Jungle Disk

Jungle Disk is an online backup tool that stores its data in Amazon S3 or Rackspace Cloud Files. It was highlighted by Amazon as one of the earliest S3 clients ^[1] The basic Jungle Disk software is sold as a monthly subscription model, and the customer is billed directly by Amazon for data storage and transfer.

Jungle Disk can periodically back up selected files or folders. It provides a local webdav server and a local web interface that synchronize to the user's S3/Cloud Files account, optionally encrypting backed up data on the client side. For a monthly fee, the company will provide a hosted web interface and more advanced backup functionality. ^[2]

Jungle Disk supports Linux, Mac OS X and Windows.

On October 22, 2008, Jungle Disk entered into an agreement to be acquired by Rackspace Hosting, Inc. Rackspace purchased Jungle Disk in order to expand their cloud hosting services. Although owned by Rackspace, Jungle Disk continued to provide services with no changes to existing customers until November 2009 when the product line up was changed to a subscription-only model. ^[3]

Criticism

On June 3, 2011, Colin Percival identified two serious weaknesses in Jungle Disk's security^[4]:

• The lack of a Message Authentication Code means that file corruption (accidental or deliberate) or arbitrary file content insertions^[5] will not be detected
• The use of MD5 as a Key derivation function makes it easy to perform a brute-force attack on the Jungle Disk password.
