Reduction of Code Reuse Attacks Using Code Randomization and Recursive Traversal Algorithm

other code reuse attacks are a class of buffer overflow attacks that shows the existence of executable code that can be used for malicious purposes. They attack the systems security by chaining the sequence of instructions together to perform the expected logic of attack. These attacks have a common feature; they rely on executable code’s memory layout. The layout of the executable code can be modified to avoid code reuse attacks. In marlin we change the internal structure of executable code by shuffling the target binary’s function blocks in random manner. This will not allow the attacker to gain information of the instruction addresses, which will result in reduced possibility of attacks. Marlin can be implemented with any ELF binary code and every execution of the binary code will be using different randomization techniques. The target executable binary will be randomized before launching by integrating marlin to the bash shell. Thus our system reduces the vulnerability of security against attacks based on code reuse.
