0 Distributed DOS Attacks


Please Leave A Comment~ Thank You...!!!

DOS attacks are not new; in fact they have been around for a long time. However there has been a recent wave of Distributed Denial of Services attacks which pose a great threat to Security and are on the verge of overtaking Viruses/Trojans to become the deadliest threat to Internet Security. Now you see, in almost all of the above TCP/IP vulnerabilities, which are being exploited by hackers, there is a huge chance of the target's system administrator or the authorities tracing the attacks and getting hold of the attacker.

Now what is commonly being done is, say a group of 5 Hackers join and decide to bring a Fortune 500 company's server down. Now each one of them breaks into a smaller less protected network and takes over it. So now they have 5 networks and supposing there are around 20 systems in each network, it gives these Hackers, around 100 systems in all to attack from. So they sitting on there home computer, connect to the hacked less protected Network, install a Denial of Service Tool on these hacked networks and using these hacked systems in the various networks launch Attacks on the actual Fortune 500 Company. This makes the hackers less easy to detect and helps them to do what they wanted to do without getting caught. As they have full control over the smaller less protected network they can easily remove all traces before the authorities get there.

Not even a single system connected to the Internet is safe from such DDOS attacks. All platforms Including Unix, Windows NT are vulnerable to such attacks. Even MacOS has not been spared, as some of them are being used to conduct such DDOS attacks.
