Abstract: Ransomware has been among the most important threats to the economy and security of companies for many years. This type of malware aims to encrypt the data of a company to ask the victim for a ransom in exchange for decrypting it, usually through Bitcoins, since they are more difficult to track. A ransomware attack can completely paralyze the activity of the infected company, so the economic impact is great and causes serious damage to the reputation. In recent years, much more targeted and increasingly intelligent attacks are being detected that steal information before encrypting it to demand larger ransoms, threatening to make the data public, which can lead to serious administrative fines according to current legislation. The complexity to resolve ransomware attacks afterwards is so high that in many cases the encrypted data cannot be recovered, which is why the best way to defend oneself is prevention through a combination of tools, good practices, and cybersecurity training. The objective of this final master's dissertation is to study ransomware, detailing the attack vectors most used for its distribution and providing guidelines and tools so that both SMEs and individuals can reduce the risk of infection.
