Cyber Security Insight #3 – 2024

We have updated the format of our reports. They will come out several times every month and be more focused on one event. The new name is NTT Cyber Security Insights.

While Russia’s military invasion of Ukraine continues, cyberattacks are
intensifying. On December 12, 2023, Kyivstar, the country’s largest
telecommunications company, was hit by a massive cyberattack that
knocked out mobile and internet services used by millions of people and disrupted air raid siren systems in parts of Kyiv. The attack appears to
have involved Russian state-sponsored attackers and was one of the most significant cyberattacks on Ukraine’s critical infrastructure.
