This week Apple released security patches to address the CVE-2020-9859 zero-day vulnerability in the iOS kernel that had been used to jailbreak iPhones devices. The flaw was discovered by a team of cyber-security researchers and hackers that also released a new jailbreak package dubbed Unc0ver (from the name of the team that devised it) that works on all recent iOS versions. Apple does not allow users to have full control over their iPhones and other iOS devices, citing security reasons.”]
