I agree completely, and have blogged to much the same effect on securiteam,
(ISC)2 and ESET's site, and added comments to other blogs. It's not often
I'm passionate enough to write that much on a single issue.

I personally felt somewhat ill when watching the program.  So, why? 

For me, the legal issue is only one part of this.  While I do 
agree with the legal analysis, there is a deeper moral and 
ethical issue here.  The BBC will get out of any legal 
trouble with an argument for the "greater good", and that "no 
harm was done".  And they'll win on that argument.
End of story. 

But malware researchers routinely deal with botnets for 
analysis purposes.  It would be considered a high crime 
indeed to allow a spambot to actually send spam to the 
outside world, even for "testing" purposes.
And, shutting down a botnet yourself, even with the best 
intentions, is simply not a good idea.  You don't know what 
accidental harm you may cause.  You also don't really know 
what's on the user's system that will simpy restart the whole 
process.  

I've personally come across dozens of these things, as many 
of you have.
I know my personal feeling is always to get the hell out of 
there.  We need to know what we need to know in terms of 
mitigation, etc. but you just don't mess with these things. 
You don't get involved, because it's not only wrong, there 
are too many unintended consequences that can occurr.  You're 
playing with fire.  Report it to the ISP, report it to the 
relevant authorities, but don't play with live ammo like this.

It's highly disturbing that the BBC has, in effect, set a precedent
here:  If it's all for the good, then no worries, go ahead, 
blunder around and disable botnets, change user's desktop 
settings, show off how they send spam -- it's all ok, because 
the means justifies the end. 

Doesn't work for me.  At all. 

Alex

Come to think of it, isn't a botnet a computer system?  
Wouldn't that make it illegal to dismantle it, or hamper 
its operation

in any way?

Maybe. It can certainly be argued that modifying data (the 
wallpaper) and the bot  on individual zombie machines is in 
breach of section 3.

3     Unauthorised modification of computer material 

(1) A person is guilty of an offence if-
(a) he does any act which causes an unauthorised modification 
of the contents of any computer; and
(b) at the time when he does the act he has the requisite 
intent and the requisite knowledge. 

(2) For the purposes of subsection (1)(b) above the requisite 
intent is an intent to cause a modification of the contents 
of any computer and by so
doing-
(a) to impair the operation of any computer;
(b) to prevent or hinder access to any program or data held 
in any computer; or
(c) to impair the operation of any such program or the 
reliability of any such data. 

(3) The intent need not be directed at-
(a) any particular computer;
(b) any particular program or data or a program or data of 
any particular kind; or
(c) any particular modification or a modification of any 
particular kind. 

(4) For the purposes of subsection (1)(b) above the requisite 
knowledge is knowledge that any modification he intends to 
cause is unauthorised. 

(5) It is immaterial for the purposes of this section whether 
an unauthorised modification or any intended effect of it of 
a kind mentioned in subsection (2) above is, or is intended 
to be, permanent or merely temporary.
