Microsoft reported that systems are gradually returning to normal operation following the outage. [^2]

Attackers held access inside Kyivstar, Ukraine's largest mobile operator, for at least seven months before the takedown in December 2023. [^3]

In 2024, Ukraine recorded 4,315 registered cyber incidents with 59 classified as critical, compared to 2,543 incidents in the previous year with 364 considered serious. [^4]

In December 2015, Russian hackers cut electricity for approximately 225,000 customers across three Ukrainian regions after infiltrating networks for months without detection. [^5]

The takedown of the Kyivstar intrusion in December 2023 cut service to roughly 24 million people for one day. [^6]

Some users continue to experience access issues even as systems return to normal. [^7]
