Version 1.6.6 of Viscosity has been released for both Mac and Windows! There are a number of new feature additions, improvements, and bug fixes, including an update to OpenVPN 2.3.12.
In particular this release makes it easier to manage multiple connections that share login credentials or scripting actions. Connection folders can now be edited to allow saved credentials to be shared among all connections in the folder, as well as Before Connect, Connected, and Disconnected scripts to be run for all connections in the folder as well. For more information please see Sharing Credentials and Scripts with Multiple Connections.
As part of the update to OpenVPN 2.3.12, a warning message will be now displayed in the connection log if the encryption algorithm (the cipher) being used has a block size of less than 128 bit. This is in response to the recent "Sweet32" attack against ciphers using a 64 block size.
While difficult to exploit, users receiving this warning should consider contacting their VPN Provider and encourage them to update their OpenVPN configuration to use a more secure cipher, such as AES-128-CBC. For example, this can be easily done by adding the command "cipher AES-128-CBC" to the OpenVPN server and client configurations. For more information, and other available countermeasures, please see the Sweet32 information page.
