These types of attacks are usually directed at routers or firewalls in order to shut them down to gain access to other computers on the network. A router is very susceptible to these types of attacks but a firewall can usually handle the attack and is unaffected. A distributed denial of service attack is when communication requests come from multiple computers, greatly increasing the number of requests over a regular denial of service attack.
This technique is mainly used to collect passwords when a host machine uses a password to be connected to. When this type of attack takes place the victim and the attacker must be on the same network. Port Scanning Port scanning is simply a way to figure out which ports are accepting and listening to connections.
The hacker would just use a program that lets him know which ports are open by scanning all the ports on a network and trying to open them. Reach Out and Hack Someone This part is about finding vulnerabilities in the typecasting of the network. Using a debugger to go through lines of code which are used for network protocols is the most efficient way to accomplish this. It is like the hacker's own code that he wants to run when he gains control over a program.
Usually a hacker will find an exploit in a programs code and be able to insert some of his own code shellcode where he found the exploit. Assembly vs. C Assembly differs from C because assembly is a low-level programming language and when processed can communicate directly with the processor.
When using C, which is a high-level programming language, the code must be compiled and sent to the kernel by making a system call and then making a call to the processor. In other words, it is almost like taking the system calling to the kernel out of the picture when using assembly. There are many examples of code in the book and ways to accomplish this task.
Self-spawning shellcode Spawning shellcode is code that will be enabled when an exploit is found. It is shellcode that will be able to be run when a vulnerability is found in the program.
The best way to accomplish this is shown in the book and by making sure the code is very small. Port-binding shellcode This type of shellcode attaches itself to a network port. Once bound to a port it will listen for a TCP connection.
After it finds the TCP connection there is a lot more programming involved and is shown vividly in the book. Connect-back shellcode This type of shellcode is mainly used when getting around firewalls. Most firewalls are going to block port-binding shellcode from working because they are set up to only allow known services through the active ports. Connect-back shellcode initiates the connection back to the hacker's IP address so it will be coming out from the firewall instead of going into it.
Once again the code in the book depicts connect-back with the use of shellcode and ways to accomplish this.
Countermeasures That Detect An administrator of the network has to be aware of when an exploit may be occurring. Using certain tools like reading logs or packet sniffing on the network are a few ways to catch exploits when they occur. System Daemons A System Daemon is a server program on a Unix system which receives and accepts incoming connections. A daemon is a program which runs in the background and detaches from controlling the terminal in a certain way.
At this point in the book there is some code shown on how to run a daemon program. Signals are also used in a Unix-based environment to make operating system calls. When a signal is type in the terminal it will immediately send an interrupt message to complete the task of whatever the signal was which was typed.
