Ransomware gang Interlock today took credit for an October 2025 cyber attack at the Shelbyville Police Department in Shelby County, Kentucky.
Police Chief Bruce Gentry on October 15 announced a cyber attack disrupted the department’s computer network, according to WAVE.
In a post on its data leak site, Interlock now says it stole 208 GB of data from the Shelbyville Police Department, including police camera recordings. To prove its claim, Interlock posted sample images of what it says are files stolen from the department.
Shelbyville Police have not verified Interlock’s claim. We do not know what data was compromised, if the department did or will pay a ransom, or how attackers breached the department’s network. Comparitech contacted the department for comment and will update this article if it replies.
Who is Interlock?
Interlock is a ransomware gang that first started claiming attacks on its leak site in October 2024. Its malware both steals data and locks down computer systems. Interlock then demands a ransom to restore infected systems and secure stolen data.
The group started claiming responsibility for attacks on its data leak site in October 2024. Since then, it’s claimed 72 ransomware attacks. 35 of those were confirmed by the targeted organizations.
Interlock is the confirmed attacker behind five other data breaches at government entities:
- Wayne County, MI reported a data breach in October 2024
- Noblesville, IN notified 1,841 people of an October 2024 breach
- West Lothian Council, UK reported a May 2025 data breach
- St. Paul, MN refused to pay Interlock following a July 2025 breach
- Box Elder County, UT reported a data breach in August 2025
Interlock has claimed responsibility for 25 confirmed attacks and 33 unconfirmed attacks this year.
Ransomware attacks on US government
Comparitech researchers have logged 68 confirmed ransomware attacks on US government entities in 2025.
In addition to those listed above, Sugarland, TX officials reported 11 days of downtime following an October 2025 data breach claimed by Qilin.
Last month, the Chester County, PA Library System notified 1,281 people of a September 2025 breach that led to several weeks of system disruptions. Lynx took credit for that attack.
Ransomware attacks on government entities can both steal data and lock down computer systems. They can disrupt any number of government systems from bill payments to court records and even emergency dispatch. Organizations must pay a ransom for the stolen data and to restore systems, or else they face extended downtime, permanent data loss, and putting data subjects at increased risk of fraud.
