Town of St. Marys

The Town of St. Marys is a municipal government located in Canada.
It provides essential public services that include fire protection, policing, public transit, and water supply and management.
These services continued to operate even when the town’s internal servers were compromised by a ransomware attack in July 2022.

On 2022-07-20 the LockBit ransomware group attacked the Town of St. Marys, encrypting internal servers and threatening to release stolen data unless a ransom was paid.
Despite the encryption, the town confirmed that fire, police, transit, and water services remained operational throughout the incident.
Officials responded by engaging cybersecurity experts, legal counsel, and law enforcement to investigate the breach and mitigate its impact.
The attack was publicly disclosed on the town’s website and noted on LockBit’s dark‑web leak site.
During the incident, the town’s public-facing websites and service portals displayed notifications informing residents of the ongoing investigation.
The town collaborated with cybersecurity experts and legal counsel to address the breach, as stated in official communications.
This incident exemplifies LockBit's prominence as a leading ransomware operator responsible for a significant portion of global extortion attacks during that period.
