Ransomware attacks are a growing threat to individuals and organisations around the world. This type of cyber threat involves hackers encrypting a victim’s data, rendering it inaccessible, and then demanding payment in exchange for the decryption key. In this blog, we explore how ransomware attacks work and provide tips for prevention and recovery.
Understanding ransomware attacks
Ransomware attacks typically start with a phishing email, a malicious website, or an infected attachment. Once the ransomware is downloaded onto the victim’s system, it begins to encrypt the victim’s data, rendering it inaccessible. The victim is then presented with a message that demands payment in exchange for the decryption key, usually in the form of cryptocurrency such as Bitcoin, which is difficult to trace.
Tips for prevention
It’s important to be vigilant and prepared if you want to prevent ransomware attacks. Follow these tips to keep your business safe:
- Train employees on cybersecurity best practices
Phishing emails are a common starting point for ransomware attacks. Educating employees on how to identify and avoid phishing emails can help prevent ransomware from infecting your system in the first place.
- Keep software up to date
Hackers often target vulnerabilities in outdated software to gain access to a victim’s system. Keeping your software up to date with the latest security patches can help prevent ransomware attacks.
- Use antivirus software
Antivirus software can detect and prevent ransomware attacks. Be sure to keep your antivirus up to date with the latest version.
- Limit access to sensitive data
Limiting access to sensitive data can help prevent ransomware from spreading throughout your organisation. Implementing a least privilege model can help ensure that employees only have access to the data they need to do their jobs.
- Backup data regularly
Regularly backing up your data can help minimise the impact of a ransomware attack. If your data is encrypted, you can simply restore from your most recent backup.
Tips for recovery
Need help to get back up and running? Explore our list of recommendations below:
- Do not pay the ransom
Paying the ransom does not guarantee that you’ll get your data back. In fact, it can encourage hackers to continue their attacks.
- Isolate infected systems
Isolating infected systems can help prevent ransomware from spreading throughout your organisation.
- Remove the ransomware
Once you’ve isolated the infected system, you can begin to remove the ransomware. This may involve using antivirus software, restoring from a backup, or even wiping the system and starting over.
- Restore from backup
If you have a recent backup, you can restore your data and systems to their pre-attack state.
- Report the attack
Reporting the attack to law enforcement can help prevent future attacks and may even help you recover your data.
Combine prevention with recovery to safeguard your brand
Ransomware attacks are a serious concern for individuals and organisations around the world. However, by following best practices you can reduce the risk of such threats. If you do fall victim to a ransomware attack, it’s important to isolate infected systems, remove the ransomware, restore from backup, and report the attack to law enforcement. By taking these steps, you can stay safe and prevent future issues.
