Cybersecurity Tips to Detect and Prevent Ransomware Attacks
Data loss prevention requires multiple layers of cybersecurity for such threats as ransomware attacks, which are prevalent. In this type of cyberattack, the malware holds your data hostage and hackers promise that data will be restored in exchange for a payment of hundreds or thousands of dollars. Restoration of data often doesn’t happen even after the “ransom” has been paid.
How Ransomware Works
Once ransomware has infected a device, it scans the files, encrypts them, and makes them inaccessible. The user is notified about the cyberattack, and detailed instructions for making a payment are provided. Oftentimes, the payment is a link to a Bitcoin address, which is untraceable.
Paying the demanded money in a ransomware attack is no guarantee that a decryption key will be provided. When data is restored, at least some of the files are usually missing and/or corrupted.
Responding to a Ransomware Attack
When your network security system or an individual discovers that a company device has been attacked, damage can often be minimized with an efficient and methodical response. The following are some steps to take:
- Unplug the infected computer from the network to prevent the spreading of the problem.
- Notify all employees, including those in remote locations, to unplug from the network.
- If the company has a help desk or IT team, they should be advised and immediately get involved.
- Do not pay the ransom. If you pay, you may not get the data back, anyway. Also, it would encourage more attacks in the future.
The best cybersecurity includes a plan for backing up data and for disaster recovery. With these strategies in place, damage from ransomware attacks is significantly minimized.
