Abstract
A computer-implemented method for measuring entropy during file backups may include (i) detecting an initiation of a backup process for a backup image including multiple files, wherein each of the files is associated with a set of blocks, (ii) sampling, during the backup process, a random selection of a fraction of the blocks associated with each of the files, (iii) determining an entropy value for the files based on the sampling, and (iv) performing a security action that identifies potential ransomware activity in the backup process based on the entropy value corresponding to a presence of encrypted data in the files. Various other methods, systems, and computer-readable media are also disclosed.
