The attack was spotted by Microsoft and acknowledged by intelligence and infosec agencies from the Five Eyes nations - Australia, Canada, New Zealand, the UK and the US.

Microsoft has updated PowerToys with two new tools that help control multiple Windows systems with the same keyboard/mouse and quickly preview various file types. As its name implies, the new Mouse Without Borders utility can let users control up to four computers using a single mouse and keyboard.
It does exactly what the name suggests: Users can drag and drop unstructured data from Excel - or give Copilot a link to the file - and the Power Platform will analyze it, enrich it with the extra information Dataverse needs, and turn it into an app, Nirav Shah, the vice president of Dataverse at Microsoft explained to TechRepublic. Data in Excel might be easy for users to work with individually, but bringing it to Dataverse connects it to a range of new AI tools.
