Cybersecurity threats that have impacted businesses in 2019

Cyber Security

Cybersecurity is a hot topic for businesses and one that needs to be taken seriously. From zero-day exploits to known vulnerabilities there are a huge range of security risks that businesses need to be aware of. With hackers and malware becoming more and more sophisticated cyber threats are something that businesses can’t afford to ignore. In this blog, we’ll take a look at some of the biggest cybersecurity threats in 2019 and what you can do to combat them.


Phishing is one of the most common forms of cyber threat and one that is extremely costly. A phishing attack focuses on eliciting sensitive information from employees most commonly through email or social media sites. Clicking on links will lead the employee to provide sensitive information or company data which can then be used by cybercriminals to gain access to secure networks, access financial information and steal data.

As phishing targets employees one of the best defences is to implement cybersecurity awareness training for staff and emphasise the importance of reporting phishing. Email and spam filters can help stop phishing emails while mail encryption and email signing certificates can help improve email security.


Easy to spread and hard to detect, malware is a huge threat for businesses and one that can cause big problems. Adaptive malware can change its coding with each new iteration making them extremely hard to prevent. Malware is commonly downloaded by users unknowingly as part of a phishing scam or when visiting compromised websites. Backdoors, downloaders, trojans, worms and macro viruses are all types of malware.

To help protect your business against malware you should use reputable antivirus and anti-malware software, endpoint security and email spam filters. Limiting user access and privileges can also help to prevent employees from installing malware and unsafe applications.


If you operate an online e-commerce store, then you need to be aware of formjacking. Cybercriminals target online stores and exploit vulnerabilities in payment forms to inject malicious JavaScript on checkout forms. These are serious issues which can result in the loss of financial information and personal details. British Airways is one of the best examples of a formjacking attack with a hacker stealing 380,000 credit card details and stealing £13 million from consumers.

Vulnerability testing and scanning will help to identify any weaknesses in your cybersecurity while monitoring outbound website traffic can help you identify if traffic is being sent to destinations it shouldn’t be. SRI tags can help to ensure that your web files don’t contain manipulated content.

Patch management

Patches are an important part of keeping operating systems, servers and software up to date. Manufacturers release regular patches to keep their systems and software up to date and to help prevent vulnerabilities. If you fail to implement the latest patches then your business will be at risk of cyberattacks which could cause downtime, data loss and reputational harm. Outdated software and end-of-life operating systems could all give hackers easy access to your IT systems and cause real security threats for your business.

To help ensure your systems are secure you should be installing patches as soon as they are released by the manufacturers. For most small businesses this is extremely difficult which is where a managed IT service can help.
