Hunter
About the organisation
Hunter was created by Antoine Finkelstein and François Grante in 2015. Freshly graduated, they saw the untapped potential of cold emails and wanted to address the challenges of prospecting and finding contact information. To achieve great success rate while complying with privacy regulations, they decided to use emails found on the public web. Email Hunter was born. Soon rebranded as Hunter, the tool quickly became a game-changer in business intelligence. Within weeks, it attracted thousands of users thanks to its user-friendly interface, handy browser extension, affordable pricing, and data accuracy. Unlike its peers, Hunter aimed not at large enterprises but at making cold emailing accessible to all. Over time, Hunter grew into a comprehensive email outreach platform, offering everything from finding contact information to sending cold emails. Antoine and François, with a focused team, continued to empower professionals with simple, powerful tools.-Personal information of employees and clients-Databse-Financial documents-Other files https://hunter.io/
What the listing means
Hunter appeared on the spacebears leak site on 26 May 2026. Groups publish a victim once negotiations stall or as pressure during them, so a listing usually means data was already exfiltrated — the attack itself is dated 19 May 2026, 7 days before the listing. This group has published 7 claims in the last 30 days and remains active.
Recommended actions
- Treat any unsolicited message referencing Hunter as suspicious — leaked data gets weaponised for phishing within days.
- If you hold an account on hunter.io, change that password now, update it anywhere you reused it, and enable two-factor authentication.
- Watch for follow-on extortion: stolen data is often re-leaked or resold after the initial listing.
- A leak-site listing is a claim made by the attacker, not a confirmed breach — check the organisation's own disclosures before acting on it.
