Ransomware is one of the biggest security issues on the Internet. It is the most famous form of cyber threat businesses face today. When a PC is infected by ransomware, all of its files get encrypted and the virus spread onto the whole network. That’s why ransomware recovery needs to be a primary concern for businesses.
Ransomware affects all industries especially, business, health care departments and higher education centers. The first step in improving security is to understand how ransomware works and how to protect organizations from attacks. Read on to learn how to secure your company from ransomware.
Types of Ransomware
There are different types of ransomware, but they can be divided into two different groups. The first one locks several important functions that make your computer difficult to operate. The other type of ransomware encrypts all your files, but you are still able to view them.
How Does Ransomware Work?
Ransomware is usually spread through spams, phishing emails, or links. It can also spread via websites or drive-by downloads to infect endpoints and penetrate the network. Infection methods are constantly evolving, and there are a lot of ways that a device can become infected. The hacker will post a message in some way asking for a ransom in return for a decryption key. The best course of action you could take at this point is to get in touch with some cyber security solutions and ask for help.
How Ransomware Recovery Helps After the Attack
Here are some steps to ensure successful recovery from backup after a ransomware attack.
Isolate The Infected Device
The first thing that you need to do is to isolate the host device from other devices. Disconnect it from the network (from wires and Wi-Fi) and any external storage devices. Encryption worms are actively looking for connections and other computers, so companies can prevent this from happening.
Several Ways of Backup
In recent years, more ransomware attacks have become a business headline. Many companies are reconsidering and looking for different types of backup to protect their organizations from these growing threats. Backups can generally be categorized into two forms. On one hand, there are online backups, which are easier to store, but they could also be hacked.
On the other hand, there are local offline backups that are stored on a physical location out of the reach of the internet. Having offline backups is the best strategy to adopt as it offers advanced security and helps you get back to normal faster if an attack occurs.
Use Write-Once Storage Technology
Another way to protect backups is to use storage that cannot be overwritten. Use physical write once read many technologies (WORM) that allow writing but does not allow data modification. This will increase backup costs because it will take up more storage space. Some backup techniques only store changed and updated files, or use other deduplication techniques. It helps to prevent multiple copies of the same thing in the archive.
Don’t Pay Demanded Money
When organizations are attacked by a ransom, a common conundrum is whether they should pay the ransom or not. As a rule of thumb, you should never agree to paying a ransom as there is no guarantee that your data will be returned. You shouldn’t even consider ransom an option if you have your data saved as you could always restore it.
If you don’t have your data saved, you must weigh the cost of data loss and the required payment. Remember, you are dealing with criminals. Thus, if you pay the ransom and fulfill the demands of hackers, it will encourage them to target more organizations.
Clean Up Your System
There are some software packages that claim to remove ransomware from your system. However, it is not that simple. You cannot be sure that anyone except the attacker will be able to completely remove the ransomware. Cyber security solutions have some unique software to prevent attacks and restore your data.
After the COVID-19, the situation of ransomware got worse. Companies have witnessed a rise of more than 300% in ransom attacks after this outbreak which is an alarming situation. Ransomware recovery can be very expensive and time consuming to restore your data if you choose to pay the ransom. The best course of action is to take the services of advanced security technology to avoid ransomware attacks.
