Hunter Listed by spacebears Ransomware Group

On May 19, 2026, business contact intelligence platform Hunter appeared on the leak site of the spacebears ransomware group after internal files were exfiltrated during a ransomware attack. The company, used by sales teams, recruiters, and marketers worldwide to find and verify professional email addresses, had its data taken when attackers breached its systems. Anyone who maintains a Hunter account, has searched for contacts through the service, or appears in the millions of business profiles it indexes may now have their information circulating in criminal channels.

Confirmed Facts from Reporting

Public reporting indicates the incident stems from a ransomware deployment where attackers first gained access, exfiltrated internal files, and later listed Hunter on their data leak portal. The data exposed consists of internal files rather than a simple database dump. Hunter was founded in 2015 by Antoine Finkelstein and François Grante, initially as Email Hunter, and grew rapidly due to its browser extension and affordable pricing model. No confirmed victim count has been released, and the precise volume or sensitivity of the stolen files remains unclear from available reporting. The listing appeared on the spacebears leak site hosted on the dark web.

Why This Matters for You and Your Family

If you or anyone in your household has ever used Hunter to locate business emails, the credentials or associated personal details tied to your account could now be in attackers’ hands. That information often links to your workplace email, personal accounts, or client lists. For families, the risk extends beyond one person: a breach like this can expose contact details that appear in shared professional networks, making it easier for criminals to target spouses, partners, or even older children whose school or activity emails surface in business data sets. Once criminals hold fresh leaked data, they can launch credential-stuffing attacks or build convincing phishing messages that reference real professional relationships.

The Doxxing and Identity-Chain Implications

Leaked internal files from a service like Hunter rarely stay isolated. Attackers frequently cross-reference newly obtained emails, usernames, and company associations with information from previous breaches. This creates an identity chain that can reveal your home address, phone numbers, family member names, and even children’s online handles. Credential leaks like this one cascade into account takeovers and doxxing chains, especially when gaming accounts or family-shared logins reuse similar passwords. A single exposed work-related email can lead to mapping your entire digital footprint across social media, shopping sites, and children’s gaming platforms.

Spacebears Group Track Record

Public reporting attributes the attack to the spacebears ransomware group. The group emerged in recent years and has targeted organizations across multiple sectors by deploying ransomware, exfiltrating data, and then pressuring victims through public leak sites when ransoms go unpaid. Their typical playbook involves initial access through common vulnerabilities or phishing, followed by data theft and extortion demands that escalate to full publication of stolen files. Notable prior victims have included companies whose internal documents were later posted on dark-web leak portals similar to the one now listing Hunter.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real-world identity across 15.4B+ breach records and 100+ platforms.
• Rotate any password you used with Hunter anywhere else it is reused, then enable 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring so the next breach exposing you or your family is caught in hours, not months.
• Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts that often chain back to the same addresses and emails.
• Let remediation specialists handle takedown requests across data brokers and exposed profiles for you.
