Abstract

Data detection techniques involve: determining count features respectively corresponding to a plurality of time points based on data blocks of a storage object; determining, for a first time point among the plurality of time points and according to the count features respectively corresponding to the plurality of time points, a plurality of corresponding correlation coefficients between a count feature for the first time point and count features for the other time points among the plurality of time points; and determining, if a score calculated according to the plurality of correlation coefficients is less than a predetermined threshold, that the storage object corresponding to the first time point is under attack. Accordingly, a storage system can be protected, and the point in time when it is attacked by malware can be quickly located, which improves checking efficiency, saves checking costs, and helps users to quickly recover stored data.
