IT threat evolution in Q1 2026. Mobile statistics IT threat evolution in Q1 2026. Non-mobile statistics In the third quarter of 2025, we updated the methodology for calculating statistical indicators based on the Kaspersky Security Network. These changes affected all sections of the report except for the statistics on installation packages, which remained unchanged. To illustrate the differences between the reporting periods, we have also recalculated data for the previous quarters. Consequently, these figures may significantly differ from the previously published ones.

However, subsequent reports will employ this new methodology, enabling precise comparisons with the data presented in this post. The Kaspersky Security Network (KSN) is a global network for analyzing anonymized threat information, voluntarily shared by users of Kaspersky solutions.
