碩士 === 正修科技大學 === 資訊工程研究所 === 106 === The ransomware is a kind of malware, its main behavior is to prevent you from accessing computer system or data until you pay a requested ransom. With the booming internet, malicious attacks are increasing rapidly, in which ransomware is raging for making huge profits. After its invasion of your computer, important document files are encrypted so that you can't access again until you get the decryption key by paying the ransom. The ransomware has been the most serious cyber threat in last year, so the year 2016 was called "the year of ransomware". This paper begins with description of study motivation then a brief introduction about ransomware development, followed by discussion of its infection vectors and attack techniques. Finally, a feasible defense strategy is proposed to mitigate the ransomware impact and reduce the suffered losses.
