To identify an anomaly in a file, a portion of a file is identified to be used in a vector variance analysis. The portion can comprise sentences or paragraphs for text files, entries, rows, or columns for spreadsheet files, or some other divisible portion of a file. A vector having multiple dimensions is generated for the portion based on the content in the portion. Each dimension of the multiple dimensions 10 corresponds to a feature of the portion. A variance is determined between the vector and one other vector associated with one other portion of the file. An action to take with respect to the file is determined based on the variance, such as ransomware mitigation, and the action is performed with respect to the file."
