A worrying excerpt from the enclosed article
Any cut-and-paste data temporarily stored to an iPhone or iPad’s memory can be accessed by all apps installed on the specific device – even malicious ones. That data can then reveal private information such as a user’s GPS coordinates, passwords, banking data or a spreadsheet copied into an email.
This is a significant security concern as it would indicate that any potentially sensitive data you copied - including passwords - is available via the clipboard to other application on the device. What would happen if there is another application on the device that is “less than savoury” and is listening for this type of data ?
