you might have seen Leslie Stahl’s segment about the conficker virus. The link above is the ultimate tech rundown of what Conficker is and how it propagates. How it’s eventually going to be used is anyone’s guess. Money Shot:
The exploit employs a specially crafted remote procedure call (RPC) over port 445/TCP, which can cause Windows 2000, XP, 2003 servers, and Vista to execute an arbitrary code segment without authentication. The exploit can affect systems with firewalls enabled, but which operate with print and file sharing enabled. The patch for this exploit was released by Microsoft on October 23 2008 [3], and those Windows PCs that receive automated security updates have not been vulnerable to this exploit. Nevertheless, nearly a month later, in mid-November, Conficker would utilize this exploit to scan and infect millions of unpatched PCs worldwide.
Why Conficker has been able to proliferate so widely may be an interesting testament to the stubbornness of some PC users to avoid staying current with the latest Microsoft security patches [2]. Some reports, such as the case of the Conficker outbreak within Sheffield Hospital’s operating ward, suggest that even security-conscious environments may elect to forgo automated software patching, choosing to trade off vulnerability exposure for some perceived notion of platform stability [8]. On the other hand, the uneven concentration of where the vast bulk of Conficker infections have occurred suggest other reasons. For example, regions with dense Conficker populations also appear to correspond to areas where the use of unregistered (pirated) Windows releases are widespread, and the regular application of available security patches [9] are rare.
