Ransomware is one of the most serious threats facing businesses today. This type of harmful software locks your files or systems and demands a ransom to regain access. With more organisations relying on digital tools and remote working, ransomware attacks have become more common and more damaging. From small businesses to large enterprises, no one is immune. But understanding what ransomware is and how you can protect your business is the first step to staying safe.
In this blog, we’ll explain ransomware, its impact, and the different types. We’ll also share practical steps to help your business avoid falling victim to these attacks and keep your valuable data secure. Read on to learn more!
What is Ransomware?
Ransomware is harmful software designed to lock files or systems using encryption. Victims lose access unless they pay a ransom to the attackers. Cybercriminals often gain access to an organisation’s network through methods like phishing emails that trick users into sharing sensitive information, such as passwords. Once inside, they deploy ransomware to lock down multiple systems or even an entire network.
So, what is ransomware, and how can you protect your business? It’s a pressing question for organisations today, given the significant impact ransomware can have on operations, finances, and reputation. Ransomware isn’t a new phenomenon—it dates back to 1989, when a biologist distributed a Trojan via floppy discs under the pretence of sharing information about the AIDS virus. Users were instructed to pay an amount to regain access to their systems.
The rise of ransomware in the late 2010s can be linked to the increasing reliance on digital systems. With society’s heavy dependence on online education, government portals, telehealth services, eCommerce, and remote work, ransomware attacks have become a lucrative way for criminals to earn money or disrupt operations.
2 Different Types of Ransomware
Ransomware is typically categorised into two types:
- Crypto Ransomware: This type encrypts files, making them inaccessible without a decryption key.
- Locker Ransomware: This strain locks the entire system, preventing users from performing basic tasks.
Understanding what ransomware is and how you can protect your business includes recognising these different types of ransomware. Modern ransomware attacks often combine file or system encryption with data theft. This approach, known as double extortion, involves demanding two payments: one to decrypt the files and another to prevent sensitive data from being leaked online.
The rise of ransomware-as-a-service (RaaS) has further expanded the problem. RaaS groups provide ransomware tools to other criminals for a fee or a share of the ransom. This model makes it easier for anyone to carry out an attack without creating their own malicious software.
Who Is at Risk of Ransomware Attacks?
While any business can fall victim to ransomware, certain factors make some organisations more vulnerable:
- Sensitive Data Storage: Businesses holding valuable data are prime targets for attackers seeking large ransoms.
- Low Cybersecurity Maturity: Sectors like transportation, higher education, and oil and gas often have weaker defences, making them more appealing to attackers.
- Small and Medium-Sized Businesses: Cybercriminals perceive smaller companies as having less robust security measures compared to larger organisations.
- Geopolitical Targets: Some ransomware groups are state-sponsored, focusing on causing disruption rather than financial gain.
Why Paying Ransom Is Not the Answer
Experts strongly advise against paying ransoms for several reasons:
- Paying doesn’t guarantee recovery of encrypted files or stolen data.
- It encourages more criminal activity by showing attackers that their tactics work.
- In some jurisdictions, paying a ransom may be illegal, as it can be considered funding criminal operations.
8 Practical Steps to Protect Your Business from Ransomware
There are eight practical steps to protect your business from ransomware.
Continuous Monitoring and Regular Updates
Monitor all potential entry points into your network, such as IP addresses and applications, for unusual activity. Regularly update software, firmware, and operating systems to patch vulnerabilities before they can be exploited.
Educate Employees
Employees are often the weakest link in cybersecurity. Provide engaging and relevant training to help them recognise phishing scams and other threats.
Backup and Recovery Planning
Maintain frequent backups of critical data in secure, offsite locations. Having a backup ensures quick recovery without negotiating with attackers.
Control User Accounts
Ensure employees have access only to the systems and data necessary for their roles. Restricting privileges minimises potential damage if credentials are compromised.
Deploy Security Monitoring Tools
A Security Information and Event Management (SIEM) system collects and analyses data across your network to detect potential threats early.
Segment Your Network
Divide your network into smaller sections to limit the spread of ransomware. This approach prevents attackers from accessing the entire network if one part is compromised.
Enhance DNS Security
Protect against ransomware by blocking access to malicious domains and monitoring DNS activity for suspicious behaviour, such as attempts to communicate with control servers.
Email Filtering and Scanning
Since email is a common entry point, use advanced scanning tools to detect and block suspicious emails before they reach employees. Machine-learning tools can improve detection over time.
You Can Protect Your Business Against Ransomware With Cyber Awareness Training
For businesses asking what is ransomware and how you can protect your business, the key lies in fostering a workforce that understands how to identify and respond to potential threats.
However, many organisations struggle to implement comprehensive cybersecurity training programmes, leaving employees unaware of common tactics used by cybercriminals. Investing in practical, user-friendly training can make a world of difference in preventing ransomware attacks.
Conclusion!
Ransomware poses a significant threat to businesses of all sizes, but understanding its risks and taking proactive steps can help protect your organisation. From employee education and regular system updates to advanced tools like SIEM and email filtering, there are effective ways to reduce your vulnerability. By staying vigilant and implementing robust cybersecurity measures, you can minimise the chances of falling victim to these attacks.
