Actually, it's not security measures so much as implementing ECMAScript 5, which explicitly says that array literals must use the built-in constructor, not any override. See 11.1.4 [1], which reads:

> Let array be the result of creating a new object as if by the expression new Array() where Array is the standard built-in constructor with that name.

Object works similarly, and is in 11.1.5. I'm not certain what earlier standards said here, but I suspect they didn't say anything.

Of course, the reason that language was introduced into the standard was primarily to mitigate this sort of attack.
