Mark Wilson writes Two minutes is all it takes to completely destroy a computer. In a presentation entitled 'How many million BIOSes would you like to infect?' at security conference CanSecWest, security researchers Corey Kallenberg and Xeno Kovah revealed that even an unskilled person could use an implant called LightEater to infect a vulnerable system in mere moments. The attack could be used to render a computer unusable, but it could also be used to steal passwords and intercept encrypted data. The problem affects motherboards from companies including Gigabyte, Acer, MSI, HP and Asus. It is exacerbated by manufactures reusing code across multiple UEFI BIOSes and places home users, businesses and governments at risk.
