Gone are the days of harmless iPhone worms rick-rolling you into fits of laughter. The newest breach uses the same trick as the Australian version, but instead of Rick Astley you get your bank information stolen. For now the virus is contained the Netherlands, where it targets Dutch customers of ING who log into the banking system using a jailbroken phone. You also have to have installed SSH without changing your default password.
Sophos mentions dramatically reduced battery life on WiFi connections because the worm generates so much network activity. If you notice anything out of the ordinary, you should probably restore to a known safe backup. You do have one of those, right?
Luckily preventative measures are simple. Just install Mobile Terminal using Cydia and change your password from the default “alpine” to something a bit more secure. Also let this serve as a reminder that your phone is a computer capable of granting outsiders access to very sensitive data. Don’t get careless.
