Cyberattacks against computer systems with the intention of gathering data from various institutions' data systems are allegedly the responsibility of each individual. Attackers gained unauthorized access to sensitive data and classified information kept in various government ministries as a result of the cyberattacks. This included vital information that jeopardized the security of the impacted institutions, such as medical records and business secrets.
