A supply-chain attack involving obfuscated malicious code in the xz package was discovered by a developer at Microsoft who noticed a small 600ms delay with SSH processes when doing some routine micro-benchmarking. The account that made the offending commits seemingly played the long game, slowly gaining the trust of xz's developer before injecting the attack. The attack allows for the interception and modification of data used with the library, allowing malicious actors to break sshd authentication and gain access to affected systems. The situation is developing and more vulnerabilities could be discovered.

Linux has achieved a 4.45% market share for desktop operating systems worldwide. Its market share has been slowly but steadily growing over the past year. Several factors, such as a growing sentiment that Microsoft's Windows is faltering, the impending end-of-life for Windows 10 in October 2025, the launch of the Steam Deck, and improvements to the user experience have contributed to Linux's increasing popularity. With current trends, Linux may reach a 5% market share by the end of the year.
