Ransomware attack (RWA) detection is performed during an incremental or differential backup of a system of folders or directories of a computer or network of computers via an electronic network. The RWA detection includes processing incremental or differential backup metadata acquired during the incremental or differential backup to determine whether a RWA alert is issued. RWA remediation is performed at least in part on the RWA alert being issued. The RWA alert may be issued based on processing of the incremental or differential backup metadata to identify candidate new files and candidate deleted files in which the candidate new files are candidates for being encrypted copies of the candidate deleted files. RWA alert criterion may be based on counts of new versus deleted files in a folder or directory, and comparison of file sizes of the new versus deleted files.

Methods and systems for detecting ransomware attack in incremental backdrop

This disclosure and the exemplary embodiments described herein, provide methods and systems for detecting a ransomware infection in one or more files. According to an exemplary embodiment, a low frequency encryption analysis and a high frequency encryption analysis of a plurality of received files is performed to determine if the one or more of the files are encrypted. If a file is encrypted, a watcher is utilized to monitor file events associated with the files for determining if one or more of the files are infected with ransomware.

Methods and systems for detecting a ransomware attack using entropy analysis and file update patterns

Ransomware detection and/or isolation and/or remediation of a ransomware-encryption device is performed in a Remote Monitoring and Management (RMM) system environment. The RMM system is operatively associated with monitoring and managing a plurality of devices and, according to an exemplary embodiment, the RMM system includes a RMM agent module locally installed on each device, a cloud-based RMM platform operatively communicating with each device RMM agent module, and a Ransomware Detection (RD)/Isolation module locally installed on each device. The RD/Isolation module locally detects a potential ransomware-encryption in one or more files received by the device and the RMM system isolates a ransomware affected device using a locally executed script provided by the cloud-based RMM platform.
