Skype On iPhone Has A Big Hole Allowing Hackers To Steal Your Information

Here’s an important advice for you and your friends: Remove Skype from your iPhone now! There’s a big hole / vulnerability which allows hackers to steal your information of all your address book content.

The hole works like that: Hackers are allowed to enter javascript commands into Skype usernames then a chat message is sent to the user and a program is loaded onto a web server to receive the address book content.

Security research from SuperEVR:

I found that Skype also improperly defines the URI scheme used by the built-in webkit browser for Skype. Usually you will see the scheme set to something like, “about:blank” or “skype-randomtoken”, but in this case it is actually set to “file://”. This gives an attacker access to the users file system, and an attacker can access any file that the application itself would be able to access. File system access is partially mitigated by the iOS Application sandbox that Apple has implemented, preventing an attacker from accessing certain sensitive files. However, every iOS application has access to the users AddressBook, and Skype is no exception.

TechCrunch says that Skype is aware of the problem:

Skype says it is aware of the security issue, and had issued the following statement:

“We are working hard to fix this reported issue in our next planned release which we hope to roll out imminently. In the meantime we always recommend people exercise caution in only accepting friend requests from people they know and practice common sense internet security as always.”
The non-patronizing first sentence would have been sufficient, Skype.

So.. take care!
