Security
zugbruecke is notoriously insecure by design.
DO NOT run it on any system directly exposed to the internet! Have a firewall on at all times!
DO NOT run untrusted code (or DLLs)!
DO NOT use zugbruecke for any security related tasks such as encryption, decryption, authentication and handling of keys or passwords!
DO NOT drive any physical hardware with it unless you keep it under constant supervision!
DO NOT run it with root / super users privileges!
The following problems also directly apply to zugbruecke:
Wine can in fact theoretically run (some) Windows malware.
NEVER run Wine as root! See FAQ at WineHQ for details.
zugbruecke does not actively prohibit its use with root privileges.
