How to Prevent and Recover from Ransomware Attacks
Ransomware is a type of malicious software that encrypts the victim’s data and demands a ransom for its decryption. Ransomware attacks can cause significant damage to businesses, as they can disrupt operations, compromise sensitive information, and damage reputation. According to a report by Cybersecurity Ventures, ransomware is expected to cost the global economy $20 billion in 2021, up from $11.5 billion in 2019.
How can businesses protect themselves from ransomware attacks? Here are some best practices to follow:
- Backup your data regularly:
Having a reliable backup system can help you restore your data in case of a ransomware attack. You should store your backups offline or on a separate network, and test them periodically to ensure they are working properly. - Update your software and systems: Ransomware often exploits vulnerabilities in outdated software and systems. You should keep your operating system, applications, and antivirus software up to date with the latest security patches and updates.
- Educate your employees: Human error is one of the main causes of ransomware infections. You should train your employees on how to recognize and avoid phishing emails, malicious attachments, and suspicious links. You should also enforce strong password policies and limit access privileges to only those who need them.
- Implement security measures: You should use encryption, firewalls, VPNs, and other security tools to protect your network and data from unauthorized access. You should also monitor your network for any suspicious activity and have an incident response plan in place.

How can businesses recover from ransomware attacks? Here are some steps to take:
- Do not pay the ransom: Paying the ransom does not guarantee that you will get your data back, and it may encourage the attackers to target you again. Moreover, paying the ransom may be illegal in some jurisdictions, as it may support criminal or terrorist activities.
- Disconnect the infected devices: As soon as you detect a ransomware attack, you should disconnect the infected devices from the network and the internet to prevent the spread of the infection. You should also isolate any backups that may be affected.
- Contact law enforcement: You should report the ransomware attack to the relevant authorities, such as the FBI or your local police. They may be able to provide assistance or guidance on how to deal with the situation.
- Contact a cybersecurity consultancy: You should seek professional help from a cybersecurity consultancy like TCG to recover from a ransomware attack. TCG can help you analyze the attack, identify the type of ransomware, and determine the best course of action. TCG can also help you restore your data, if possible, or advise you on how to mitigate the impact of data loss.
- Review and improve your security: After recovering from a ransomware attack, you should review your security policies and procedures and identify any gaps or weaknesses. You should also implement any recommendations from the cybersecurity consultancy to prevent future attacks.
