Stuxnet’s malicious drivers were able to present genuine signatures from two genuine computer companies, Realtek Semiconductor and JMichron Technologies. Both firms have offices in the same facility, Hsinchu Science Park, in Taiwan. No one knows how the Stuxnet creators got hold of these keys, but it seems possible that they were physically—as opposed to digitally—stolen.
This is a highly targeted worm. It has intent to harm some very specific systems. Likely targets might include power plants or other large facilities.
Somebody knew what they wanted to hurt. Spent significant time, significant resources and significant investment on producing this worm. This wasn’t some bloke in his basement making a pointless virus because he hated the “MAN” or just wanted to get his jollies. This one has a purpose.
And experts still aren’t clear on what exactly it is going to do when it “goes off”!
One of the theories is that it was developed by Israel to slow down or damage Iran’s Nuclear Power industry.
Deep inside the computer worm that some specialists suspect is aimed at slowing Iran’s race for a nuclear weapon lies what could be a fleeting reference to the Book of Esther, the Old Testament tale in which the Jews pre-empt a Persian plot to destroy them.
