Wannacry 2017: the aftermath

Ransomware is one of the fastest-growing types of cyber attacks. After the infamous WannaCry attack in May 2017, ransomware skyrocketed in popularity. However, five years on, where are we now and has the threat landscape changed? 

What Is Ransomware?

Ransomware is a type of malware that locks down your computer and encrypts your files using an advanced algorithm, then demands payment for the decryption key. Ransomware usually comes in the form of an email attachment or link to an infected website (phishing), but it can also be installed through more traditional measures like infected USB drives. 

WannaCry 2017

WannaCry is a ransomware attack that started in May 2017 and infected hundreds of thousands of computers across the world. It made use of a vulnerability in the Windows operating system (OS), allowing it to move from computer to computer without detection by using an exploit developed by the National Security Agency (NSA). When WannaCry was released, most antivirus software failed to detect it because they weren’t updated with security patches Microsoft had released earlier that year. 

The aftermath of WannaCry left many businesses scrambling for solutions against this new form of cyber attack. As a result, the popularity of ransomware as a search term surged. Take a look at this Google Trends screenshot for proof. However, once the dust settled, you can see that the trend of searches resumed and has been steadily increasing since.

Changing Perceptions

Any time we hear about cyber attacks, one thing is for certain: people are going to be concerned about whether their data is safe. The misconception is usually that larger organisations are at a higher risk because their information may be more valuable. However, this is far from accurate as often the smaller organisations lack the adequate security measures to defend themselves against this risk, and as such are easy targets for a cyber attack. Ultimately, the malicious actors aren’t interested in the information, they are more interested in making sure you can’t access your data anymore to force you to pay the ransom. No matter how small the organisation, if you can’t access your own data, you’re at risk of losing your business and that’s what the malicious actors prey on. The fact that search term queries have not continued to grow at the same rate as the number of attacks shows that there’s still a lot of work needed to raise awareness. 

In addition, many businesses don’t know how they would react in the face of an attack, a dilemma discussed by Christian Goelz in his recent article, ‘Ransomware: To Pay or Not To Pay?’. 

While awareness is slowly increasing, there is still a lot more work to be done so that everyone is aware of their risk and can reduce their exposure. Awareness is one of the most effective ways to achieve this and protecting yourself from an attack is not as complex or expensive as you may think. 

Steps to Protection

Sophisticated attacks are difficult to avoid without 24/7 SOC/MDR monitoring. However, there are some simple steps you can take to reduce your risk and protect your business from basic attacks, including: 

  • Updating your OS and apps. It is best to enable automatic updates for everything and ensure that all software is up to date, not just on your laptops or PCs but also on your firewalls and servers. 
  • Password security. Avoid all of the commonly breached passwords and do not use the same password multiple times. You will have probably heard this before and for good reason, these steps are simple, yet extremely effective. We have curated some guidance here on this.  
  • Use two-factor authentication wherever possible (most major services offer this option). It is easy to set up and very effective in protecting you from unauthorised access. 
  • Do not use public WiFi and instead opt for VPNs when accessing insecure WiFi connections (such as coffee shops or airports). 

Cyber criminals are continually modifying their strategies to stay one step ahead of protective systems; it is a true game of “cat and mouse.” To minimise financial and reputational harm, it is essential for organisations to understand how to protect themselves from these attacks and how to recover if they fall victim. In addition to protective measures, always make sure that you have reliable (offline) backups in place and regularly test your data recovery from the backups.
