MacRumors published a story that a new Mac malware is in the wild that targets Xcode projects.

New Mac Malware Found to Infect via Xcode

Security researchers at Micro Trend have discovered a new kind of Mac malware which can "command and control" a target system. The researchers described the malware, which is part of the XCSSET family, as "an unusual infection related to Xcode developer projects." The malware is unusual because it is injected into Xcode projects, and when the project is built, the malicious code is run. A developer's Xcode project was found to be able to contain the malware, which "leads to a rabbit hole of malicious payloads." The discovery poses a significant risk for Xcode developers.
