Growing macOS threat landscape and supply chain risks
Security experts warn that XCSSET’s evolution signals a growing threat to macOS, particularly through supply chain attacks that exploit trusted developer environments.
“The latest variant of XCSSET is a clear sign that macOS threats are becoming more advanced, particularly targeting developers,” said Arjun Chauhan, Practice Director at Everest Group. “With its improved stealth tactics, stronger persistence methods, and better infection techniques, this version is harder to detect and remove.”
Chauhan also pointed out that attackers are increasingly focusing on macOS, fueled by the rise of malware-as-a-service (MaaS). “The fact that XCSSET compromises Xcode projects is especially concerning because it enables a supply chain attack—meaning the malware can spread beyond just the developer’s system to the end-users of infected apps,“ he noted.
