CryptoWall is a new and highly destructive variant of ransomware. Ransomware is malicious software (malware) that infects your computer and holds your data hostage in exchange for money. Older ransomware used to block access to computers. Newer ransomware, such as CryptoWall, takes your data hostage. With CryptoWall, thieves use asymmetric encryption, where the decryption key is different from the encryption key and is not stored next to the encrypted data. This forces victims to pay the thief a ransom for the decryption key to unlock the data. Ransomware presents a unique threat. It must be detected and stopped before data is maliciously encrypted, or the data may be lost and become forever unrecoverable.
So how you do protect yourself against this threat, both at home and at work? Follow these tips for general network and computer security:
Following the above advice will go a long way to preventing the CyrptoWall attack on your network, and keep your data safe.
