Research ‘net: Dirt jumper -smart
Distributed Denial of Service (DDoS) attacks are often used to hold companies—particularly wealthy companies, like financial institutions—to ransom. Given the number of botnets in the world which can be purchased by the hour, and the relative ease with which new systems can be infected (especially given the rise of the Internet of Things), it’s important to find new and innovative ways to protect against such attacks. Dirt Jumper is a common DDoS platform based on the original Dirt, widely used to initiate such attacks. Probably the most effective protection against DDoS attacks, particularly if you can’t pin down the botnet and block it on a per-IP-address basis (try that one some time) is to construct a tar pit that will consume the attacker’s resources at a rate faster than your server’s are consumed.
The paper linked here describes one such tar pit, and even goes into detail around a defect in the Dirt Jumper platform, and how the defenders exploited the defect. This is not only instructive in terms of understanding and countering DDoS attacks, it’s also instructive from another angle. If you think software is going to eat the world, remember that even hacking software has defects that Continue reading
