Since the COVID-19 pandemic, cyber-attacks are on the rise. This is because the pandemic had forced businesses to work remotely. Companies were not prepared for this sudden change, which is why cybercriminals have increased their attacks. They can easily locate vulnerabilities in the networks and systems. Plus, they target those vulnerabilities to hijack their data. Therefore, all businesses are in dire need to re-evaluate their enterprise security strategy and ransomware recovery plans.
After a ransomware attack, things aren’t as simple as restoring from backup and returning to business as usual. You have to go through a lot of things to bring your company to normal. This is why it is very vital to have data protection services to avoid ransomware in the first place. And if somehow ransomware infects your system or files, you should have a recovery plan to avoid reinfection or extended downtime (the real cost of ransomware). Before going into depth, let’s get the basic knowledge about ransomware.
Introduction of Ransomware
Ransomware is malware that when enters into a network, encrypts files and operating systems. As a result of which, the users will not be able to access key data stores and their computers become completely inoperable. Once ransomware is installed on your system, you get a warning screen that provides detailed payment instructions that, if followed, will restore access to the ransomware encrypted files.
After paying the ransom, the operators typically send the victim a set of decryption keys that will decrypt files. However, sometimes, even after paying the ransom, the attackers don’t return the control and run away. This menace can spread in a number of ways but the most common method cybercriminals use is email phishing. They send provocative emails to the employees of the company they want to target.
These emails contain either an infected link or an infected attachment. And when the user of the system clicks on the link or tries to install the attachment, the process of ransomware starts. One thing to remember here is that method of a ransomware attacks can destroy even the most advanced and enterprise security strategy of your organization.
Some Points You Can Try for Ransomware Recovery:
Keep Daily Backups of Your Data
The first and foremost step that you can take to clear the ground for recovery is to keep backups of your data. This is because, in an event of misfortune, backups will save you from paying ransom and downtime costs.
These days’ storage is not as costly as it was in the past, so, taking this measure won’t cost you much. Furthermore, to keep these backups safe from the attack, either they should be kept offline or off-site. When they are disconnected from the network, the attackers won’t reach them.
Isolate the Infected Part
Before trying anything, isolate the system that is a victim of an attack from the network. This will save you from the greater damage. If you don’t do this, the ransomware will spread to other computers in your organization (if it has not already).
To do this, simply disconnect that system from the internet and shut down the system. Furthermore, before going offline, it is better to log out of any cloud storage connected to your browser.
Keep Your Software Applications Updated
The cybercriminals are always after the possible vulnerabilities in the software and the system. They exploit those vulnerabilities to launch their attacks. And the software providers, on the other hand, always try to remove the vulnerabilities of the current version with the new version. This is why it is important that you should always be up-to-date with your systems and software applications.
Furthermore, when a cybercriminal attacks your system, your antivirus and firewall are the first shields that will save your data. Also, they will save you from greater disasters because they will inform you as soon as the ransomware attack begins. Thus, it is vital to get good quality antivirus and you should install a firewall on all of your systems. Moreover, don’t forget to keep them updated too and take data protection services.
Method of Window Restoration
You can try to restore your files with the help of window restoration when you become a victim of ransomware. You can restore your window to an earlier point of time; doing this will return most of your data. However, you will not get cent percent data.
You can use this recovered data to create the remaining files. One thing you must keep in mind, before trying any ransomware recovery technique is, remove the malware from your system, otherwise, recovery will do no good to you.
