TOP VULNERABILITY THIS WEEK: New Method “SandJacking” Potentially Allows

Attackers to Install Malicious iOS Apps


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: New Method “SandJacking” Potentially Allows Attackers to Install
Malicious iOS Apps
Description: Chilik Tamir of mobile security firm Mi3 disclosed a
previously unknown way of installing malicious iOS apps at Hack in the
Box - Amsterdam. Tamir previously released a proof-of-concept tool call
“Su-A-Cyder” that could be used to replace legitimate apps with
malicious ones on an iOS device. Since then, he has identified a new
technique called “SandJacking” that leverages the “Su-A-Cyder” method
which works on the latest iOS devices. The newest method leverages the
restore process. This issue has been reported to Apple, but a patch for
this has not yet been released.
