95% of government websites affected by cyber attack restored
Within the relevant criminal proceedings, the SSU is investigating the cyber attack on state institutions and private enterprises on the night of January 14, 2022.
The investigators established that during the attack there was an unauthorized change in the pages of sites, and the IT-infrastructure of state authorities using products of the same developer was affected. The developer was also affected in the incident.
The attack used vulnerabilities of the website content management systems (OctoberCMS) and Log4j, as well as compromised accounts of the developer’s employees.

Currently, the investigators are collecting digital evidence, analyzing malicious software and log files of the affected systems.
95% of sites affected by the cyber attack against state information resources have resumed operation.
