Ransomware attacks are typically classified as either external or internal. These incidents involve the management, monitoring, and protection mechanisms of the information infrastructure. To prevent ransomware attacks, here are four recommendations for business owners:
1.Install reputable and credible software, and ensure that antivirus or malware protection programs are kept up to date with the latest virus patterns and detection rules. Employees should not arbitrarily disable relevant cybersecurity protection software and mechanisms.
When a system or software update message is received, it must be promptly addressed to update and patch potential vulnerabilities. This helps to avoid infiltration by ransomware or other criminal organizations using direct attacks or social engineering techniques.
- The enterprise must effectively manage asset inventory and system updates to ensure that all company-owned operating systems and applications are maintained with the latest versions and updates.
- Use external devices or services, such as external drives or cloud storage, to back up data frequently. Disconnect or remove the external drive immediately after the backup is completed to prevent it from being infected by ransomware, which could also encrypt the backup.
- Educate and remind employees not to download, open, or click on attachments or files from unknown sources. They should avoid using company computers to browse various video sites or code-sharing platforms and gain awareness around social engineering fraud techniques. For example,they should take response actions immediately if they encounter suspicious emails or files.
Additionally, disable macro execution in Microsoft Word and PowerPoint to prevent malicious files from running via macros, which could inadvertently lead to downloading malicious programs when opening attachments.
