Other comments provide links to licenses similar to what you are looking for. But I’d like to argue that the MIT/BSD2 licenses are _better_ than a “no strings attached“ license, even when one wants to give the broadest permissions to use and modify a piece of code. The obligation to preserve attribution and license is as unobtrusive as possible, and at the same time gives assurance that the code is actually properly licensed. The typical corporate entity will not trust a piece of code with no license and would have to track copyright and license in some database. Having the same information in the source files makes things easier.
