Experts send malicious code to 37,000 users
The code posed as a so-called exploit, a program that identifies security flaws in a computer system. In this case, the exploit related to four flaws recently discovered in the common domain-name-service software known as the Berkeley Internet Name Domain, or BIND.
In reality, the exploit code attempts to use any computer on which it runs to send a simple form of Internet data to a single domain name server, in an attempt to overwhelm the computer with information. That server, it turns out, belongs to the company that found many of the BIND flaws: Network Associates.
