Pennington County is responding to a cybersecurity incident affecting portions of its network, prompting the closure of most public-facing county offices today.
County officials said critical public safety services will remain operational, including 911 Dispatch, the Pennington County Jail, the Juvenile Services Center, the Care Campus, and other emergency response functions. Court operations, the 24/7 Program, and early voting at the Pennington County Auditor’s Office from 7 a.m. to 4 p.m. will also continue as scheduled.
While county staff work to assess the incident and restore systems safely, vehicle registration services remain available online through my605drive.sd.gov and at self-service kiosks.
Officials said the full scope of the cybersecurity incident has not yet been determined. Pennington County is working with the South Dakota National Guard Cyber Incident Response Team, the South Dakota Fusion Center, the Cybersecurity and Infrastructure Security Agency (CISA), and other partners as the investigation continues.
Because the investigation is ongoing, county officials said limited verified information is currently available and expect to provide their next public update by 11 a.m. this morning.
