To fully comprehend how ransomware can affect cloud storage, it can be best to define what ransomware is. Ransomware has been around for a long time but has only recently been hitting headlines due to its surge in popularity and success among cybercriminals.
This can be attributed to the fact that ransomware can damage files on the system it infects while at the same time encrypting them, thus making them unusable or inaccessible until a ransom is paid to unlock them. The ransom usually takes the form of demanded payment in Bitcoin before a decryption key can be given to victims by cybercriminals.
The answer to this question is yes. It can take only a few seconds for ransomware to infect your local data storage. Then it can begin encrypting files on both local drives and the unmapped network shares automatically. Once ransomware has encrypted your files, can ransomware affect cloud storage? This answer also hinges on whether you have mapped an unmapped network share, which will sync with the cloud. The same holds true if you use versioning software like Dropbox or Google Drive for Business that syncs changes without mapping network shares.
Let’s take a look at an example that can demonstrate how ransomware can affect cloud storage.
When you log into Dropbox or Google Drive, they can provide additional access to network shares. This can lead to the cloud sync working with ransomware-infected unmapped network shares, where files can be encrypted simultaneously on all ends, like your computer and the cloud storage. The only way to truly protect yourself against this is by keeping your data in one location.
One of the best ways to avoid having your files encrypted by ransomware is to back up often with reliable solutions like an online backup. That way, if your files are ever infected, you can restore them from a clean version stored safely offsite in the cloud.
There are different approaches to the recovery process when it comes to cloud storage. There can be three layers of safeguards:
