Errata has also discovered that by exposing the Bluetooth receiver to a "fuzzer" -- a stream of random data -- it is possible to cause the whole phone to lock up. This can be undone by manually rebooting the device. Further efforts, this time by members of the Hackint0sh user forum, have revealed passwords used to gain access to key components. Applications require the word "dottie" to gain root access, while gaining mobile access can be done with "alpine." These were discovered by running the popular John the Ripper cracking program. The passwords are not immediately useful however, as people have not actually managed root access. "As of yet," comments security researcher Kevin Finisterre, "those passwords do not have a specific use, but that's not to say that within the next 20 minutes somebody finds a service on port 123 and we can log into it." Finisterre does believe though that it is just a matter of time before a root hack is discovered, and that elements such as DRM guards may be overcome as well. "I don't think enough researchers like myself have the iPhone in their hands," he says. "Once folks like us get a hold of the thing, I think you're going to see quite a bit of stuff go on."
