Abstract
The present disclosure is directed at systems and methods for detecting ransomware infection in filesystems. These systems and methods may enable a computer user to detect a ransomware infection within a filesystem utilizing a snapshot image-based backup. According to some embodiments, the disclosed systems and methods analyze metadata describing the contents of an examined filesystem embodied in a Master File Table (MFT). Also according to some embodiments, the disclosed systems and methods compute an entropy associated with an extracted sample of files to distinguish between infected and uninfected file systems. Relative to other techniques, the disclosed systems/methods can decrease the time and/or computational resources required to detect ransomware, while also decreasing false positives and false negatives.
