1.6M RingCentral accounts' data dumped after ShinyHunters extortion attack

A reported social‑engineering breach of RingCentral by the ShinyHunters extortion group led to the online publication of approximately 1.6 million customer records (names, emails, addresses, phone numbers). RingCentral said a targeted voice‑phishing attack allowed unauthorized access, it engaged a third‑party forensic firm and implemented remediation, while ShinyHunters publicly posted data after failed extortion negotiations.
