

So, what is ransomware?

Ransomware involves users being tricked into installing malicious software which restricts access to a computer system and/or files until a ransom is paid. Ransomware works in one of two ways, i.e. ‘crypto’ ransomware encrypts a user’s files/data, whilst ‘locker’ ransomware locks a user out of their system entirely.

Ransomware attacks you may have heard about include WannaCry, RobbinHood, Ryuk, Bad Rabbit and CryptoLocker, which have infected hundreds of thousands of computers and caused vast amounts of damage.

Over time, cyber-crooks have adopted more advanced techniques whilst learning from past mistakes. For instance, as businesses have reacted by diligently backing up their data – therefore negating the need to pay ransom amounts to regain access to it – hackers have responded by threatening to leak the private data they have captured (from secret recipes to financial records) if businesses don’t pay up.

What ways can a business fall victim to ransomware?

There are many different ways businesses can fall victim to ransomware and not all of the methods involve a user clicking on a malicious link or attachment. For example, “Brute force” attacks involve hackers exploiting password weaknesses to hack into systems and seize control of data files. Whereas “Drive by” downloads involve the malware being installed simply by a user visiting a compromised website.

Phishing and spear-phishing e-mails can be very effective at enticing users to click where they shouldn’t, whilst there is the ever present danger of ransomware being installed via infected USB sticks and other portable media.

What are the effects of a ransomware attack?

To put the monetary implications into context, the ongoing crisis has only catalysed cyber-criminals’ operations and the projected financial impact across the globe is alarming, with it being estimated that the cost of ransomware could grow to $20bn US dollars (£16.3 billion) by the end of 2021. (You can read more of the article which predicts this here.)

Whilst the severity of individual attacks can vary in terms of the ransom amounts being demanded, there are other detrimental effects to consider. Certainly, ransomware attacks cause significant disruption and downtime. Theft of personal data puts customers and staff at increased risk of cyber-crime and the negative PR associated with a data loss can destroy a carefully built reputation. In a leakware scenario, the damage can extend to the theft and the subsequent sale or publication of a company’s Intellectual Property, which can be catastrophic.

So, how do I best avoid the dangers of ransomware?

Depending on your circumstances, the best approach for your business is likely to be multi-faceted. This could include implementing correct data governance procedures and introducing IT security solutions which monitor your systems for suspicious activity, as well as education and training to empower your employees with essential knowledge. There are various strands to each area, as you can see in the infographic below.

What about cyber insurance?

Cyber insurance is a relatively new type of insurance which is intended to protect businesses from internet-based risks and financial losses caused by data theft, fraud, hacking, extortion and other criminal activity. Premiums can be steep and will depend on the amount of cover you need.

Like other forms of insurance, the underwriters will assess how big a risk it is to provide you with cover. That means businesses without good information governance protocols in place may find it difficult to get coverage for this type of insurance. On the other hand, businesses with robust cyber-defence measures in place will attract lower premiums.

How can NVT Group & Blue Rock help?

At Blue Rock, we can help you implement information governance protocols in your business, so that you can stay in control of your data, keep it best protected and remain compliant with data protection regulations.

We actively work with you so that there is consistent and proper handling of data across your organisation. This is achieved by setting up data protection processes, empowering people with knowledge and using technology to help make adherence to processes easier.

A good place to start is to undergo an audit with Blue Rock. We can perform an assessment of your entire cyber security stance and uncover hidden risks, highlight gaps and discover weaknesses. This is followed by recommendations and methods to improve your cyber defence position.

These could involve activities such as cyber awareness training for your employees, using ethical ‘white hat’ hacking techniques to uncover password weaknesses and ongoing spot checking to ensure continued compliance across your business.

Since Blue Rock is an NVT Group company, we can also make recommendations on which technology solutions can protect you, such as Concepta Security Services. If you need advice on data storage, backup and disaster recovery strategy, we can assist with this too.

Ultimately, our priority to find out where your threats lie, fix these and help you defend yourself in the future. We can offer an initial cyber audit to identify any weak spots before implementing proven solutions to keep you protected.

To discuss your cyber audit, please contact us at or call us on 0345 369 0103.
