Injected Eitest Script

[el cabezon <elcabezzonn () gmail com>]

I've visited several websites that  follow the same pattern as rule
sid:38275, "EXPLOIT-KIT Neutrino exploit kit redirection attempt, but
replace the ascii with hex ascii. So i just converted the rule to hex ascii
to hex and followed the same template that rule, sid:38275, used. Please
let me know if this rule is too bloated. Any critiques and recommendations
are welcome.
