Main server outage hits Dekalb County Sheriff’s Department, disrupting email and inmate booking systems.
-
The Tennessee Bureau of Investigation and the FBI are now helping to look into what happened.

Officers have recovered booking data, but they haven’t confirmed if the hackers just stole data or if they demanded ransom.
Early Friday morning, the DeKalb County Jail’s computer system stopped working right when correctional officers were in the middle of booking an inmate.
Sheriff Patrick Ray said the booking program froze up completely. Then they later discovered it was a ransomware attack, not a normal glitch.
DeKalb County Jail System Went Down During Active Booking
The jail’s main server went offline, taking both the department email and booking software down with it. Sheriff Patrick Ray told reporters at local radio station WJLE that the affected system controlled “other things” too. But he wasn’t specific about what other things the incident affected.
Staff jumped into crisis mode with their booking software vendor and, somehow, managed to get the booking data back online by Friday night. But email services? They still haven’t restored those. And the Sheriff’s office didn’t say when it’s going to be back on or what other systems may have taken a hit too.
Based on what Sheriff Ray said, the FBI and the Tennessee Bureau of Investigation jumped into the case immediately. They are working to see how to go about handling the situation.
Ongoing Investigations
A third-party firm will check the system to see what happened and try to get back anything that the department lost. Nobody in the sheriff’s office has said whether the hackers actually asked for ransom or not.
Ray did mention, though, that another sheriff’s department in Tennessee took a similar hit not long ago. But, he mentioned no names. And he was of the opinion that maybe it’s foreign hackers, nothing’s certain as of now.
Currently, there are no indications of any hacker groups claiming responsibility for the attack. The sheriff’s office hasn’t gotten back to the media with all the details about what went down.
Tennessee Agencies Face Many Cyber Threats
It’s not the first time this has happened in Tennessee, either. Local governments seem to be a new favorite playground for cyber crooks. Last October in La Vergne, officials spotted some kind of network meltdown.
They invited the FBI and TBI to sort things out as well. The incident didn’t disrupt Public safety and utilities operations, but still, the chaos showed how vulnerable local governments can be.
Additionally, the Hamilton County Sheriff’s Office, back in April 2025, also experienced its share of ransomware attacks. The incident totally forced all their online services to go offline while they invited external experts to work on restoring it.
The Implications and Next Step
Teams from both state and federal levels have swung into action and are hoping to sort things out ASAP.
There’s still no word concerning what cybercriminals might have stolen: Inmate records? Staff information? Or case files? Also, everybody wants to know: Did they steal data? Did they demand ransom?
With just about 20,000 living there, DeKalb County is a small community in Middle Tennessee, basically in Nashville’s backyard. A small sheriff’s office like DeKalb’s won’t find it easy to navigate a cybersecurity incident.
When you can’t book inmates, and email’s not working, everything basically grinds to a halt. And communicating with other agencies and the public becomes an issue.
Right now, all anyone can do is wait for updates and hope recovery moves faster. DeKalb County just got a harsh reminder: Ransomware doesn’t care how big or small the target is; everybody gets a fair shot.
That includes medical practices like the one in Columbia, where patients’ Social Security numbers ended up in criminals’ hands, proving that whether you’re a county jail or a healthcare provider, the threat is real and the consequences are devastating.
