Android ransomware detection using reduced opcode sequence and image similarity

摘要: Nowadays Ransomwares are not limited to personal computers. Increasing the number of people accessing cell phones, availability mobile phone application markets along with lack an effective way for identifying have accelerated their growth and expansion in field phones IOT. In following article, optimal approach is presented that transforms sequence executable instructions into a grayscale image then LDA used two phases. statistical method separating or more classes dimension reduction. first phase, because size large it contains information reduces accuracy rate, its best features exploited using LDA. next fit train data sample tests feeded prediction. The experimental results on well-known Ransomware families unknown group show suggested capable 97 percent accuracy.
