Little attention is paid to such information operations and approaches to their detection. The paper deals with the detection of such information effects using Exploratory data analysis, fractal and wavelet analysis, as well as factor structure analysis using neural networks for being defensive, understanding of methods and techniques used to attack in Informational Space is necessary.
