Moskollectora is responsible for the operation of underground water pipes, communication cables, power cables and heating networks in the Russian capital. Ukrainian hackers disabled 87,000 sensors of various warning systems across Moscow and the Moscow region. In addition, 70 servers and at least 90 terabytes of company data (emails, backups, contracts) were destroyed. This was reported by UNN's own sources.
According to sources, it was an operation of the BLACKJACK hacker group, which is close to the SBU cyber department.
"At the moment, the operation of the critical infrastructure facility in Moscow is completely blocked, and the company cannot respond to accidents and emergencies. It will take 15 to 30 days to restore its operation. We wish various man-made disasters to Moscow these days," the source told UNN.

Earlier, UNN sources reported that Blackjack hackers, together with the SBU cyber department, destroyed the Russian data center OwenCloud.ru, which was used by the Russian military-industrial complex, oil and gas, and telecom. More than 300TB of data was eliminated.
