Skype On iOS Is Vulnerable For Attack

A new vulnerability has been uncovered that could help hackers steal personal information from your iPhone and the cross-site scripting (XSS) vulnerability is present in the current version of Skype, 3.0.1. Basically it means that when Skype users view a message, a hacker could have a JavaScript code that runs a check on a locally stored HTML file that is currently not encoded properly and revealing the user’s Full Name data field………………..

Skype‘s iOS app is vulnerable to an attack that can compromise your entire address book without you noticing and TechCrunch reports that Skype for iPhone and Skype for iPad have a cross-site scripting vulnerability in the Chat message window, which allows an attacker to run malicious javascript code that can enable the attacker to get information, including a user’s address book from the victim’s iOS device. AppSec Consulting security researcher Phil Purviance who discovered the vulnerability explains:

Executing arbitrary Javascript code is one thing, but 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.


He apparently reported the security issue to Skype nearly a month ago. Skype has acknowledged the issue and has 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.”
