A campaign aimed at Mac users is spreading the XCSSET suite of malware, which has the capability to hijack the Safari web browser and inject various JavaScript payloads that can steal passwords, financial data and personal information, deploy ransomware and more. Infections are propagating via Xcode developer projects, researchers noted; the cybercriminals behind the campaign are injecting the malware into them, according to Trend Micro. Xcode consists of a suite of free, open software development tools developed by Apple for creating software for macOS, iOS, iPadOS, watchOS and tvOS. Thus, any apps built on top of the projects automatically include the malicious code. The initial discovery of the threat came when “we learned that a developer’s Xcode project at large contained the source malware — which leads to a rabbit hole of malicious payloads,” according to an analysis [PDF] from Trend Micro, released on Friday. “The threat escalates when affected developers share their projects via platforms such as GitHub, leading to a supply-chain-like attack for users who rely on these repositories as dependencies in their own projects. We have also identified this threat in other sources including VirusTotal and Github, which indicates this threat is at large.” The initial payload tucked into the projects comes in the form of a Mach-O executable. The researchers were able to trace an infected project’s Xcode work data files and found a hidden folder containing Mach-O, located in…
