The following link was contained in a spam email.  It probably tries to
trigger a browser exploit of some sort, so handle this with care:


The server responds with this:

<html><body><script type="text/hello">ykzjr1="\x30";

Just in case the above would have executed for some readers, I replaced
"javascript" with "hello" on the first line.  The above would have given
this news server a "line too long" error, so I broke the line after the
";" in various locations (if it matters).

What does that script decode to, or try to do?

Is there an on-line javascript decoder that would have processed the
above and given some sort of report or decoded result?

VT URL scan gives 2 / 53 in terms of detection as a malicious site
(based on IP / domain of URL and not on contents or files returned?)

VT scan on "sensors.php" returns 2 / 50:
