How to remove CryptoDefense virus and restore your files

Ransomware that encrypts files within the operating system has been quite popular for the past year. And it is no surprise that NAS computers were hit recently with a version of encrypting ransomware designed just for them called CryptoDefense Virus. NAS computers are file-level computer data storage devices. They are usually connected to a computer network providing data for clients on the network. NAS computers are quite popular as they are very convenient for sharing various files among multiple systems. These computers can be simply configured compared to traditional file servers; also, NAS systems provide faster data access and easier administration.

This particular ransomware targets Internet-exposed Synology servers and utilizes a hereto-unknown exploit to break into these systems. After a successful infiltration, CryptoDefense Virus starts encrypting files in a similar manner as Cryptolocker or CryptoWall ransomware does. These computers are run exclusively on the DSM operating system that is a mixture of Linux and Windows operating systems that allow NAS computers to run smoothly and efficiently. It has been noticed that systems running the outdated version of the DSM operating system (to be precise versions prior to DSM 4.3-3827) are affected mostly. The newer versions of the DSM OS (DSM 4.5) are not vulnerable.

Once the NAS computer is infected with CryptoDefense Virus, users are presented with a message. It states that all the important files on their NAS were encrypted using strong cryptography. The message provides a link to see the exact list of files that were encrypted. Furthermore, the user is asked to pay the ransom of 0.6 Bitcoins (roughly $350 USD). Users that are infected with this invasive infection are urged to shutdown their systems as soon as possible to prevent any further files from being encrypted. It is also advised to contact Synology (the company that produces the DSM operating system for NAS computers) for further assistance.

If you have been able to avoid this dangerous virtual threat, you are advised to disable the external Internet access to your NAS computer. In addition to that, you are encouraged to update the DSM operating system immediately. It goes without saying that you must backup all of your data. Furthermore, you should be extra careful about the emails that you receive from Synology as some malware researchers believe that CryptoDefense Virus might be distributed in this manner.

CryptoDefense Virus is an extremely dangerous infection because it affects NAS systems. NAS computers are usually used to store larger amounts of data compared to an average PC. Moreover, data of such systems is usually more important compared to the average client machine. If you have an NAS machine running, you should check it for any abnormal behavior. Furthermore, it is firmly advised to implement a reliable protection tool for your NAS system.
