Apparently more QA required for government malware producers
The malware was so skillfully designed that computer security specialists who have examined it were almost certain it had been created by a government and is a prime example of clandestine digital warfare. While there have been suspicions of other government uses of computer worms and viruses, Stuxnet is the first to go after industrial systems. But unlike those other attacks, this bit of malware did not stay invisible.
If Stuxnet is the latest example of what a government organization can do, it contains some glaring shortcomings. The program was splattered on thousands of computer systems around the world, and much of its impact has been on those systems, rather than on what appears to have been its intended target, Iranian equipment. Computer security specialists are also puzzled by why it was created to spread so widely.
