Worms are self-replicating malicious programs that represent a major security threat for the Internet, as they can infect and damage a large number of vulnerable hosts at timescales where human responses are unlikely to be effective.
Sophisticated worms that use precomputed hitlists of vulnerable targets are especially hard to contain, since they are harder to detect, and spread at rates where even automated defenses may not be able to react in a timely fashion.
We assume that a worm has already penetrated a system and is trying to hide its presence and propagation attempts from an IDS.We focus on stealthy worms that cannot be reliably detected by increases in traffic because of their low propagation factor.We first give an example of a simple polymorphic worm.

 A Tour of the Worm
If the worm's files are somehow captured before the worm can delete them, the object files have been loaded in such a way as to remove most non-essential symbol table entries, making it harder to guess at the purposes of worm routines from their names.
Finally, new worms lose all of the history of infection that their parents had, so the children of a worm are constantly trying to re-infect the parent's host, as well as the other children's hosts.
The worm is careful to skip the loopback device and any local interfaces (in the event that the current host is a gateway); when it finishes, it randomizes the order of the list and adds the first 20 gateways to the host table to speed up the initial searches.

Now it has been 7 years since the Worm was defeated, but it is still worth looking at what happened, both in terms of how the program operated, and as to what conditions allowed it to do what it did.

 Nachi worm infected Diebold ATMs
The Nachi worm compromised Windows-based automated teller machines at two financial institutions last August, according to ATM-maker Diebold, in the first confirmed case of malicious code penetrating cash machines.
Though ATMs typically sit on private networks or VPNs, the most serious worms in the last year have demonstrated that supposedly-isolated networks often have undocumented connections to the Internet, or can fall to a piece of malicious code inadvertently carried beyond the firewall on a laptop computer.
"But worms are always going to be able to infect a lot more interesting machines than individual intruders are." Moreover, before reaching an ATM network, a human attacker would likely encounter more alluring high-finance targets along the way.
