Technology has made significant advances in a short time, which in turn makes cyberattacks such as ransomware more complex and lethal. Many stakeholders in the computer security sector are investigating ways to counter cyberattacks and especially ransomware. The most frequent results regarding ransomware attacks usually have a focus on avoiding the introduction of malicious vectors to the systems, using machine learning, artificial intelligence, an ailment that this approach entails is when the defense is breached, the system is completely exposed. and therefore, access and control of all files.
The approach or premise that the article investigated in this document focuses on is to protect important documents against a ransomware attack, making use of the principle of Git (version control system), it is about having versions or copies protected at the level editing and access permissions for documents that the user considers important. Part of the research contemplates the implementation of this concept in the form of a component or extension for Microsoft Word so that automatically when a document is finished working, a new copy of the latest changes is generated. The impact on performance during the execution of the plugin on a computer is also evaluated. As an additional value to the research, the implementation of SHA 256 encryption of documents is contemplated and analyzed as an additional layer of security.
