On February 9, 2026, the town of Hanover, Massachusetts, appeared on the LockBit 5 ransomware group's leak site. The listing indicates that internal files from the Hanover Police Department were exfiltrated during a ransomware attack. Public reporting leaves the exact number of affected residents unclear, but anyone whose personal information passed through town or police systems could be exposed.
Already exposed?
You can’t unleak data. You can take away what it’s worth.
A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

What Public Reporting Shows
Available reporting describes the incident as a ransomware deployment that led to data exfiltration. The files were posted to the LockBit 5 leak site, a dark-web location used to pressure victims. The Hanover Police Department is explicitly named in the posting. No confirmed total of records or specific data fields has been released by the town, though internal documents of this type frequently contain names, addresses, dates of birth, driver's license numbers, incident reports, and employee records. The town has not yet issued a public statement detailing the volume or sensitivity of the leaked material.
Why This Matters for You and Your Family
When a local police department loses control of its files, the impact reaches far beyond town hall. Residents who filed reports, applied for permits, interacted with officers, or appeared in any departmental record now face heightened risk of identity theft and fraud. Your family could be targeted even if you live outside Hanover, because police databases often include information from surrounding communities. Criminals can use stolen details to open accounts, file false tax returns, or impersonate you in official correspondence. Children’s records, if present, are especially concerning because early identity compromise can follow them for decades.
The Doxxing and Identity-Chain Implications
Exposed police files rarely exist in isolation. A single leaked address, phone number, or email can be cross-referenced with gaming accounts, social-media handles, and data-broker profiles to build a complete picture of your household. This process, known as identity-chain mapping, turns one breach into multiple attack surfaces. Public reporting indicates that ransomware groups increasingly sell or publish these linked datasets, enabling doxxing campaigns that reveal home addresses, family member names, and even children’s online usernames. Once the chain begins, opportunistic criminals can escalate from identity theft to harassment or physical threats.
