Computers connected to the internet are these days facing a widespread threat from ransomware. The concept of ransomware has been around us for quite some time. However, due to the enormity of the problems caused in the PCs, they have come to limelight during the recent days. A ransomware is a kind of malware that prevents access to the programs and data stored in a system and demands to pay a ransom for removing the restriction. Here is what the users must know about them and how
On the whole, ransomware can be grouped under two heads namely those that block the system and demand the ransom for unlocking the machine, those that encrypt a huge amount of data on the computer and demanding the ransom to unlock those files. The main objective of the cyber criminals behind spreading ransomware is to extort money from the victims by targeting a wide range of devices and diverse kinds of operating systems. Once a system is infected with ransomware, the victim finds a message displayed on the screen informing of what has happened to the system and directing the victim to make a payment through cryptocurrency like bitcoin. If you would like to clean your system from ransomware attack, here is a step by step process to recover your system from ransomware.
Initial steps to recover from ransomware
Using the decryption tool
You can visit malware hunter team which is a free web service to get assistance with decryption. Host an infected file or ransom note and the program will detect the ransomware family and prescribe you the right decryption tool appropriate to deal with it. Once the recommended tool is downloaded, set the key used by the ransomware to encrypt the files. Once the extension found appended to the encrypted files is selected, the recovery tool will automatically set the master key. Now you can start recovering the files. In some cases, the tool can decrypt 100 % of the files on the computer.
Recovering shadow copies
Usually, Windows OS makes a volume backup of your data from time to time which is called as shadow copies. These are restored when you use the system restore option when needed. Once you have used the decryption tool, you must also inspect your shadow copies. There might be two or more restore points available. You must choose which data to recover and right click on the folder to explore the files inside. If the shadow copies are not infected by the ransomware, you are lucky. In case you find them also encrypted by ransomware, you follow the process above to restore the encrypted files on the OS hard drive.
Data recovery refers to the repair of the data that is lost. If the damage inflicted by the ransomware is serious, then much of the data recovery might not be possible. Choose a reliable data recovery tool available online for free. Install the tool on an external USB drive without installing on the OS drive. This will increase the possibility of recovering more data. After installation, the tool will prompt a scan. Close this wizard and set the following options. Activate ‘Restore Folder Structure’ to preserve the directory tree structure and get to know all the encrypted files easily. Following this, run the scan on the drives you desire. Note that some files are recoverable, some are not and some can be partly recovered. Select those files you wish to recover and export them to the desired location. Export the data to an external drive to recover as much data as possible.
Ransomware can be a big nuisance once it has infected your system. If the data you have stored in the system are valuable, then your peace is at stake. The best thing to prevent a ransomware attack is to follow some safety practices while staying online. Never download or open the files that you receive from unknown sources. Usually, the links to ransomware are forwarded through emails. In many cases, they are also hidden under the malvertisements you can find online. Learn and implement all those safe browsing habits to stay away from ransomware since the implications and the cost you pay for recovery from a ransomware attack can be unmanageable at times.
