Microsoft is introducing a new OneDrive feature this week that will facilitate the recovery of ransomware attacks. File restore is making its way from OneDrive for companies to personal OneDrive accounts. The problem is that you will need an Office 365 subscription to access the new File Restore feature. OneDrive users can now use it to restore files from any point in the last 30 days. If you accidentally delete a file, you can restore it, or make some incorrect changes and want to revert to a previous copy.
Microsoft is promoting the File Restore feature as a good way to protect itself from ransomware attacks that block files on a local PC and often tries to delete the copies that are stored in synchronized folders by replicating those changes in the cloud. Recently we have seen several of these attacks and the victims have been forced to pay money to try to recover their files.
If OneDrive detects a massive file deletion in the cloud, Microsoft will alert users through an email or mobile / desktop notification and a recovery process will allow it to quickly restore to a time prior to the ransomware attack. "It's the first of its kind in the industry," says Seth Patton, general manager of Office 365. "We think OneDrive is the safest place to store your files."
Restoring OneDrive files
Along with this new File Restore feature, Microsoft is also adding password-protected sharing links for OneDrive to make it a little more secure when sharing confidential files or folders. Outlook.com is also being updated with email encryption for Office 365 subscribers. Email encryption can be enabled in individual messages, and Outlook.com will even ask you to encrypt emails if it detects information such as numbers of social security in the messages. Recipients can read the messages in Outlook.com, Outlook for iOS and Android, the Windows mail application, or simply by visiting a link in the email if the recipient's security level does not meet Microsoft's encrypted connection standards. Outlook.com users can also prevent recipients from forwarding or copying emails sent from the service.
OneDrive file restoration, ransomware protection and Outlook.com encryption will begin to extend to Office 365 subscribers today and for the rest of the month. Microsoft says that password-protected OneDrive links will be available in the coming weeks.
