Malware: Fighting Malicious Code

Conclusions

Well, crafty attackers certainly have cooked up a putrid feast of different types of backdoors, all designed to bypass our normal security controls. Yet, their nastiness doesn't stop with the techniques we've discussed in this chapter. So far, we've just seen how attackers get their backdoors running, and how they communicate with them across the network. We've just scratched the surface. In the next chapter, we'll delve into the details of how attackers disguise their backdoors to make them look like benign programs. As we shall soon see, attackers use Trojan horse techniques to dress up the backdoors we've discussed in this chapter, making discovery of the backdoors an even trickier process.
