CYBER INCIDENTS FROM THE PERSPECTIVE OF THE NÚKIB In 2020, the NÚKIB received 468 notifications of cyber security incidents, 99 of which it directly handled (Chart 13). The remaining incidents either did not re­ quire any intervention from the NÚKIB, or another relevant institution handled them. Nearly one-third of the handled incidents were reported by nonregulated entities, which represents nearly a tenfold increase compared to 2019. This increase is highly likely (75% – 85% probability) caused by the higher number of cyberattacks as well as improved awareness of the existence and activities of the NÚKIB.
