When Pegasus was discovered in 2016, our perception of iOS malware changed radically. While iOS malware was previously seen more as a problem of jailbroken iPhones, it was also clear afterwards that there is also malware for iPhones on the latest version of iOS. In 2019 (Google), 2021 (Amnesty International - Pegasus II / Blastdoor), 2022 (Google - Hermit) further examples were discovered where (0-day) vulnerabilities have been exploited to infect iPhones. \n\n In this talk, I‘ll provide a detailed overview of 0-1 Click iOS Malware. The talk begins with an analysis of the previous known examples (infection, malware capabilities). After that, I present the differences between iOS malware and jailbreaks, and show possibilities and requirements for detection and development of such iOS malware. Finally, I'll present ideas to improve the detection of iOS malware.
