Too bad the author picked the MIT license. Had they picked (A)GPL, it would have forced the criminals to distribute a copy of LICENSE.TXT alongside their improved copy of the source code on systems they compromise. Failing this, using it in that way would be both a crime and an instance of copyright infringement.

Although, it occurs to me that if they don't give credits to the original author, it's also already a copyright infringement under the MIT.
