ZenBusiness Data Breach (2026)

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

In March 2026, the hacker and extortion group "ShinyHunters" claimed to have obtained a substantial corpus of data from ZenBusiness, a business formation and compliance platform. The group claimed the data had been exfiltrated from platforms including Snowflake, Mixpanel and Salesforce, and threatened to publish it if a ransom was not paid. The following month, after claiming payment had not been made, ShinyHunters publicly released the data. The collection amounted to many terabytes across thousands of files that appeared to originate from multiple systems and business functions, including le

On March 27, 2026, the hacker and extortion group ShinyHunters publicly released more than 5.1 million records stolen from ZenBusiness, a platform used by small-business owners to form companies and maintain compliance. The exposed information includes names, email addresses, and phone numbers. The group had first claimed the breach in March, stating the data came from Snowflake, Mixpanel, and Salesforce systems, and warned they would publish it if ransom demands went unpaid. In April they followed through and dumped the files online.

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

Public reporting indicates the incident involved many terabytes of data spread across thousands of files. The collection appeared to draw from multiple internal systems and business functions at ZenBusiness. Have I Been Pwned lists the breach and confirms the three categories of personal information that were exposed. The timeline is clear: claim of breach and ransom demand in March 2026, followed by public release the next month after the group said payment was not received. No evidence has surfaced that payment was made.

Why This Matters for You and Your Family

If you have ever used ZenBusiness to register an LLC, file paperwork, or manage compliance, your contact details are now available to anyone who downloads the archive. Names, emails, and phone numbers are the basic building blocks attackers need to launch phishing campaigns, SIM-swapping attempts, or identity-theft schemes. For many families this data sits alongside information already leaked in other breaches, making it easier for criminals to build a convincing profile of you. Children who share a family email address or phone number can also be pulled into these chains, especially when gaming accounts or school-related logins reuse the same credentials.

The Doxxing and Identity-Chain Implications

Once names, emails, and phone numbers are public, attackers can link them to usernames on social media, gaming platforms, and shopping sites. This creates an identity chain that quickly reveals home addresses, family relationships, and financial details. Credential leaks like this one routinely cascade into account takeovers. A compromised ZenBusiness email can be used to reset passwords on banking, tax, or shopping accounts. Gaming accounts belonging to you or your children are particularly vulnerable because they often rely on the same email or phone number and can be hijacked to harass or extort the household.

ShinyHunters Track Record

Public reporting attributes the ZenBusiness incident to ShinyHunters, a group that emerged several years ago and has targeted numerous organizations in the technology and consumer sectors. Notable prior victims include large online services and data platforms where the group followed a consistent playbook: gain initial access, exfiltrate large volumes of customer records, issue a ransom demand with a short deadline, and then publish the data on leak sites when payment is not made. Their extortion style relies on the threat of immediate public release rather than prolonged negotiation.

What to do

Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup handled by the service.
Rotate the password you used at ZenBusiness anywhere it is reused and enable 2FA through an authenticator app instead of text messages.
Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure is caught in hours rather than months.
Cover the household with DoxxScan family coverage that extends to dependents and children's gaming accounts that chain back to the same contact details.
Let the remediation specialists perform hands-on takedown requests across data brokers and exposed records on your behalf.

The most important step is to treat every new breach as a link in a growing chain rather than an isolated event. Starting your DoxxScan trial gives you continuous monitoring across billions of records, AI-powered identity-chain mapping that connects scattered online handles to your real identity, and direct assistance from specialists who manage removal work for the entire household, including children's gaming accounts.

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.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
