BONI-PASSAU.DE Listed by cloak Ransomware Group

If you are a customer of Boni-Passau.De, here’s what is being claimed, and what it would mean for you.

Boni-Passau.De was listed on Cloak's leak site. Cloak claims to have stolen internal data. This is the group's claim, not a confirmed finding.

BONI-PASSAU.DE Listed by cloak Ransomware Group

On August 24, 2023, the German municipal service provider BONI-PASSAU.DE appeared on the leak site of the cloak Ransomware Group. The listing states that internal files were exfiltrated during a ransomware attack; the exact number of records affected and the specific data types contained in those files remain unknown because the disclosure does not quantify them.

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 582 companies.

Reported Details from the Leak Site

The primary source, the cloak ransomware leak page (archived on ransomware.live), lists BONI-PASSAU.DE as a victim and claims successful data exfiltration. It does not publish sample files, specify the volume of data taken, or list particular categories such as customer records or employee information. The notification simply confirms that files were allegedly stolen and that the victim has not yet met the group’s demands. Public reporting on cloak indicates the group follows a double-extortion model: encryption of systems combined with threats to publish stolen data if ransom is not paid.

Why This Matters for You and Your Family

When a local government-adjacent organization like BONI-PASSAU.DE suffers a breach, ordinary residents of the Passau region are often the ones whose personal information ends up in the hands of criminals. Even though the exact contents are not detailed, internal files from a public-service provider frequently include names, addresses, dates of birth, tax identifiers, or correspondence that can be used for identity theft or targeted scams. If your family has interacted with municipal services in that area in recent years, your information could be among the stolen material. The uncertainty itself creates risk: you cannot protect against a threat you cannot see.

Doxxing and Identity-Chain Risks

Stolen internal files rarely stay isolated. Attackers and subsequent buyers routinely cross-reference names, email addresses, and phone numbers found in one breach against dozens of other leaks. This creates long identity chains that link your work email to your personal accounts, your children’s school records, and even gaming usernames. A single municipal breach can therefore accelerate doxxing campaigns, SIM-swapping attempts, or spear-phishing attacks aimed at your household. Credential leaks like this one cascade into account takeovers, especially when the same passwords are reused across personal and family gaming platforms.

Cloak Ransomware Group Track Record

Public reporting attributes cloak as a ransomware operation that emerged in early 2023. The group has claimed responsibility for attacks on organizations across Europe, typically targeting mid-sized companies and public-sector entities. Their playbook follows a now-familiar pattern: initial access gained through phishing or exploited remote desktop services, followed by rapid exfiltration of documents before deploying encryption. They maintain a leak site where they publish victim names and, in some cases, proof-of-data samples to pressure payment. Like many contemporary ransomware actors, cloak combines technical extortion with public shaming, giving victims a short deadline before data is released or sold.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup of exposed data by Warden specialists.
  • Rotate any password you have ever used for BONI-PASSAU.DE or related municipal portals anywhere it is reused, and switch to 2FA through an authenticator app rather than SMS.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information surfaces you are alerted within hours instead of months.
  • Cover the household with DoxxScan family protection that extends to dependents and your children’s gaming accounts, which often become the weakest link in doxxing chains when credentials leak.
  • Let remediation specialists handle takedown requests across data brokers and extortion sites on your behalf while you focus on securing day-to-day accounts.

The BONI-PASSAU.DE incident is a reminder that even regional public-service providers hold information that can endanger ordinary families for years to come. Staying ahead requires more than reactive checks; it demands continuous visibility and expert intervention. DoxxScan by GalaxyWarden delivers exactly that through continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts. Start your DoxxScan trial today and close the gaps before the next leak appears.

Unverified claim — what this report is
This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.
