um - you can locate the oracle data block you want to corrupt, set the input file to /dev/random and the output to the datafile name specifying the block. (man dd)

Why would you want to do this?

Of course you could open the file in an editor and write junk over the middle.

Or maybe you want an oracle version of this:
