The WannaCry ransomware, a type of malware that encrypts a victim’s files and extorts them for money, has already affected thousands of machines worldwide. Unfortunately, the success of this attack is just the beginning. According to security researchers, other hackers will probably develop stronger WannaCry variants in the coming months. And if you don’t want your business to become a victim of these attacks, you must take the following precautions.
Update your software
The first (and probably best) defense against WannaCry ransomware is to update your operating system. New research from Kaspersky shows that machines running Windows XP, 7 and outdated Windows 10 versions were affected by the ransomware. To check whether your systems are up to date, open your Windows search bar, look for Windows Update, click Check for Updates, and install any major updates.
Also, don’t forget to download the latest security patches for your business applications and security software.
Run security programs
Many antivirus programs now have mechanisms for detecting and blocking WannaCry malware; so when you’ve fully updated your security software, run a full system scan.
Keep in mind that antivirus isn’t a foolproof security solution. Instead, run it alongside other security applications like intrusion prevention systems and firewalls.
Use data backup and recovery tools
If WannaCry does infect your computers, only a solid data backup and recovery solution can save your business. Before ransomware strikes, periodically back up your files in both an external hard drive and a cloud-based backup service.
External hard drives will serve as your local backup solution for quick recovery times. However, we recommend keeping the external drive disconnected when it’s not being used and plugging it in only when you need to back up files at the end of the day. This is because when ransomware infects a computer, it will usually look to encrypt local backup drives as well.
Cloud-based backups, on the other hand, allow you to store files in remote data centers and access them from any internet-enabled device. When selecting a cloud services provider, make sure they provide the appropriate cloud protections to your files. For example, your backup vendor should provide reporting tools to keep track of any anomalies in your files. Document versioning features are also important. This allows you to recover older versions of a document in case the current version is encrypted.
After your local and cloud backups are set up, perform regular tests to ensure your disaster recovery plan works.
Finally, it’s important to stay on guard at all times. WannaCry is just one of many ransomware strains affecting businesses today, and in order to stay safe you need to be constantly up to date on the latest cybersecurity– and business continuity-related news.
