With the release of iOS 15 Apple has once again raised the bars in terms of kernel level security. This course will introduce you to these new security enhancements and discuss them in the light of kernel exploitation of iOS 14 and iOS 15.
For 4 full days the course will teach you how to find and exploit kernel vulnerabilities for iOS 14 and iOS 15. The course is meant for trainees with prior knowledge in exploitation that want to learn how to apply their skillset against iOS.
The course will require trainees to have an own iOS device that is compatible to the checkra1n iOS 14 jailbreak (or any other iOS 14 jailbreak that might come out until the start of the course).
Stefan Esser is best known in the security community as the PHP security guy. Since he became a PHP core developer in 2002 he devoted a lot of time to PHP and PHP application vulnerability research. However in his early days he released lots of advisories about vulnerabilities in software like CVS, Samba, OpenBSD or Internet Explorer. In 2003 he was the first to boot Linux directly from the hard disk of an unmodified XBOX through a buffer overflow in the XBOX font loader. In 2004 he founded the Hardened-PHP Project to develop a more secure version of PHP, known as Hardened-PHP, which evolved into the Suhosin PHP Security System in 2006. Since 2007 he works as head of research and development for the German web application company SektionEins GmbH that he co-founded. In 2010 he did his own ASLR implementation for Apple’s iOS and shifted his focus to the security of the iOS kernel and iPhones in general. Since then he has spoken about the topic of iOS security at various information security conferences around the globe. In 2012 he co-authored the book the iOS Hackers Handbook.
