Ransomware is a type of malicious software that takes control of a victim’s computer and then encrypts their files, making them unreadable. These encrypted files cannot be decrypted without a mathematical key that the attacker has access to. The victim is then presented with a message telling them that their files have been encrypted and will only be decrypted if they pay a ransom in Bitcoins or another digital currency.

Typically, attackers will offer a specific amount of time for victims to pay or their decryption key will be deleted. If the ransom isn’t paid by that time, attackers will blackmail victims and threaten to release data and expose their organization publicly.

The impact of ransomware is significant, affecting productivity and data loss. Depending on the amount of damage, the recovery process can take days or weeks.

Restoring a system from a backup is the most efficient way to get back up and running. However, if the ransomware has locked and encrypted files, your backups will be useless.

After a ransomware infection, it’s important to immediately assess your backups and determine if the malware has corrupted any of them. If this is the case, you should remove all infected systems and devices from your network and delete any stored backups that may be infected as well.

Once you have a clean and healthy computer, you can begin the process of restoring the encrypted files. This process will vary depending on the severity of the ransomware infection and whether you have a recent backup that is free of the infection.
