Investing of network and physical based cyber threats and hiding methods with digital forensic analyses

With the advancement of today's technology, we use systems such as phones, computers, internet, smart systems, e-commerce, etc. in our lives. However, while using these systems, we also put our cyber security at risk and at this point, an open door is left for malicious cyber attackers. In this thesis, the cyber weapons used by cyber attackers and their methods of hiding themselves will be investigated and the damages caused by these attacks will be analyzed. With the advancement of technology, cyber-attacks are not only carried out using computers, but now specially developed or developable devices are produced for cyber-attacks. By talking about the programs, technologies and software used by cyber attackers to hide themselves and cover the traces when and after they carry out attacks, tests were carried out and test outputs were shared. Flipper Zero, HackRF, Digispark, which is a popular cyber attack device used globally for cyber security, was turned into a cyber attack tool after using and programming the necessary programming tools if necessary, and the outputs were shared by testing in the experimental environment. It is thought that the thesis study will contribute to cyber security experts and researchers in preventing threats and increasing the attack surface, and will raise awareness about network and physical-based cyber threats and hiding methods.
