Cyber attacks have been a huge issue for a number of years now, since the mass adoption of internet technology. However, in recent years concerns have expanded to include a specific and very serious type of attack ‘ransomware‘. Investing in strong antivirus and firewall solutions is a good start, but businesses need to be prepared for the day that their defenses fail from a ransomware attack. With ransomware affecting millions of businesses worldwide, it is vital to know how to protect your business from being vulnerable to further attacks.

Ransomware attacks tend to be delivered via email or through a illegitimate link on a website. As soon as the email document or link is clicked the ransomware is downloaded to the system, and typically begins to automatically run commands and install infected files. So how can you protect your business against ransomware?

Protecting your business

Email & Web Filtering

The first line of defense is to prevent threats from actually making it to your mailbox in the first place. With the use of advanced email filtering, we can block emails and scan for attachments and links to eliminate potential threats. Keep receiving spam emails from a specific sender? We can assign them to your mailbox blacklist so you never receive emails from them again. Likewise, ourĀ web protection goes beyond enterprise antivirus software and firewalls by letting you set your own content-filtering policies, website blacklists, time- and content-based browsing policies, and much more.

Software Updates

Software providers are constantly updating and resolving bugs and errors within their products, to ensure that cyber attackers don’t gain access to their system. As tempting as it may be to ignore or cancel an update, having the most up-to-date application will give you the best chance of preventing hackers.

Data Backup

With all cyber threats there is no guarantee of 100% security. If there was ever an event in which your business network was attacked with ransomware, our backup solution can provide the last line of defense to quickly recover business data and necessary information needed to function the business.

Understand where data is stored

It’s important to understand where you business data is stored, and how it is managed to maximize the effectiveness of response within a disaster. Being able to locate damaged business data quickly is vital, as it will help improve the chance of losing further important data.

Educate employees

Ensure your employees are well educated about how to stay safe online. They should be informed to exercise caution when opening emails, clicking on links/websites and downloading software. Likewise, they should be able to determine common warning signs and be able to raise the alarm within the company.

5 Biggest Ransomware Attacks

CryptoLocker

CryptoLocker was one of the first forms of ransomware that came onto the scene in 2013 on a global scale. CryptoLocker was distributed through spam messages and used RSA public key encryption to seal up user files and demand cash in return for decryption keys.

Within a year a new threat arose, called TeslaCrypt. It targeted video games and downloadable content which are precious files to gamers, and are usually stored in the cloud. By 2016, TeslaCrypt made up 48% of ransomware attacks globally.

SimpleLocker Android

SimpleLocker is known to be the ‘Android-based attack’ and in late 2015 early 2016, it encrypted users files and made them inaccessible without the scammers help. SimpleLocker was also the first known ransomware that delivered its malicious payload using a Trojan downloader, which made it much more difficult for security measures to catch up to.

Wana Decryptor

WannaCry made its mark in 2017 and was one of, if not the biggest ransomware attack that has ever occurred. Shutting down hospitals in Ukraine and Radio stations in California, WannaCry became a global threat and made people realise how serious ransomware was and the affects it could have on everyday life.

NotPetya

Just weeks after the WannaCry outbreak, an updated version named “NotPetya” began to spread and it used the same code package that WannaCry had used. It was a more advanced version and has said to cost companies $1.2 billion in revenue.
