SSH is a software which allows you to connect to your device and make changes to the file system. SSH is required by some software.
This worm is created by an Australian hacker and it will search for iPhones or iPod touches in reach of the affected iPhone or touch (It will search on available networks such as mobile, wireless, etc). If it finds a device which has the default password of SSH, set to alpine it will get installed into the device, change the home screen background image and will do the same again using that device.
- Good thing is it will not cause any harm to your device but will just change the background of the home page.
- Bad thing is the source code of the worm is out and many other varieties of worms might appear soon. Some might be dangerous.
