BackWPup release 3.6.9: Dropbox secured!

BackWPup release 3.6.9 is available: this release focus mainly on security issues to protect our users and their data.

Together with these changes, following the reports of our users, the development team has corrected some bugs and introduced improvements in order to always offer a flawless back up service.

Do not expose destination data within the manifest file and Update Dropbox Tokens

Before this release, in order to perform a restore, some sensitive data were collected and their management was left to the user.
This was the case also of a Dropbox token that, if not erased, could be used by an eavesdropper to perform unauthorized access to your Dropbox account.

In BackWPup 3.6.9 we changed the process, and sensitive data are not collected anymore: so it is crucial that you update your BackWPup version, not only for security reason, but also because the Dropbox access will not be available anymore with the older versions.

Further details are available here.

Log files name are predictable because of weak hash

A user warned us that the backup process sets the backup naming through a pseudo random algorithm: the effect was that the backup filename was predictable and could help an eavesdropper in intercepting it.

BackWPup 3.6.9 fixes the problem: the process now generates a properly randomized filename, and so it is not anymore predictable. You can sleep peacefully.

Google Drive destination: automatically remove old backup files

A similar issue was spotted in past and fixed, but it seems affecting again the version 3.6.8: even if the user decided to limit the number of backup in his/her Google Drive account, this limitation wasn’t actually performed.

Now the version 3.6.9 corrects the issue and the older backups are automatically deleted by BackWPup, as set by the user in the plugin options.
