Ransomeware: What, Why, How?

Ransomware

Protect yourself against encryption-based Ransomware

With the risk of Malware infection constantly rising and new infections spread rapidly every hour, every day. McAfee Labs, had seen a 165% rise in Ransomware in 2015 alone with newer versions of Ransomware constantly emerging.

What is encryption-based Ransomware?Encryption

Encryption-based Ransomware, for example, Cryptowall, CryptoLocker and TorrentLocker, encrypts all files stored not only on computers but also network drives. Once the infection hits, you are left with the option to either pay the ransom or give up all the precious data previously stored on the computer or other storage device.

Ransomware can covertly be installed on a computer without knowledge or intention and the attacks vary, locking the system and displaying messages intended to coax the user into paying or systematically encrypt files requiring a decryption key.

Typically Ransomware propagates as a Trojan, disguising itself as a seemingly legitimate file. For example, infection can come through, for example,  entering a system through a download file or vulnerability in a network service, to show how easy an infection can get in.

What are businesses doing to prevent attacks?

We’ve all heard about updating your operating system, installing antivirus and a security suite, avoiding suspicious files, and disabling remote access. These methods can help, but do not guarantee safety and are not a contingency plan. The real question to ask yourself is WHAT IF YOU DO GET ATTACKED? None of the above methods will help you retrieve your data back.

What is the best solution to help me get my data back if I do get attacked?

A contingency plan is a plan designed to take into account possible future events or circumstances. (There is no better way than to have multiple copies of your data) The best way to approach possible Ransomware infection is having a good method for data backup.  A recommended approach is utilising multi-version back-up so in an event where one version get locked you can still retrieve an older version.

 What if my data gets infected?

If you get hit by the infection on a local PC, you can simply retrieve the data from a backed up location.

If the Data on your backup location also gets infected you will need to look in to more advance backup methods, such as multi-version backup. Therefore in an event where the data gets held for ransom there are previous safe versions that are easily retrievable.

 file goodHow is Synology the answer to this problem.

Snapshot Replication*snapshot for WP

Snapshot replication allows the user to replicate primary site data to an offsite location up to every 5 minutes, this ensures all your critical data recovered quickly in case of infection. Snapshot replication takes a ‘snapshot’ of files allowing multiple versions giving you flexible point in time file recovery, which only uses a fraction of storage space.

 

 

 

HBUwp

Hyper Backup.

Hyper backup is a unique feature that provides you with a full range of multi-version backup destinations from shared folders, expansion units, and external hard drives, to network shared folders, R-sync server, and public cloud services.

This feature also offers secure backup protection for local backup, giving you the power to isolate data from internet threats by configuring your PC’s access privileges to certain shared folders. Configuring access privileges to certain shared folders on Synology NAS helps to prevent outside forces such as malware or Ransomware from accessing critical backup data. Hyper back up supports cross version De-duplication, reducing the amount of storage need for a given set of files saving you precious data storage space.
