It uses a few other tricks to make the fake apps appear genuine, in the hopes that the user will launch them so they can perform malicious actions. It then uses macOS’s osacompile command to build fake versions of well-known apps like Safari. XCSSET first sends basic system information back to the C&C server, and kills a number of web browser-related processes. The malware downloads its main malicious payload from the server, and then the real attack begins. Once an infected app is run, XCSSET’s malicious code contacts a command-and-control (C&C) server operated by the bad guys. There’s one big unknown surrounding XCSSET: At the moment, no one is quite sure how it infects Xcode projects in the first place! But that rather significant mystery aside, we do know a good deal about how it works. In addition, because developers often share their Xcode projects with one another through public code repositories such as GitHub, an unsuspecting developer may inadvertently incorporate an infected Xcode project into their own app, thereby helping XCSSET to spread even more widely. If an Xcode project has been infected with XCSSET, and is used to assemble an app for distribution, the malicious code - unbeknownst to the developer and their end users - will be included in the official version of the app! When the app is run, the malicious code will execute. An Xcode “project” simply refers to the repository of files, information, and resources that are used to build an app for deployment.

Xcode is a tool used by app developers to write software for Apple platforms. XCSSET is a suite of malicious components that spreads through infected Xcode projects.

It’s called XCSSET, and in this article, we’ll tell you what you need to know about this unusual threat in order to stay safe. Security researchers have discovered an interesting new variety of macOS malware that spreads by attacking Xcode projects. XCSSET: New Mac malware infects Xcode projects
