Android 13 is here but cybercriminal groups continue to give stiff competition to developers behind the new update. Security analysts have discovered a dropper app explicitly designed to crush new features in the latest version of Android. Speaking of malware, researchers warned against a highly pervasive .NET-based crypter, dubbed DarkTortilla. It is capable of delivering different payloads ranging from AgentTesla, NanoCore, and AsyncRat to RedLine Stealer. It has been active since 2015.
Meanwhile, Apple has issued a warning to patch two security holes that are already being used to attack iPhones. Both can allow arbitrary code execution, but one of them is through kernel privileges and the other is via maliciously crafted web content in WebKit.
