There is no longer a question of whether an organization will fall victim to ransomware but rather when. Cyber criminals do not discriminate and any firm, big or small, can fall prey. They innovate their moves, and ransomware is one of the most prevalent and destructive types of viruses at the moment. From fake emails asking for personal details to unpatched systems, ransomware can take down an organization in a matter of minutes and put them under huge pressure to respond. The concept of preventing ransomware is not only about technology but, it’s more of people, processes, and products typically best security solutions. In this blog post, we will discuss the best practices to avoid ransomware and what one needs to do if they become a victim of it.
What is Ransomware?
Ransomware is a type of malware used to restrict the access of the computer system owner to the device or encrypt data until a ransom is paid in cryptocurrency. It can be in the form of e-mails sending viruses or fake links, counterfeit websites or even through unsecured or cracked software programs that have not updated for a long time. Once it infects a system, the victim is faced with two options: give up the money or have their files deleted forever. The unfortunate reality is that even when the ransom is paid, the cybercriminals who held your organisation’s data hostage may not release the data back to your organization anyway and in most cases, they do not.
The increased use of ransomware is driven by the fact that hackers realized that organizations depend on their data and networks to operate. Companies can suffer severe consequences to their profitability, image, and legal responsibilities after one ransomware attack that affects the customers’ databases.
Security Vulnerabilities – Are You a Potential Target?
Interestingly, discounting the integrity of ransomware, the hackers do not solely target large organizations. Indeed, with Internet access and quality information, anyone can be targeted. One of the biggest preconceptions that people hold is the belief that ‘my data isn’t valuable’; this is a mistake that small businesses and individuals tend to make most often. On the other hand, attackers go for the largest possible sample space, and they choose the weakest connections possible.
Here are some of the key vulnerabilities that may make you a target:
- Outdated Software: Many ransomware attacks exploit known vulnerabilities in outdated software. If patches aren’t regularly applied, attackers can exploit these gaps.
- Weak or Reused Passwords: The use of weak passwords, especially those reused across multiple platforms, can create an entry point for attackers.
- Phishing Attacks: A vast majority of ransomware cases start with phishing emails—emails that appear legitimate but contain malicious links or attachments.
- Poorly Configured Security: Organizations that don’t have proper cybersecurity measures in place, such as firewalls and endpoint detection, are more vulnerable to attacks.
- Lack of Employee Training: Human error continues to be one of the leading causes of successful ransomware attacks. Employees clicking on suspicious links or downloading unverified attachments can lead to the spread of ransomware within seconds.
Best Practices to Prevent Ransomware Attacks
Preventing ransomware attacks requires a proactive approach. The following best practices can significantly reduce the risk of becoming a victim:
1. Regular Backups
The most critical action to mitigate the damage from a ransomware attack is to maintain regular, offline backups of all essential data. Having backups stored in a separate location that’s not connected to your network ensures that you can restore your systems without paying the ransom. Remember: backups should also be tested regularly to confirm they work.
2. Patch and Update Regularly
Cybercriminals are constantly scanning networks for outdated systems with known vulnerabilities. Keeping software, operating systems, and firmware up-to-date with the latest security patches is essential in closing these gaps. A comprehensive patch management process can help ensure your software is secure from the latest threats.
3. Use Multi-Factor Authentication (MFA)
Passwords alone are no longer enough to protect sensitive data. Implementing MFA adds an additional layer of security, as it requires users to verify their identity with something they know (password) and something they have (a smartphone or token). This makes it much harder for attackers to gain unauthorized access.
4. Email Security and Phishing Awareness
Phishing attacks remain one of the easiest ways for ransomware to infiltrate a system. Organizations should deploy advanced email security solutions to detect and block phishing emails. In addition, employees should be regularly trained on how to spot phishing attempts and encouraged to report suspicious emails.
5. Endpoint Detection and Response (EDR) Solutions
Modern EDR solutions can detect and isolate ransomware infections in real time. By monitoring endpoints (laptops, desktops, mobile devices), these systems can spot unusual activity, such as encryption processes typical of ransomware, and halt the attack before it spreads across the network.
6. Network Segmentation
To minimize the spread of ransomware across your systems, network segmentation can be an effective strategy. Segmenting the network into smaller zones ensures that if one section is infected, the damage is contained.
7. Restrict User Permissions
Users should only have access to the data and systems that they absolutely need to do their job. Reducing user permissions limits the potential damage if one account is compromised by ransomware.
8. Advanced Threat Detection
Employing threat intelligence and new techniques of detection to track other people’s odd behavior. Real-time threat detection has also gained popularity as it can identify a threat and halt ransomware from executing a process of encrypting files.
9. Secure Remote Desktop Protocol (RDP)
RDP is often targeted by attackers looking to gain unauthorized access to systems. If you must use RDP, ensure it’s protected with strong passwords, MFA, and, if possible, restrict it to only necessary users.
10. Incident Response Plan
Despite best practice security, it remains an unfortunate truism that attacks can occur. First of all, the availability of a detailed incident response plan that defines what actions are to be taken if an attack has occurred is essential. It should also detail how one should, for example, isolate the affected systems, communicate with other stakeholders, and recover data from the backups.
How to Respond to Ransomware Attacks
If you find yourself in the unfortunate situation of facing a ransomware attack, time is of the essence. Here’s how to respond:
- Isolate the Infection: Disconnect the infected device from the network to prevent the ransomware from spreading to other systems.
- Inform Your IT Team: Alert your IT team immediately. They can assess the situation and take appropriate steps to contain the attack.
- Restore Data from Backups: If you’ve been following best practices, you’ll have an up-to-date backup that can restore your systems without the need to pay the ransom.
- Report the Attack: Depending on your jurisdiction, you may be required to report the ransomware attack to authorities, especially if customer or financial data has been compromised.
- Don’t Pay the Ransom: Paying the ransom doesn’t guarantee that you’ll get your data back. In fact, it often emboldens the attackers to target you again. Instead, focus on restoring from backups and bolstering your security practices.

FAQs
Q: What should I do if I receive a phishing email?
A: Don’t click any links or download attachments. Report it to your IT team immediately, and delete the email from your inbox.
Q: Can antivirus software protect me from ransomware?
A: While antivirus software can help, it is not a foolproof solution. Ransomware is constantly evolving, and some variants may slip through traditional antivirus defenses. This is why a multi-layered approach is recommended.
Q: Is it ever safe to pay the ransom?
A: Paying the ransom is strongly discouraged. There is no guarantee you will regain access to your files, and it encourages attackers to continue their operations.
Q: How can I tell if my system has been infected with ransomware?
A: Signs include unusual file extensions, locked files with ransom notes, or system slowdown as the encryption process begins. Automated tools like Lepide can help detect these anomalies early.
