Re: This is a very poor article.
Why did El Reg post this? Because all the AV companies create these stories if you watch. An obscure virus will have been found by one of the anti-virus companies and they put out a "Security Warning" which should really just say "Press Release" or "Advert for our product".
Almost every time the "answer" to the panic will be to buy protection from the company producing the
advert press release.
This is a classic example as it seems to imply that the hacker needs root access to install his code. Which kind of defeats the point as once you have root you can do what you like, and you certainly would not be copying in the same old code you have used elsewhere. If your hacker can get root, then you can't blame a "virus" for taking down the machine. You blame the sys admin for leaving the door open.
