Técnicas anti-forenses em computadores pessoais

Abstract

The evolution of information technologies and the increase of users in the digital environment also resulted in the increase of the number of crimes in the virtual environment, as well as the complexity of them, thus creating new challenges for the professionals involved in the computer forensics. The purpose of this study is precisely to analyze the forms that malicious users with personal computers can use to try to obstruct the expert analysis in case of suspect of crim, either by hiding or destroying data, so that the information obtained during the analyzes of this work may help in cases where the presence of any of these techniques. The approach used to carry out the study was the use of simulations of some of these techniques in a controlled environment close to the real scenario and the use of tools focused on expertise and digital research in these scenarios to evaluate the efficiency and main characteristics of these techniques, generating in this way technical information that may provide an advantage to the expert or digital investigator in cases with simliar occurrences to those present in this study.
