Antid0te: Jailbreak Protects Malware

A German security analyst is about to unveil
a new jailbreaking process that will make
iPhones much more secure. Stefan Esser, a
security consultant and application developer
for SektionEins, has found a way to support
Address Space Layout Randomization (ASLR) in iOS, and has developed a new
jailbreak tool – to be called antid0te – to implement it, making iPhones much more
resistant to malware attacks. The tool will be
announced at a security conference next
week and should be available soon
thereafter. Esser will be presenting antid0te at the
Power of Community security conference in
Korea on December 14th. “With ASLR,” the conference notes explain, “an exploit mitigation is added that is not available in
factory iPhones and makes exploitation more
difficult.” And according to Esser, he’s going to continue to work on further hardening the
iPhone: “more mitigations and a full reactivation of the codesigning protection are
planed for the next months.
