Remove CORE ransomware + Decrypt locked files

Effective measures to delete CORE ransomware

CORE ransomware can lead to severe data loss problem because it locks the targeted files and makes it inaccessible. The files and programs that were easily accessible earlier are now showing error messages when you try to access them. This dubious malware uses AES-128 and RSA-2048 cryptographic algorithms for locking the files. They do quick scan of hard disk in search of the files that it can encrypt. After finishing encryption process, the data become inaccessible and are totally blocked for you by using victim’s unique ID, cyber criminals email address and by appending .CORE extensions.

Details about CORE ransomware

Ransomware are always considered as one of the dangerous PC infection because it is not always possible to restore the files that it encrypts. As soon as encryption process completed, a ransom demanding message #CORE_README#.rtf are placed into every compromised folders that contain encrypted files. The developers behind CORE ransomware who is cyber criminals states that all files are encrypted and in order to retrieve them you have to pay ransom money to buy decryption key. In order to contact them, email address has been provided under the ransom note. Users are also suggested to use alternative email address if they did not receive the response from the cyber criminals within 24 hours.

Before paying money, they offer free test decryption of up to 3 encrypted files as the size of the file is not more than 5mb as well as does not contain any valuable information. However, it is never recommended to pay any money to them. Paying the money to the cyber criminals doesn’t guarantee that you will get the decryption tool. In most of the cases, they take the money and don’t provide any proper solution. Thus, it is always advised that you should maintain proper backup files of your important data. The backup should be created in some external storage device so that you can use it to restore the encrypted files in this kind of situations.

How to restore encrypted files?

To keep other files and programs safe, you are advised to remove CORE ransomware as soon as possible from the computer. Remember that removing the malware doesn’t restore the files but prevent it from further encryptions. After that recover your files using backup (if someone has created earlier before encryptions). In case, backup files are not found you must see whether “Shadow Volume Copies” (short backup files created by OS) are available or also been deleted. The last option is to use third party data recovery tool.

Precautionary measures to avoid malware attack:

• Update all installed programs and OS regularly from legitimate sources.
• Avoid visiting untrustworthy websites such as free file hosting sites, third party installer etc.
• Stop opening email attachment that look suspicious and are sent by some unknown senders.
• Use only official websites and direct links for any software download.
