Forget Computer Hacking, your BRAIN may be the next !

I'm really shocked with this article published in the Times Group.
IT sectors are busy fighting with the word "HACK" nowadays, If computer hacking not be cured yet, What about saving brain ?

According to the experts, Hackers who can easily break into computers are giving researchers sleepless night as they hear that someday, Human mind get hacked as well.
In the last few years researchers have developed technologies that makes it possible to use thoughts to operate computers, maneuver a wheelchair or even use Twitter, all without lifting a finger. But as neural devices become more complicated and go wireless, some scientists say the risk of "BRAIN HACKING" should be taken seriously.

So what to say on this, Is it possible ?
Three questions arising here,

1. Why anyone would want to hack other's brain ?
2. What will be the wireless range ?
3. What will be the anti-hacking software then, and where to install it ?
