RingCentral customer data from about 1.6 million accounts was exposed after attackers breached the company in July 2026. RingCentral said the intrusion followed a sophisticated social-engineering campaign, and Have I Been Pwned said leaked data tied to the ShinyHunters extortion claim includes names, email addresses, phone numbers, and physical addresses. The gang reportedly stole 623GB and later leaked about 280GB after RingCentral did not pay.
Why it matters: This affects a major business communications provider used by hundreds of thousands of organizations, so exposed contact data could fuel phishing, vishing, and impersonation attacks. Affected customers should watch for targeted scams, review RingCentral-related access logs, and reset or harden accounts if notified.
