No specific details were provided regarding the timeline of intrusion detection or the exact systems initially breached. The incident caused operational interruptions to public services, though the duration of these disruptions was not quantified in available reports. Municipal officials did not disclose whether forensic investigations identified vulnerabilities exploited by the attackers or whether data recovery efforts were undertaken.
